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.

Character:

Dimension:10х15х2,5 mm

Accuracy:High precision

Material:Special Non-Magantic stainless steel

Application:Missile

In the same time:

Monton bearings can also supply other kinds special missile bearings from 2mm~100mm including the non-standard deep groove ball bearings,the non-standard angular contact ball bearings and the non-stand cylindrical roller bearings,ect.
