This single row deep groove ball bearing carries the bore diameter of 25.0 mm, outside diameter of 52.0 mm and width of 15.0 mm, with a net mass of 0.124 kg. It is fitted with a solid laminated fabric cage (TB) and radial internal clearance C3, in accuracy class P6. The limiting speed is 19700 1/min, with a reference speed of 14500 1/min. The P6 accuracy class allows tighter running tolerances than standard, while the C3 clearance accommodates thermal expansion under load, keeping the bearing suitable for applications with elevated operating temperatures or interference fits. The TB cage construction supports stable ball guidance at the stated speed range, and as an open bearing without integrated sealing, it requires external lubrication and protection appropriate to the operating environment.
