This is a double row deep groove ball bearing with a bore diameter of 25.0 mm, outside diameter of 52.0 mm, and width of 18.0 mm. Net mass is 0.156 kg. The bearing uses a TVH cage made of glass-fiber reinforced plastic, which reduces friction and mass compared to a solid cage design. Radial internal clearance is in the CN (Group N) group. Limiting speed is rated at 13100 1/min, with a reference speed of 11200 1/min. The double row design allows this bearing to carry higher radial loads and moderate axial loads in both directions compared to a single row bearing of the same envelope size. The plastic cage geometry supports smooth ball guidance at the stated speed ratings and contributes to lower operating temperature during continuous rotation. Standard CN clearance makes this bearing suitable for general mounting conditions without preload, provided fits and shaft tolerances follow standard recommendations. The bearing is supplied open, without an integrated seal, so lubricant supply and contamination protection must be arranged in the housing design.
