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 :
• Bore dimensions are after MoS2 coating. All other dimensions are before coating.
• For bearings with grooves extended to the face of the outer ring at two places, add suffix “-1”, e.g. B32SA-1
• Ultimate static and impact loads should not exceed 150% of catalog ratings.
