This bearing housing unit combines a cast iron split housing with a radial insert ball bearing locked onto the shaft by grub screws in the inner ring. Bore diameter is 55.0 mm, width 55.6 mm, height 124.5 mm, net mass 3.22 kg, and the basic dynamic load rating reaches 46000.0 N. The bearing is fitted with R seals on both sides. The grub screw fixation allows quick mounting directly on the shaft without an adapter sleeve, while the cast iron housing carries the radial load stated above through the plummer block base. The R seals restrict the ingress of dust and moisture into the bearing cavity, keeping the grease inside the housing during operation. The insert bearing design permits limited shaft misalignment within the housing bore, simplifying alignment during installation.
