• Common 4-bolt flange bearing housings are F200 (standard duty), FX (medium duty), F300 (heavty duty),  higher central height FS200 (standard duty), and FS300 (heavty duty) as welll.

• Standard painting in green color (other colors are available for choices).

• End cap by pressed steel are capable of protecting against 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 are locked onto the shaft by means of set screws, eccentric locking collars, adapter sleeves, and concentric locking collars etc.
