NSK Thrust ball bearings are composed of washer-like bearing rings with raceway grooves. Single-direction thrust ball bearings can sustain an axial load in only one direction.
Pressed cages are usually used, but larger ones are machined brass. The basic load ratings listed in the bearing tables are based on the standard cage type. If the type of cage is different for bearings with the same number, the number of balls may vary. In such a case, the load rating will differ from the one listed in the bearing tables.
Various part numbers in stock, welcome inquiry. Fast shipment within 2-3 working days.
