FAQ

The 'SS' stands for Stainless Steel. This material provides superior corrosion resistance compared to standard chrome steel, making the bearing suitable for use in humid, wet, or mildly corrosive environments without the risk of rust.

The flange on the outer ring acts as a shoulder, allowing the bearing to be located axially in a housing bore with a simple through-hole. This simplifies the mounting process, ensures precise positioning, and prevents the bearing from being pushed through the housing under axial load.

This '2Z' bearing has non-contact metal shields on both sides, which offer good protection against larger contaminants and have very low friction, making them ideal for high-speed applications. A '2RS' bearing, in contrast, uses rubber seals that make contact with the inner ring, providing excellent protection against fine dust and moisture but with slightly higher friction and lower maximum speed limits.
