Technical  Information 

(High Precision Ball Bearing Made to International Brand Standards)

Material

There are essentially two choices for the material used in ball bearings - chrome steel GCr15 (AISI 52100) or stainless steel 9Cr18Mo (AISI 440C). Since the material plays a major part in the performance of a bearing in any given application, it is very important that the correct material is used. The balls are made of GCR15 (AISI 52100), 9Cr18Mo (AISI440C) or Ceramic.

 Precision and Noise Standards

MTWB offers high precision classed P6 or above bearing; customer can select their right vibration/noise level hence yielding the best cost advantage.
