This single row deep groove ball bearing carries a bore diameter of 40.0 mm, outside diameter of 90.0 mm, and width of 23.0 mm, with a net mass of 0.611 kg. It uses a steel sheet metal cage (JN) and features C3 radial internal clearance (Group 3), which provides greater internal clearance than standard to compensate for thermal expansion during operation. Limiting speed is rated at 10800.0 1/min, with a reference speed of 9000.0 1/min. The C3 clearance class makes this bearing suitable for applications where operating temperatures raise the effective fit between inner ring, balls, and outer ring, allowing the increased internal clearance to prevent excessive preload. The single row deep groove design accommodates both radial loads and moderate axial loads in either direction. Equivalent references for this bearing include SKF 6308/C3, NSK 6308C3, and NTN 6308C3.
