Permissible angular misalignment
Depending on their series and size, SKF
self-aligning ball bearings are itted with one
of the cages shown in table 4.
When used at high temperatures, some
lubricants can have a detrimental effect on α
polyamide cages. For additional information
about the suitability of cages, refer to Cages,
