P0 Chrome Steel Gcr15 Precision Ball Bearing 20*52*15mm 6304 2RS For Conveyor Roller
I. Product brief introduction:
Conveyor roller had several layers of nylon roller bearing seal protection, sealed performance is good, bearing and seal to reinvent the wheel, open type roller bearing convenient installation themselves according to the actual situation before mastering roller bearing lubrication oil filling quantity.
We using standard chrome steel GCR15, AISI52100 to prepare our rings, G10,G16 grade bearing balls.
Both inner and outer ring groove has to be polished to guarantee bearing movement more fluent and low noise.
Our bearing work life more longer then ordinary bearings, because our polish working time is longer then market normal level.
II. Product advantage:
Full lubricated, guarantee long work hour. ( See the bottom picture shows )
Competitive price and quite stable quality;
Large stock rings, fast delivery guranteed.
III. Product applicant:
Mainly used in conveyor rollers in normal precision grade.
Higher precision used in engine bearing, motorcycle front wheel, electric motors.
