This bearing housing carries a radial insert ball bearing set inside a cast iron take-up housing, designed for adjustable positioning along linear guide rails. The inner ring is secured to the shaft by grub screws, giving a bore diameter of 60.0 mm, while RSR seals on both sides protect the bearing from dust and moisture ingress. Overall height is 146.0 mm, net mass is 4.7 kg, and the basic dynamic load rating reaches 56000.0 N. The sliding base design allows the whole unit to move within the housing frame, making it suitable for applications requiring belt or chain tensioning through linear adjustment of the shaft position. The self-aligning insert bearing accommodates minor shaft misalignment, while the grub screw fixation ensures a solid connection without additional locking elements. The RSR seal arrangement supports operation under grease lubrication in environments where contamination protection is required.
