Overview
Material: GCR15 Bearing Steel. Friction reduction: The use of GCR15 steel and precision engineering results in reduced friction, allowing for smooth and efficient operation. Rubber sealed (2RS) bearings are better sealed and can be dustproof and dirt-proof, but they are more frictional and have a lower rotational speed than steel sealed bearings.
