Product Description

Parameters

Cylindrical roller bearings can be lubricated with either grease or oil. Double row bearings feature a lubricating groove and lubricating hole in the middle of the outer ring.

Due to the line contact in between rolling elements and raceways, CHIK cylindrical roller bearings have higher radial load capacity and they are suited to high-speed applications due to their structure.                                            
Having a separable inner or outer ring, these bearings can be easily mounted and dismounted.
