This deep groove ball bearing carries radial and moderate axial loads in a single row of balls guided by a steel sheet metal cage (JN). Bore diameter is 45.0 mm, outside diameter 75.0 mm, width 16.0 mm, and net mass is 0.24 kg. Both sides are fitted with seals (2RSR), and the limiting speed is 4950 1/min. Radial internal clearance corresponds to C3 (Group 3), wider than standard clearance. The C3 internal clearance compensates for temperature rise and interference fit effects during operation, keeping the bearing free of excessive preload after mounting. The seals on both sides retain grease inside the bearing and block dirt and moisture ingress, so the unit runs pre-lubricated and does not require external grease replenishment under normal conditions. Dimensional equivalents are SKF 6009-2RS1/C3, NSK 6009DDUC3, and NTN 6009LLUC3.
