Deep groove ball bearings

Deep groove ball bearings accommodate radial and axial loads and due to their low frictional torque, they are suitable for high speeds. These bearings are of simple design, durable in operation and easy to maintain. For these reasons and their economical price, they are the most widely used bearings. They are available in single and double row designs and in open and sealed variants.

Angular contact ball bearings

Angular contact bearings are designed such that there is an angle between the raceways and the balls when the bearing is in operation. This means that they can carry axial load in one direction only, and are usually adjusted against another bearing which accommodate the opposed axial load. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. They are available in single and double row designs and in open and sealed variants.

Self-aligning ball bearings

The self-aligning ball bearing is of the double row type with a spherical raceway in the outer ring. This feature gives the bearing self-aligning properties and makes it insensitive to misalignment and shaft deflections. Additionally, self-aligning ball bearings have the ability to keep their temperature low even at high speeds, due to their low coefficient of friction. These bearings are available in open and sealed variants and with either a cylindrical or tapered bore. Bearings with a tapered bore can be mounted directly on a tapered shaft or on cylindrical shaft with an adapter sleeve.

Cylindrical roller bearings

The cylindrical roller bearings are very rigid, can support high radial loads and due to the cage are suitable for higher speeds than the full complement designs. Rollers and raceways feature a modified line contact to eliminate edge stressing. The bearings can be taken apart and can therefore be fitted and dismantled more easily.

Barrel roller bearings

Barrel roller bearings are single row, self-aligning roller bearings. They comprise solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore. Barrel roller bearings are particularly suitable where high radial shock type loads occur and axial misalignments must be compensated. Their axial load carrying capacity is small.

Spherical roller bearings

The spherical roller bearings are known for their heavy duty features. They contain two rows of barrel-shaped rollers which can align themselves freely in the sphered outer ring raceway. This provides compensation for bearing seat misalignment and shaft deflection. This type of bearing incorporates a maximum number of large diameter and extra long rollers. The high degree of roller raceway conformity ensures even load distribution and a high carrying capacity.

Tapered roller bearings

Tapered roller bearings comprise solid inner and outer rings with tapered raceways and tapered rollers with cage. The bearings are not self-retaining and as a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. Tapered roller bearings can support axial loads from one direction as well as high radial loads. They must normally be axially adjusted against a second bearing fitted in a mirror image arrangement.

Axial spherical roller bearings

Axial spherical roller bearings are single row, self-aligning roller bearings. They comprise solid shaft and housing washers and asymmetrical barrel rollers with cages. The bearings can be dismantled and as a result the parts of the bearings can be fitted separately. Axial spherical roller bearings can support very high axial loads and permit relatively high speeds.

Axial deep groove ball bearings

Axial deep groove ball bearings are available in single direction and double direction designs. Both designs can support high axial forces but must not be subjected to radial loads. Axial deep groove ball bearings are separable, i.e. the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately.

Axial cylindrical roller bearings

Axial cylindrical roller bearings comprise axial cylindrical rollers and cage assemblies and shaft and housing locating washers. The bearings have particularly small axial section height, have high load carrying capacity and high rigidity and can support axial forces in one direction.

Needle roller bearings

Needle roller bearings are bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high radial load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.

Insert Bearings

Insert bearings are simply standard radial bearings that fit into a housing and these bearings may be purchased as standalone products to use as replacements. These bearings are used for mounting on shafts without the need for adapters. The bearing is locked in place through setscrews or a locking collar.

Linear ball bearings

Linear bearings provide low friction motion along axis. The bearings can support high loads while having a relatively low mass and allow the construction of linear guidance systems with unlimited travel. Each series have quite specific characteristics that make them particularly suitable for certain applications. These may include, for example, requirements for compensation of misalignments, low‑friction running, high accelerations and travel speeds or long operating life.

Spherical ball bushings

Spherical Ball Bushings are used to accommodate shafts or rods with variable amounts of misalignment. They are designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical stress. Most spherical ball bushings consist of a plain bearing and ball bushing inside a lined, cylindrical housing that reduces friction or provides lubrication. Lubrication-free spherical ball bushings are also available.

Rod Ends

Rod End Bearings are mechanical articulating joints. Rod End Bearings are used on the ends of cylinders, linkages, rods and shafts to take up misalignment between connected parts. They consist of a spherically-shaped inner ring and a cylindrical bore for mounting on a shaft. Rod End bearings attach to rods and shafts via a male stud with external threads or a female housing with internal threads. They are available in right-handed and left-handed threads.
