FAQ

Question?

What does the ‘2RS1’ designation mean on this SKF bearing?

Answer?

The ‘2RS1’ suffix indicates that the bearing is sealed on both sides (‘2’). The seal itself (‘RS1’) is a sheet steel reinforced contact seal made of Acrylonitrile-butadiene rubber (NBR), providing excellent protection against dust, dirt, and moisture ingress.

Question?

Why is the ‘C3’ clearance important for my application?

Answer?

The ‘C3’ indicates that the bearing has an internal radial clearance that is greater than ‘Normal’. This extra clearance is necessary in applications with high rotational speeds, significant temperature gradients between the inner and outer rings, or where a press fit is used on both rings, as it accommodates thermal expansion and prevents bearing seizure.

Question?

Can I use a different grease with this 6310-2RS1/C3 bearing?

Answer?

This bearing comes pre-lubricated from the factory with a high-quality grease designed for a wide range of operating conditions. The RS1 seals are designed to retain this grease for the life of the bearing. It is not recommended to attempt to wash out the factory grease and relubricate it, as this can damage the seals and introduce contaminants.
