Description

Carries axial loads acting in both directions along the shaft while locating the shaft axially in one bearing position, thanks to the double-direction design mounted directly by screws. Bore diameter is 260.0 mm, height 55.0 mm, net mass 18.4 kg, and the limiting speed reaches 2400.0 1/min. Sealing shields are fitted on both sides of the bearing. The screw-mounting arrangement allows precise axial preload and rigid location without a separate housing seat, making the bearing suitable where axial positioning accuracy and stiffness under combined axial loading are required. The integrated shields on both faces restrict ingress of contaminants into the raceway area, which supports stable running behaviour at the given limiting speed without additional external sealing.
