Designs and variants
Depending on their series and size, SKF spherical roller thrust bearings are manufactured to two basic designs. Their cage forms a non-separable unit with the shaft washer and rollers.
Bearings with no designation suffix (e.g. 29272)
are fitted with a machined brass prong-type cage as standard (fig. 1)
E design bearings (designation suffix E)
Cages in SKF spherical roller thrust bearings are an integral part of the bearing internal design. All SKF spherical roller thrust bearings contain a strong metal cage. This enables them to tolerate high temperatures and operate with all lubricants.
For additional information about the suitability of cages, refer to Cages.
