NSK 2212K

NSK 2212K Self-Aligning Ball Bearing

Description

The NSK 2212K is a high-performance self-aligning ball bearing designed to accommodate misalignment and shaft deflection. Featuring two rows of balls and a common sphered raceway in the outer ring, this bearing is capable of self-alignment, which reduces stress on the bearing and increases service life. The ‘K’ suffix signifies a tapered bore, allowing for secure mounting with an adapter sleeve.

FAQ

Question?

What is the significance of the ‘K’ suffix in the 2212K model number?

The ‘K’ indicates that the bearing has a tapered bore with a standard taper of 1:12. This design allows for mounting on a cylindrical shaft using an adapter sleeve (e.g., H312) or on a tapered shaft, ensuring a tight interference fit.

Question?

Can this self-aligning ball bearing handle axial loads?

Yes, self-aligning ball bearings like the NSK 2212K can accommodate axial loads in both directions. However, their primary strength is handling radial loads and static or dynamic misalignment. For heavy axial loads, a thrust bearing would be more suitable.

Question?

What kind of lubrication is recommended for the 2212K bearing?

This bearing is typically open (not sealed) and requires external lubrication. It can be lubricated with either grease or oil, depending on the operational speed, load, and temperature. Always consult the machine’s maintenance manual for the specific lubricant type and relubrication interval.
