SEALED BEARINGS
The sealed drawn cup bearings are offered with integral seals. The seal lip design achieves a light and constant contact with the inner raceway throughoutthe range of mounted bearing clearances thereby ensuring positive sealing and low frictional drag.
Sealed drawn cup bearings are intended to retain grease or non-pressurized oil within a bearing while also preventing contaminants entering the raceway area.
The standard lip contact seals are compatible with common lubricating oils and petroleum based fuels, but they are adversely affected by certain fire-resistant hydraulic fluids and mostcommonsolvents. Sealed drawn cup bearings are normally filled with a high quality lithium soap base general purpose grease. The sealmaterial and grease properties limit the bearing operating temperature between-30°C and+100°C.
Ifthe operating temperature must be outside of the range for the seals mentioned here, or if the seals are exposed to unusual fluids please consult your Zhihua automotive representative.
