Carries radial loads with a single row of balls running in a narrow-section 160-series raceway, bore 100.0 mm, outside diameter 150.0 mm, width only 16.0 mm, net mass 0.91 kg. The cage is a steel sheet metal design (JN), and internal clearance is set to C3 (Group 3), wider than standard. Limiting speed is rated at 6300 1/min, reference speed at 4000 1/min. The slim 16 mm width suits installations where axial space is restricted while still requiring a bore of 100 mm. The C3 clearance compensates for interference fits and thermal expansion during operation, keeping the bearing from running too tight under load. The steel sheet metal cage guides the balls with low mass and low friction at the stated speed ratings. Being open (bore type Z reference only, no seal or shield specified), the bearing depends on external sealing and a separate lubrication supply matched to the reference and limiting speed values given.
