3 Bolt Flange Mounted Bearings

Name: 3 Bolt Flange Mounted Bearings
Rating: 5 (99 reviews)

3-bolt flange mounted bearings are the combinations of 3-bolts flange bearing housings and wider inner ring ball bearings.
Common 3-bolt flange bearing housings are FB200 (standard duty) and FCT200 (light duty by ductile iron).
End cover by pressed steel are capable of protecting against the external polution and dusts.
The self-aligning ability of the ball bearings can compensate for slight static mis-alignemnt of the shaft. The bearing inserts of are locked onto the shaft by means of set screws and eccentric locking collars etc.
Lubricants filled inside the spherical ball bearing inserts can be standard grease, low/hight temperature grease and food grade grease.
