Features They can sustain radial loads mainly and can also sustain some axial load in either direction. The bearings have low friction and very little noise or vibration, These characteristics make them to be available for situations of high speed, high precision, low friction and low noise operations.
Application Radial ball bearings are engineered for use in high-speed, high precision applications for: Agriculture, Automotive, Chemical, General industrial, Utilities.
Package pallet, wooden case,industrial package or as customers' requirement
Price FOB, CFR, CIF Delivery Time 5-10 days



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.
