OTS’s ceramic ball bearing cartridge  for performance turbocharger has been recognized by the market and we keep receiving repeat orders. The material we currently apply for the ball bearing cages is VICTREX PEEK polymers imported from UK. Though compared to traditional copper cages, PEEK cages have the advantages of suitable for high speed & temperature, good lubrication & stability as well as light weight, many of our customers are still looking for metal cages.

Furtunately, new development has achieved, below pictures show the new developped metal cage. It is produced from certain special nickel-containing metal material, which improves high temperature resistance of the cage. Also, a layer of silver coating improves the lubricity. It is now at the stage of testing, we have shipped a batch of ball bearings with this kind of metal cages to our customers for testing. Any friend who is interested in our new development, welcome to follow us for further updates.
