Tapered Roller Bearing

Angular contact tapered roller bearings are designed to accommodate combined simultaneously acting radial and axial loads. The bearing ability to accommodate the axial load is largely determined by the taper angle of the outer ring raceway, called contact angle. When increasing the contact angle, the axial load capacity of the bearing increases with the corresponding decrease of the radial load capacity and permitted rotation speed. Even slight shaft misalignment relative to the housing is unacceptable when using angular contact tapered roller bearings.

Angular contact tapered roller bearings are produced single row accommodating only axial load in one direction, as well as double row and four-row accommodating axial load in both directions. It is possible to supply single row bearings matched in pairs and completed with intermediate rings to secure the necessary clearance. In the general engineering fields, the most common are single row bearings, double row and four-row bearings are usually used in the heavy machinery. Angular contact tapered roller bearings have a split design, which makes their mounting easier.

Angular contact tapered roller bearings are produced with pressed steel cages. Large-size bearings are equipped with massive cages made of steel or brass and for special application cages made of glass fiber reinforced polyamide can be produced.

Deep Groove Ball Bearing

Due to various application possibilities and relatively low prices, deep groove ball bearings are the most common out of all the variety of rolling bearings. They have a simple design and the ability to operate at high speed and moderate load. When operating, they do not practically need maintenance. These bearings are able to accommodate both the radial loads and the axial loads in both directions.

Compared with other types of rolling bearings, deep groove ball bearings operate with minimal friction losses. The alignment of seats for these bearings shall be kept within such limits that the misalignment of the outer rings relative to the inner rings was slight, even with the increased bearing clearance. The bearings shall be mounted on hard double-seat shafts which deflection under the influence of the external forces does not cause excessive misalignment of the shaft axis relative to the mounting bore axis.

Deep groove ball bearings with protective metal shields or contact and contactless seals are widely distributed. They are used in the cases when due to the limited size or maintenance inconveniences, mounting of special sealing devices to protect the bearing from dirt or to keep the lubrication in is undesirable.

Deep groove ball bearings are usually fitted with the pressed steel cages. The bearings with more durable and strong cages made of glass fiber reinforced polyamide, which provide higher speed, low noise, less weight are produced recently. Bearings with the particular requirements, operating in special conditions, as well as large-size bearings, are produced with brass, aluminum alloys, and other materials cages.

Cylindrical Roller Bearing

Radial cylindrical roller bearings are intended to accommodate the radial loads. They have much greater radial load capacity compared to the deep groove ball bearings of equal dimensions, but they are inferior to them as per high-speed characteristics. Cylindrical roller bearings are very sensitive to the misalignment of inner rings relative to outer rings when tension concentration at the edges of rollers appears. To reduce this tension the modern roller bearings contact geometry between roller and raceway has a special «logarithmic» profile.

Single row radial cylindrical roller bearings are produced in many structural modifications, the most common of which are: without flanges and with one flange on the inner ring, with one flange on the inner ring and flat thrust ring, without flanges and with one flange on the outer ring. If it is necessary to reduce the unit radial dimensions, single row roller bearings can be supplied without inner or outer rings, in this case, the second raceway is formed directly on the shaft or in the housing of the unit. Double row and multi-row radial cylindrical roller bearings are produced for various special applications.

Radial cylindrical roller flanges ring. If it is necessary to provide extremely high radial load capacity, these bearings can be bearings are manufactured with cages made of glass fibre reinforced polyamide, pressed steel cages or machined cages of brass, bronze and aluminium alloys. Machined cages are usually centred on double produced without cages with the maximum number of rollers.

Double Row Angular Contact Ball Bearing

a) General:
These bearings require a good coaxiality between the shaft and the housing.
b) Aptitudes:
This type of bearing allows strong radial and axial loads in the two directions.
A preferential way is sometimes noticed, in case of filling notches. This bearing can be installed alone or together with another bearing (where alignment is necessary).
c) Uses
This type of bearing is used in pumps, reducers (wheel and screw), equipment…

Integral Shaft Bearing

Due to their design, integral shaft bearings are very compact, allowing for either two rows of balls or a row of balls and a row of rollers. Our bearings are pre-packed with lubricant to ensure a long lifespan and are sealed to resist contamination.
If you need some more flexibility when it comes to integral shaft bearings, outer race and shaft diameter variations are available, as are shaft extension modifications. It’s this flexibility that allows integral shaft bearings to be used in a number of applications, including those in the automotive, agricultural, and landscaping industries.

