LIPPED WIPER SEALS WITH INTEGRAL RETAINING RING:
PDF Catalogue of Linear Bearings
These seal rings are made from rubber inserted into a metal casing. This special design ensures the steel locates perfectly in the housing bore without any other retaining facility.

A number of factors have to be considered when selecting supplementary seals, for instance, the arrangement, design or available space. This V-section seal consists of two wipers and performs two purposes. The inner wiper retains the lubricant in the bushing and the outer wiper protects the ball bushing against the ingress of particles. Bellows type covers should be fitted over the shafts if the operating environment is very dirty / dusty. |
