NSK 2210KC3 Self-Aligning Ball Bearing

Description

The NSK 2210KC3 is a high-quality self-aligning ball bearing designed for industrial applications where static or dynamic misalignment can occur. Its spherical outer ring raceway allows the inner ring, balls, and cage to rotate freely around the bearing center, compensating for shaft deflection and housing alignment errors. This bearing features a tapered bore for mounting with an adapter sleeve and C3 internal clearance for applications with higher speeds or temperature variations.

FAQ

What is the significance of the 'K' and 'C3' suffixes in the 2210KC3 model number?

The 'K' suffix indicates that the bearing has a tapered bore with a 1:12 taper, designed for mounting on a shaft using an adapter or withdrawal sleeve. The 'C3' suffix signifies that the bearing has an internal radial clearance greater than the 'Normal' (CN) clearance, which is suitable for applications with temperature differences between the inner and outer rings or for higher-speed operations.

A bearing with a 2210K designation (50mm bore) typically requires an H310 adapter sleeve for mounting on a cylindrical shaft. Always consult the manufacturer's mounting instructions to ensure the correct sleeve and locknut combination is used for your specific application.

Yes, the C3 clearance makes this bearing more suitable for high-temperature applications than a standard clearance bearing. The extra clearance accommodates thermal expansion of the bearing components, preventing excessive preload and potential premature failure. However, for continuous operation above 120 deg C, special heat stabilization treatments and lubricants may be required.
