Notes about B....Sa Series :
These bearings are engineered to handle heavy one-directional thrust loads as well as combined radial and thrust loads. They come standard with elliptical lubrication grooves for enhanced performance and are available in both inch and metric sizes.

Other salient points to be noted :
• All dimensions apply before MoS2 coating.
• For bearings with grooves extended to the face of the outer ring at two places, add suffix “-1”, e.g. MB50SA-1
