Automatic Transmision Automatic transmissions ensure smooth gear changes with minimal shift shock while operating under various kinds of driving conditions. A complex and extremely intricate form of technology known as friction control is ideal for efficiently conveying power from the engine and for smooth gear shifting.

Friction related parts and one-way clutches, which have been developed based on our advanced tribology technology, are the most important products in determining the performance of automatic transmissions. They contribute to a smooth and powerful driving experience.

Main Shaft Support

Thin Walled Taper Roller Bearings

Offers maximum capacity in a limited space (thin section). This is achieved by high-level design technology which promotes greater compactness of FF-type automatic transmissions.

Long Life Double Row Angular Contact Ball Bearings

Reduced weight and costs have been achieved by using of PA46 plastic cage with superior oil and heat resistance. Initial internal clearance is used to provide optimum preload.

Long Life Double Row Tapered Roller Bearings

Original materials and heat treatment have been developed for longer life. Initial internal clearance is used to provide optimum preload.

Long life tapered Roller bearings with outer mounting flange

The number of parts is reduced by unitization of the housing and outer ring, which also allows for easier assembly.

Long life double row bearings with outer ring splines

The outer ring has a mounting flange and splines, which attached to the one-way clutch. This affords greater compactness of FF-type automatic transmissions.

Cylindrical Roller Bearings with PA46 Plastic Cage

Reduced weight and costs have been achieved by using PA46 plastic cage with superior oil and heat resistance.

Gear Support

Thrust Needle Roller Bearings for Power Train

Selection of the raceway washer and retainer type can be according to operating conditions, such as load, rotation speed, and lubrication.

Thrust Needle Roller Bearings for Torque Converter

A bearing and a raceway washer with anti-rotation function have been combined for easy assembly and high capacity.

Cage & Roller Assemblies and Shaft for Planetary Gears

For coping with increasingly high-speed rotations and low-friction torque while maintaining durability.

Drawn-Cup Needle Roller Bearings for Power Train

From sliding bearings to rolling bearings, low friction torque has been achieved by the technology of thin cross section drawn-cup bearings.

Drawn-Cup Needle Roller Bearings for Shift Linkage

Smoother shifting is achieved by replacing a sliding bearing with a rolling bearing.

Linear Bearings for Solenoid Valve

A special arrangement of balls achieves a reduction of rotational torque and sliding friction torque.
