This spindle bearing carries a 25° contact angle and ceramic balls, running in a bore diameter of 45.0 mm, outside diameter of 75.0 mm and width of 16.0 mm, with a net mass of 0.247 kg. The cage is executed in version T, and sealing is provided by non-contact lip seals on both sides (2RSD), keeping the rolling elements free of contact drag at speed. Supplied as adjusted bearings for mounting in pairs or sets, this design suits arrangements requiring restricted tolerances and precise axial positioning under high rotational speed. The ceramic balls reduce centrifugal loading on the outer ring at speed, while the non-contact sealing limits friction and heat generation, and the P4S accuracy class supports applications where running precision and low vibration are required.
