FAG 2218K C3 Self-Aligning Ball Bearing

Description

This FAG 2218K C3 is a premium self-aligning ball bearing designed for applications where shaft deflection or mounting misalignments are expected. Its dual-row design and sphered outer ring raceway allow it to operate smoothly even with angular misalignments. The tapered bore facilitates easy mounting using an adapter sleeve. This bearing is New Old Stock (NOS), offering the performance of a new part.

FAQ

The 'K' suffix indicates that the bearing has a tapered bore with a taper of 1:12. This design requires mounting on a shaft using an adapter sleeve (e.g., H318) or on a tapered shaft journal.

The C3 radial internal clearance is greater than the 'Normal' (CN) clearance. This extra space is crucial in applications where there's a significant temperature difference between the inner and outer rings, or in high-speed applications, as it prevents the bearing from seizing due to thermal expansion.

Yes, the sphered raceway in the outer ring allows the inner ring, balls, and cage to rotate freely and align themselves relative to the outer ring. It can compensate for initial static misalignment from mounting errors as well as dynamic misalignment that occurs during operation.
