This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore diameter of 45.0 mm, outside diameter of 75.0 mm, and width of 16.0 mm. Net mass is 0.247 kg. The cage is a steel sheet metal design (JN), and the bearing is built to C3 internal clearance, giving increased internal play to compensate for operating temperature rise and interference fits. Limiting speed is 13100 1/min, with a reference speed of 9800 1/min. The C3 clearance class makes this bearing suitable for applications where shaft and housing tolerances or thermal expansion would otherwise tighten the fit and reduce running clearance. The steel sheet metal cage keeps mass low and allows stable ball guidance at the stated speed ratings. As supplied, the bearing is open (bore type Z designation relates to the bore/ring finish per producer coding), so lubrication and sealing must be provided externally, and grease or oil selection should account for the speed and clearance values given above.
