Thin-Walled Tapered Roller Bearings

Automatic Transmission

 Overview

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.

 Product List

Friction Plates/Separator Plates

Sprag-Type One-Way Clutches

Lightweight, compact, and reliable shifting can be achieved.

 

Flex Bands/Maji Bands

Unique friction materials produce an excellent and smooth shift quality.

 

Friction Clutch Assemblies

The compact design for high torque capacity is established.

 

Hydraulic Lock-up Clutches

An optimal design to maximize functionality of the clutch.

 

Roller-Type One-Way Clutches

A traction control system is achieved with high anti-shudder performance.

 

The action of roller and spring reduce drag torque remarkably.

 

Thrust Needle Roller Bearings for Drive Train

Thrust Needle Roller Bearings for Torque Converter

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

 

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


 

 

Drawn-Cup Needle Roller Bearings for Power Train

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


 

 

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


 

 

Cage & Roller Assemblies and Shaft for Planetary Gears

Drawn-Cup Needle Roller Bearings for Shift Linkage

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

 Related Industries

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

 

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


 

 

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.


 

 

Maximum capacity in a limited space (thin section) has been achieved by high-level design technology, which promotes greater compactness of FF-type
                                           automatic transmissions.


 

 

Linear Bearings for Solenoid Valve

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


 

 

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