Quality guarantee

From raw material to finish products，every process is carried out according to strict standards and products are traceable relying on process tracking card so that all of them meet the international or national standards. 

Technology & service

We provide our clients with a complete set of product solution which is our competitive capacity.

Taking into account of such factors of bearing as speed, life,accuracy and rigidity,our engineers offer bearing design，life calculation，product updating and application maintenance surport.  

The fatigue life of bearings is greatly improved by using high-purity bearing steel to manufacture the inner and outer rings with special heat treatment and cold treatment processes, as well as special raceways with higher precision. 

Achievement and Cases

1.   Bearing for CT

Features:

Large size,thin-wall and long life

High rotation accuracy up to P5 or higher

Low noise and starting friction moment

Mounting holes with high precision

 Bearing for CT

2.   Slewing Bearing for Marine rudder

This type of bearing with spraying or welding anticorrosive material has high reliability and long durability for anti-corrosion by seawater.The bearing dimensions should be matched with seals strictly.