Needle Roller Bearing

Small cylindrical rollers with the length are several times more than their diameter is called needle rollers.

Radial needle roller bearings are designed to accommodate only radial loads. With the equal load capacity, they have much smaller radial dimensions compared to the dimensions of other types of bearings having with them the identical hole diameters. This property makes them very popular to use in the machines with limited radial space. A negative characteristic of the bearings is their extremely small capacity to accommodate the angular shaft misalignments relative to the housing.

The radial needle roller bearings have enormous kinds of designs. The most common are bearings with the pressed outer rings, with the rings made of bearing steel, as well as the cages with the rollers without rings. Usually, the bearings have one or two rows of rolling elements. The bearings can be open or have protective contact seals.

Radial needle roller bearings are produced with pressed steel or glass fiber reinforced polyamide cages. To provide a very high radial load capacity the bearings can be manufactured without the cage with the maximum number of rollers.

Pillow Block Bearing

A pillow block usually refers to a housing with an included anti-friction bearing. A pillow block refers to any mounted bearing wherein the mounted shaft is in a parallel plane to the mounting surface, and perpendicular to the centerline of the mounting holes, as contrasted with various types of flange blocks or flange units. A pillow block may contain a bearing with one of several types of rolling elements, including ball, cylindrical roller, spherical roller, tapered roller, or metallic or synthetic bushing. The type of rolling element defines the type of pillow block. These differ from “Plummer blocks” which are bearing housings supplied without any bearings and are usually meant for higher load ratings and a separately installed bearing.

RING

Self Aligning Ball Bearing

As a rule, self-aligning ball bearings have two rows of balls with a sphered raceway in the outer ring. This construction feature allows them to withstand the misalignments of the shaft relative to the housing up to 2…3°. Acceptable misalignment angle appearing as a result of shaft deflection under the influence of external load or due to technical machining and mounting inaccuracies is limited by the condition of keeping contact of all the balls in both rows with the working surface of the outer ring raceway. The bearings are designed for the accommodation of radial loads, but can simultaneously accommodate axial loads in both directions too.

The bearings are usually installed in the following constructions: multi-supporting shafts of transmission type; double-supporting shafts subjected to large deflections; units with technologically unprovided strict coaxiality of seats (while boring holes in the housings with more than one pass, when installing bearings in separate housings, etc.).

Self-aligning ball bearings are produced with the cylindrical and tapered bore as well as with extended inner rings. The design with built-in contact seals is also possible.

In the majority of self-aligning ball bearings, the cages are pressed steel or cast glass fiber reinforced polyamide. Large size bearings can be manufactured with machined brass cages.

Spherical Plain Bearing

Spherical plain bearings are plain bearings, inner and outer rings of which have sphered sliding surfaces. Spherical plain bearings are designed for the transmission of radial, axial and combined loads, including shock loads in the joints of machine parts and mechanisms where it is necessary to provide with spatial complex or vibrating, rocking, rotating and simple movements at low speeds. Radial, angular contact, and thrust spherical bearings are produced depending on the nature of transmitted loads.

All spherical plain bearings can be divided into two groups according to the method of the working surface lubrication. There are bearings requiring the lubrication and self-lubricating bearings the sliding surfaces of which are made of special materials. The latter are used in the units with higher durability requirements, or when there are difficulties in supports maintenance when it is unreasonable to use lubrication requiring bearings.

The bearings with protective contact seals are manufactured to protect sliding surfaces from the environmental effects and to keep the lubricant in.

When choosing a type of spherical plain bearing, it is necessary to take into account many factors comprising a number of contradictions to be resolved or optimally balanced.

