Application

This bearing is suitable for a wide range of applications, including gearboxes, wind turbines, continuous casting machines, pumps, fans, and heavy machinery where misalignment and heavy loads are a factor.

CO2 Impact

By purchasing this pre-owned bearing, you contribute to a circular economy and help avoid the emission of approximately 6.7 kg of CO2, which would have been generated during the production of a new unit. This saving is equivalent to the CO2 absorption of a mature tree over several months.

FAQ

What is the significance of the ‘K’ in the part number 22217EKJW33C3?

The ‘K’ indicates that the bearing has a tapered bore with a standard taper of 1:12. This design allows for mounting on a tapered shaft or on a cylindrical shaft using an adapter sleeve, providing a secure fit.

What does the ‘C3’ clearance mean and why is it important?

‘C3’ denotes an internal radial clearance that is greater than the ‘Normal’ (CN) clearance. This extra clearance is necessary in applications where there might be a tight interference fit or where significant temperature differences between the inner and outer rings are expected, preventing the bearing from seizing during operation.

Can this RHP bearing be used with oil lubrication?

Yes, the W33 feature (annular groove and three lubrication holes in the outer ring) makes this bearing ideal for both grease and oil lubrication. The groove allows lubricant to be introduced efficiently between the roller rows, which is crucial for high-speed or heavy-load applications requiring circulating oil lubrication.
