This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore diameter of 17.0 mm, outside diameter of 40.0 mm, and width of 12.0 mm. Net mass is 0.065 kg. The bearing uses a solid laminated fabric cage (TB) and is built to P6 accuracy class with C3 internal clearance, providing extra internal play to offset thermal expansion during operation. Limiting speed is rated at 26500 1/min, with a reference speed of 18100 1/min. The P6 accuracy class supports applications requiring tighter running tolerances and reduced radial runout compared to standard tolerance bearings. The C3 clearance compensates for interference fits and heat generated at higher speeds, keeping internal play within a suitable working range under load. The laminated fabric cage offers stable ball guidance at elevated speeds while keeping operating temperature low. As an open bearing (no seals or shields), lubrication must be supplied and maintained externally, and the bore type Z should be checked against the mounting shaft tolerance before assembly.
