NSK 2216KC3 Self-Aligning Ball Bearing

Description

The NSK 2216KC3 is a high-performance self-aligning ball bearing designed to accommodate misalignment between the shaft and housing. It features two rows of balls and a common sphered raceway in the outer ring, allowing for angular adjustments. This specific model includes a tapered bore for mounting with an adapter sleeve and C3 internal clearance, which is suitable for applications with higher speeds or temperature variations.

FAQ

The 'K' indicates a tapered bore (1:12 taper), which requires an adapter sleeve for mounting on a cylindrical shaft. The 'C3' denotes an internal radial clearance that is greater than 'Normal', making it suitable for applications involving high speeds, temperature gradients, or interference fits.

For a shaft diameter of 75mm, the recommended adapter sleeve is an H316. Always verify the correct sleeve for your specific shaft size according to the manufacturer's handbook.

While the C3 clearance itself does not dictate a specific lubricant, the application's operating speed and temperature do. It is crucial to select a grease or oil that matches the operational parameters (DN value) to ensure optimal performance and bearing life.
