self-aligning bearing unit / bell-shaped / ball bearing / steel
steel, cast iron
Pillow block bearing pedestal type UCP
Housing, grey cast iron.
Bearing, ball-bearing steel 100Cr6.
Seal, rubber NBR.
Pillow block bearings consist of a sealed single-row ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with h-tolerances. The shaft is secured by grub screws on the inner ring.
In normal applications, pillow block bearings are maintenance-free due to the lifetime lubrication. In difficult environmental conditions re-lubrication can be carried out over the grease nipple.
All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration.
