Timken 22218KCJW33 Spherical Roller Bearing

Description

The Timken 22218KCJW33 is a high-performance spherical roller bearing designed for reliability in demanding industrial environments. It features two rows of rollers, a common sphered outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. This design allows the bearing to accommodate misalignment and handle heavy radial and axial loads. The tapered bore allows for mounting on a tapered journal or using an adapter sleeve.

FAQ

What is the significance of the 'K' and 'W33' suffixes in the part number 22218KCJW33?

The 'K' indicates that the bearing has a tapered bore with a standard taper of 1:12. This allows for mounting on a tapered shaft or with an adapter sleeve for a cylindrical shaft. The 'W33' suffix signifies that the bearing has a lubrication groove and three lubrication holes in the outer ring to facilitate efficient relubrication.

Mounting a tapered bore bearing involves driving it up the tapered seat to achieve the correct internal clearance reduction. This is typically done using a hydraulic nut or by carefully measuring the axial drive-up distance. It is crucial to follow the manufacturer's guidelines to avoid damaging the bearing or achieving incorrect preload.

Yes, the Timken 22218KCJW33 is suitable for both oil and grease lubrication. The choice depends on the application's operating speed, temperature, and load conditions. The W33 feature makes it particularly easy to relubricate with grease while in service.
