Sealing rings are designed as contact seals. They protect the bearing position against contaminants, spray water and excessive loss of grease.
The sealing rings are matched to the small radial dimensions of drawn cup needle roller bearings and needle roller bearings. They are very easy to fit, since they are simply pressed into the housing bore.
Sealing rings allow circumferential speeds at the seal lip of up to 10 m/s, dependent on the surface quality of the shaft. |
