FAQ

Question?

What does the ‘2RS1’ suffix mean on an SKF bearing?

The ‘2RS1’ suffix indicates that the bearing is equipped with a contact seal made of NBR (nitrile butadiene rubber) on both sides. These seals provide excellent protection against contamination and moisture, while retaining the lubricant.

Question?

Is this 61901-2RS1 bearing suitable for high-speed applications?

The 61901-2RS1 is part of the 619 series, which are extra thin section bearings. While they can handle moderate speeds, the contact seals (RS1) generate more friction than non-contact seals (2Z). For very high-speed applications, consult SKF’s limiting speed specifications and consider a bearing with low-friction seals.

Question?

Can I use a different type of grease with this bearing?

SKF 61901-2RS1 bearings are supplied pre-lubricated with a specific high-quality grease. It is not recommended to wash out the original grease or mix it with another type, as this can compromise bearing performance and lifespan.
