Cages
The main tasks of a cage are:
- separating the rolling elements, in order to keep friction and a hereby generated heat at the minimum
- keeping the same distance between rolling elements, in order to ensure an even load distribution and a smooth run
- guiding the rolling elements in the unloaded zone of the bearing
- preventing the rolling elements from falling out (in case of dismountable bearings)
The selection of different cage materials depends on several aspects: chemical reactions caused by the lubricant; operating temperature of the bearing, and loading of the cage.
This is why we offer you sheet metal cages and brass cages, the latter in different versions:
metal, plastic and hard tissue. The standard deep groove ball bearings have sheet metal cages. For special applications requiring cage materials other than the standard range, please contact our LFD engineers.
