SKF flanged bearing unit useful information
SKF flanged ball bearings are able to accommodate static misalignment by tilting the housing. When using pressed steel housings, the misalignment must be set before the attachment bolts have been fully tightened as it cannot be accommodated once tightened unless a rubber seating ring is also used.
For cast iron, stainless steel or composite material housings, the load ratings of the flanged bearing units is at least equal to the individual insert bearing loads. For pressed steel bearing units, the load ratings are less than the individual SKF insert bearings. You should check the load rating of the pressed steel bearing units on the specification sheet before selecting them for use.
