FAQ

What does the ‘RS1’ suffix mean on the SKF 6204-RS1 bearing?

The ‘RS1’ designation indicates that the bearing is fitted with a sheet steel reinforced contact seal made of Acrylonitrile-butadiene rubber (NBR) on one side. This seal provides excellent protection against contaminants and helps retain lubricant.

Is this 1984 bearing still usable, and what should I check before installation?

Yes, as New Old Stock (NOS), this bearing is typically perfectly usable. Before installation, visually inspect it for any signs of corrosion or hardened grease. Rotate the inner ring by hand to ensure it moves smoothly without any grittiness or binding. If it feels smooth, it is ready for use.

Can I use this single-sealed 6204-RS1 bearing to replace a double-sealed (2RS1) bearing?

It depends on the application. An RS1 bearing is open on one side. If you replace a 2RS1 (sealed on both sides) bearing, the open side of this RS1 bearing will be exposed. This is only acceptable if that side is fully enclosed within a clean, lubricated environment like an oil bath or sealed gearbox.