Square Bore Ball Bearing

Square bore ball bearings are specialty products that exhibit all of the characteristics of standard Single Row Ball Bearings except for the fact the inner ring has a square interior designed for a square shaft as opposed to a round one. These products also are typically in inch dimensions rather than metric. The agriculture industry is one of the largest users of square bore bearings for farm machinery; however, many other industries utilize them.

Steering Bearing

Thrust Bearing

CAN Taper Roller Thrust bearings include rollers that have conical sections. These bearings are designed primarily to support axial loads at contact angles between 30˚ and 90˚. These bearing are suited for applications where extremely high thrust loads like in crane hooks, coal pulverizer, etc. These bearings can be supplied with a full complement of rollers.

Thrust Ball Bearing
The Thrust Ball bearings are used for high axial loads at low speeds. These cannot operate at high speed when centrifugal or radial force cannot be handled by the bearings. They can be located endwise in one direction only.

Spherical Roller Bearing

As a rule radial spherical roller bearings have two rows of rollers with a common sphered raceway in the outer ring. They have higher radial load capacity compared to other types of bearings with equal dimensions and they are able to compensate significant misalignment and shaft deflections (up to 3°). They can also accommodate the combined radial and axial load. However, it is not recommended to operate them under heavy axial loads, because only one row of rollers will work in this case. Radial spherical roller bearings are used in the supports of pumps, powerful fans, smoke exhausts, saw frames, gears, propeller shafts, rolling mills and in the supports of other machines and mechanisms, which operate under heavy radial loads and inevitable misalignment of seats.

Bearings can be produced with both cylindrical and tapered bores in the inner rings. The latter is mounted on the tapered shaft neck or on an adapter or withdrawal sleeve. Radial spherical roller bearings are usually mounted on the long shafts subjected to significant deflection, or in the supports of detached housings. The bearings with adapter sleeves are mounted on smooth multi-supporting shafts. As a rule, bearing with the tapered bore as well as bearings with withdrawal sleeves are mounted on the terminal supports of shaft or axis. The presence of tapered bore in the bearings considerably facilitates their mounting and dismounting.

Lately radial spherical roller bearings in a sealed version with contact seals on both sides are more often used for heavy-duty operation; and usually seals come out slightly the dimensions of the bearing side surface, which requires some extra space in the bearing unit.

Radial spherical roller bearings have pressed steel, glass fiber reinforced polyamide or machined brass cages.

Wheel Hubs

A forged or cast piece of metal that an automobile wheel mounts to. Wheel bearing assemblies typically fit inside the center of the wheel hub to allow free rotation around an axle shaft or spindle. Bearing assemblies that mount inside a wheel hub are often called wheel hub bearing assemblies. Depending on the vehicle manufacturer, some wheel hub bearing assemblies are constructed with integral bearing assemblies that cannot be replaced separately. Instead, the wheel hub must be replaced as a whole. more details on

Tensioner Bearing

Many cars are equipped with belt-driven camshafts. A timing belt is a toothed belt, running over toothed gears. Of course, it is essential that the teeth on the belt can’t jump over the teeth of the gear, because that would change the timing, resulting in poor engine performance or even damage to pistons and valves. So the belt tension should never be too low and never be too high, as that would cause the belt to break, causing severe engine damage too.

On most cars, a tensioner adjusts the belt. This is a pulley, rotating on a bearing and mounted on a slider, so it can be pushed towards the belt to increase the tension.

Belt tensioners are wearing parts. The surface of the pulley will wear down and get rough, the bearing inside the pulley may run dry or develop an excessive play, resulting in noisy operation, vibration and eventually seizing. That will cause the belt to snap, resulting in severe engine damage.

The tensioner pulley should be replaced when replacing the timing belt. Most people prefer to buy a kit, containing the belt, the tensioner, and other pulleys. Some people prefer to buy the parts separately.

Oil Seal

An O-shaped round seal (usually hardened rubber) used to surround part of a bearing assembly so grease doesn’t leak out and water doesn’t get in. Bearing seals are a wear item, and should always be replaced with bearings. If the bearing assembly for your vehicle is not sold with a seal or does not come with a built-in seal, bearing seals can usually be purchased individually. In some cases, these are also known as bearing retainers
