This deep groove ball bearing carries radial and moderate axial loads in a single row of balls guided by a solid brass cage (M). Bore diameter is 80.0 mm, outside diameter 125.0 mm, width 22.0 mm, and mass is 0.84 kg. The limiting speed is rated at 9700 1/min, with a reference speed of 6100 1/min, reflecting the thermal and mechanical limits of the design. Internal clearance is C3 (Group 3), giving increased radial play to compensate for thermal expansion and interference fits under load. The solid brass cage (M) supports stable ball guidance at higher speeds and temperatures compared to pressed cage designs. Bore type Z should be checked against the specific tolerance requirements of the shaft seat during mounting. The bearing is supplied without integrated sealing, so lubrication and contamination protection must be provided externally.
