Thrust Ball Bearing

Thrust ball bearings are divided into single and double direction types.

The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions. Neither is suitable for applications that involve radial load or high-speed rotation.

Bearings whose housing washer back face is spherical (with a spherical back face or an aligning seat washer) are designed with a self-aligning capability and can accommodate the effects of inaccurate mounting.

Spherical Thrust Roller Bearings

Spherical thrust roller bearings are designed to carry high axial loads. They can also support radial load if magnitude is no more than 55% of the axial load being carried. These bearings are not suitable for high-speed rotation. Having a spherical housing washer raceway surface, these bearings are self-aligning and capable of adjusting to axial inclination. They are usually used with oil lubrication

Angular contact ball bearing

Available as Single or Double row, Matched Pair and Four Point Contact. Designed for high accuracy and excellent high-speed performance. Angular contact ball bearings are designed to carry combined loads: both axial and radial.

By Product Group

Deep groove ball bearing

JTEKT manufactures a large range of deep groove ball bearings. They are available in a variety of sizes, and are the most popular of all rolling bearings. This type of bearing supports radial and a certain degree of axial load in both directions simultaneously.

By Product Group

Cylindrical roller bearing

Available as Single, Double or Four Row. Features include thrust collars, parallel or tapered bore and lubrication holes and grooves. This type of bearings feature high radial load capacity as the rollers and raceway are in linear contact. Our cylindrical bearings are equally suitable for heavy radial and impact loading.

By Product Group

Spherical roller bearing

These types of bearings are self-aligning and feature a large load rating capacity. Therefore, spherical roller bearings are suitable for low/medium speed applications which involve heavy or impact loading. They come with cylindrical or tapered bores and can be supplied with adapter assemblies as well as withdrawal sleeves.

By Product Group

Tapered roller bearing

Available as single or double row, in metric and inch sizes, they can be produced as either TDO (one double cup and two single row cones) and TDI (one double cone and two single row cups). This type of bearings is designed so that the cups, cones and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. This type is suitable for applications involving heavy or impact loading.

Exsev and ceramic bearing

The Ceramic and EXSEV Bearings are designed for applications operating in extreme special environments where conventional bearings are not suitable for. These bearings have an optimal operation in extreme environments like clean, vacuum, high temperature, corrosive and contaminating conditions. They are already being used in an extensive range of applications and state of the art technologies.

Needle roller bearing

Needle roller bearings are an economical alternative for applications requiring minimal space to carry a given load at a desired speed. They can be an ideal choice because of their ability to handle a given level of speed and load capacity, yet have the smallest cross section of all roller bearing types.

By Product Group

Ball bearing unit

Ball bearing units consists of pre-lubricated sealed ball bearings and a housing which varies in shape. They are capable of aligning themselves efficiently using the spherical fitting surface between the bearing and housing, effectively preventing overloads due to misalignment.

By Product Group

Other

Adapter sleeves, locknuts, lock washers or lock plates are often being used to facilitate the fitting of the bearing on a shaft. These accessories make it easier to (re)assemble the bearing.
