Bearing Units Introduction

FK ball bearing units provide simple and effective bearing arrangements capable of accommodating moderate initial misalignment from mounting errors. They are easily mounted onto commercial shafting and are particularly useful where fabricated machine frames are employed. 
Bearing Units
The units are available in a variety of pillow block, flange, cartridge and take-up mounted configurations with one piece of cast iron, ductile iron, stainless steel, thermoplastic or two pressed steel housings. 

There are many different combinations of insert bearings and housings. 

FK inserts are wide inner ring ball bearings that are effectively and efficiently sealed, including J type rubber seal, H type metal shield seal, SL type dual seal, L3 type triple seal, F type combine seal, dust cap and end-cover. 

Simple fitting onto standard shafting is provided for by means of eccentric locking collar, set screws, adapter sleeve or squeeze lock. 

The reliability, simplicity and ease of assembly of items in the FK ball bearing units range has resulted in their popularity in application areas of agricultural, extraction machinery, textile machinery, parking equipment, fan equipment and construction machinery as well as process and automation equipment.
