C-EPS was introduced by JTEKT in 1988 as the world's first "EPS" system. The electric power-assisted unit is located on the steering column, making it ideal for compact vehicles. The mechanism assists the driver in turning the steering wheel through an electric power unit consisting mainly of a motor, an electronic controller and a torque sensor, which, in constant communication with the vehicle's other safety systems and its mechanical parts such as the steering column and gear box, apply the force necessary to steer the wheels. Compared to the hydraulic system that uses the car's engine as a power source, the electric system uses the batte...

BALL BEARING UNITS CONSIST OF PRELUBRICATED SEALED BALL BEARINGS AND A HOUSING THAT VARIES IN SHAPE. They are able to align themselves efficiently using the spherical mating surface between the bearing and the housing, effectively preventing overloading due to misalignment. Our Koyo brand ball bearing units are highly accurate and feature excellent load resistance. They are completely sealed and have a relubrication feature. Ball bearing units without a relubrication feature are also available.

THESE TYPES OF BEARINGS ARE SELF-ALIGNATING AND HAVE A HIGH LOAD CAPACITY. Therefore, spherical roller bearings are suitable for low/medium speed applications involving heavy or impact loads. They come with cylindrical or tapered bores and can be supplied with adapter sets as well as withdrawal sleeves. These bearings are divided into types R, RH(R) and RHA, which differ in their internal structure. Bearings with a tapered bore can be mounted and removed easily using an adapter set or a withdrawal sleeve. The taper ratio is identical among all bearing series: 240 and 241 series: 1:30 (supplementary code “K30”) Others: 1:12 (supplementary code...

Needle roller bearings are an economical alternative for applications requiring minimal space to support a specific load at the desired speed. They are the ideal choice thanks to their ability to handle specific speeds and loads, and they also have the smallest cross-section of all bearing types. At JTEKT, we offer a wide range of premium Koyo needle roller bearings in both metric and inch sizes. Radial needle roller bearings and cages Drawn-cup needle roller bearings Drawn-cup roller clutches Heavy-duty needle roller bearings Support rollers Thrust bearings, assemblies, and washers Combined needle roller bearings Clearance-free ball and need...

THRUST BALL BEARINGS ARE DIVIDED INTO SINGLE AND DOUBLE DIRECTION TYPES. The former is capable of accommodating thrust load in one direction, while the latter is capable of accommodating it in both directions. Neither of them is suitable for applications involving radial load or high-speed rotation. Bearings whose housing washer rear face is spherical (with a spherical rear face or an alignment seat washer) are designed with self-aligning capability and can accommodate the effects of imprecise mounting. Spherical Roller Thrust BearingsSpherical roller thrust bearings are designed to carry high thrust loads. They can also carry radial load if ...

AVAILABLE IN SINGLE OR DOUBLE ROW, MATCHED PAIR AND FOUR-POINT CONTACT. Designed for high precision and excellent high-speed performance. Angular contact ball bearings are designed to support combined loads: axial and radial. Angular contact bearings are designed so that a contact angle is formed between the raceways and the balls when the bearing is in use. The main design feature of this type of bearing is that one or both ring raceways have a relieved or higher shoulder than the other. For these bearings to function correctly, they must be mounted with an axial load. This load (or preload) creates a line of contact (or contact angle) betwe...

AVAILABLE IN SINGLE, DOUBLE OR FOUR ROWS. Features include thrust collars, parallel or tapered bores, and lubrication holes and grooves. This type of bearing has a high radial load capacity, since the rollers and raceway are in linear contact. Our cylindrical roller bearings are equally well suited to heavy radial and impact loads. Cylindrical roller bearings are characterized by high radial and moderate axial load capacities. They contain cylindrical rollers, which, however, are not true cylinders. Instead, they are crowned or relieved at the ends to reduce stress concentrations. This specific geometry results in low friction and allows for ...

CERAMIC AND EXSEV BEARINGS ARE DESIGNED FOR APPLICATIONS THAT OPERATE IN EXTREME SPECIAL ENVIRONMENTS WHERE CONVENTIONAL BEARINGS ARE NOT SUITABLE. These bearings operate optimally in extreme environments such as clean, vacuum, high temperature, corrosive and contaminant conditions. They are already being used in a wide range of applications and cutting-edge technologies.
