Bearings with a flanged outer ring
Certain sizes of SKF stainless steel deep groove ball bearings are also available with a flange on the outer ring (designation suffix R, fig. 1) and can be supplied open or capped (→ Sealing solutions). Bearings with a flanged outer ring are relatively easy to locate axially in the housing. The housing bore is also easier and more cost-effective to manufacture, as shoulders are not required.
