FAQ

What is the significance of the 'K' in the 22310KEJW33 part number?
The 'K' suffix indicates that the bearing has a tapered bore, with a standard taper of 1:12. This design allows for mounting on a tapered shaft journal or on a cylindrical shaft using an adapter or withdrawal sleeve, providing a tight interference fit.

Can I use grease or oil for lubricating this W33 bearing?
Yes, the W33 designation, which refers to the lubrication groove and holes in the outer ring, facilitates effective relubrication with either grease or oil. The choice depends on the specific application's operating speed, temperature, and load conditions.

What is the correct mounting procedure for a bearing with a tapered bore?
Mounting a tapered bore bearing involves driving it up the tapered seat. The correct fit is achieved not by torque, but by measuring the reduction in radial internal clearance. Using feeler gauges to monitor this reduction is critical to prevent overloading the bearing upon installation.
