This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 85.0 mm, outside diameter of 180.0 mm and width of 41.0 mm. It features metal shields on both sides and a steel sheet metal cage (JN), giving a net mass of 4.36 kg. The limiting speed is 4300 1/min and the reference speed 5300 1/min, with radial internal clearance in group CN. The metal shields protect the raceway from dust while allowing grease retained inside to remain in the bearing, so it is suited to applications requiring shielded, low-maintenance operation without contact seal friction. Standard CN clearance matches shaft and housing fits under normal load and temperature conditions, making this bearing a direct dimensional match for SKF 6317-2Z, NSK 6317ZZ and NTN 6317ZZ.
