This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running on a solid laminated fabric cage (TB). The bore diameter is 40.0 mm, outside diameter 80.0 mm, width 18.0 mm, and net mass 0.37 kg. The limiting speed reaches 12300 1/min, with a reference speed of 9300 1/min, giving a good margin for sustained running conditions. Radial internal clearance is C3 (Group 3), which is wider than standard and compensates for thermal expansion or interference fits that would otherwise tighten the clearance during operation. The solid laminated fabric cage (TB) offers stable ball guidance and reduced friction at higher speeds. Bore type Z indicates the specific bore tolerance configuration. This combination of C3 clearance and the TB cage design makes the bearing suitable for applications where elevated operating temperatures or tighter mounting fits require additional internal clearance margin.
