Designs

These bearings are combined cylindrical roller radial/thrust bearings. They consist of one one-piece and one two-piece ring as well as two roller sets to accommodate axial loads, and one roller set to accommodate radial loads. Polyamide cages separate the axially loaded rollers. The bearings are not preloaded and have integral lip seals.
