Monton Bearing can supply the customized bearings according to the request.

We have developed one thin section angular contact ball bearings with the dimension 10*15*2.5mm.This bearings are made with special stainless stell material with non-magnatic performance and with P4 accuracy.The width is only 4mm,with 1mm special ball.We have realize batch production for this kinds bearings and now the bearings have been widely used in Russia,iran or USA on the missle.
