A bearing is a moving device that assists elements rotation in a machine and ensures low friction, and smooth rolling motion. They can be found in all types of machines. Koyo Jtekt’s wide range of premium quality bearings is specially designed for durability and efficiency. Our bearings are easy to handle, highly interchangeable. They can operate in extreme environments (such as very low or high temperatures) and help you save on power. They have the ability to support radial and thrust load as well as high speed rotation. Discover our wide range of premium quality bearings.
Angular Ball Bearings
Designed for high accuracy and excellent high-speed performance. Angular contact ball bearings are designed to carry combined loads: both axial and radial.
Angular contact ball bearings are suitable for applications which require high accuracy and good high-speed performance. This type of bearing is designed to carry a combined load.
Angular ball bearings are available as single or double row, matched pair and four points contact versions.

Cylindrical Roller Bearings
Cylindrical roller 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 machines. Their particular structure results in low friction and allows high-speed applications. Having a separable inner or outer ring, these bearings can be easily mounted and dismounted.
Cylindrical roller bearings are commonly available in precision grades. Typically, they are lubricated with oil, which also serves as a coolant.
Cylindrical roller bearings are used in a variety of applications such as mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. They are available in various versions: single row, double row, full complement, shielded and open types.

Tapered Roller Bearings
This type of bearing is designed so that the cups, cones and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. They are suitable for applications involving heavy or impact loading.
Taper roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers which are profiled to distribute the load evenly. They have high radial and axial (thrust) load capacities at low to intermediate speeds. Taper roller bearings are available in single-row, two-row and four-row designs.

Deep Groove Ball Bearings
Deep grove ball bearings are the most common type of bearings. They are designed to absorb together noise and friction. They are widely used in a large variety of machines and applications.
This type of bearing supports radial and a certain degree of axial load in both directions simultaneously.
Jtekt manufactures a wide range of deep groove ball bearings in various sizes.

Spherical Roller Bearings
These types of bearings are self-aligning and feature a large load rating capacity. Spherical roller bearings are suitable for low and 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.
Spherical roller bearings are available as double-row, combination radial and thrust bearings.

EXSEV and Ceramic Bearings
EXSEV and ceramic bearings are designed to fit in machines where conventional bearings are not suitable. They are highly heat resistant and have a longer service life. Koyo Jtekt has a specific range of bearings specially designed to suit:
Clean environments
Vacuum environments
High temperature environments
Corrosive environments

Ball Bearing Unit
Ball bearing units consist of pre-lubricated sealed ball bearings and a housing unit which varies in shape. Ball bearing units are capable of aligning themselves efficiently using the spherical fitting surface between the bearing and housing, and preventing overloads due to misalignment.
Our Koyo branded Ball Bearing Units are highly accurate and feature excellent load resistance.
We offer a wide range of ball bearing units types such as pillow block, square, oval and round flanged, pressed steel, take up and many more.
