This bearing housing unit locates a radial insert ball bearing with a cast iron housing on a long base, giving a bore diameter of 20.0 mm, width of 31.0 mm and height of 65.0 mm. Net mass is 0.69 kg, and the basic dynamic load rating reaches 13600.0 N. The inner ring is secured to the shaft with grub screws, and RSR seals protect the bearing from contamination. The grub screw fixation allows quick mounting directly on the shaft without additional locking elements, while the long base simplifies alignment and bolting to the supporting structure. RSR seals retain grease and keep dust and moisture out of the bearing, supporting stable operation under the stated load rating without frequent maintenance.
