SKF Cooper split roller bearings and bearing units

Sealing As hanger housings do not have cartridges, the seals are mounted directly into the hous- ing. The housing can accommodate: • double felt seals, as standard • rubber lip or high temperature packing seals, on request Alternative seals, for example heavy-duty lip seals ( fig. 2 ), are available on request and require a housing with different machining.

Lubrication Lubrication points are not fitted to hangers as standard, with provision for lubrication of the bearing usually made through the sus- pension rod. Continuous grease lubrication is sometimes desirable. Grease purging SKF can supply the housings with tapped holes that lead into the space between the seal grooves at each end of the housing ( fig. 2 , designation suffix AP). This is for con- nection to either a grease supply or an air supply for regular or continuous purging of the seals. 161 6
