This unit combines a cast iron take-up housing with a radial insert ball bearing fixed to the shaft by grub screws in the inner ring. Bore diameter is 45.0 mm, net mass is 1.9 kg, and the basic dynamic load rating reaches 34500.0 N. RSR seals protect the bearing area from contamination. The slotted take-up design allows the bearing housing to be shifted along mounting rails, which is useful for adjusting belt tension or compensating for positional changes during assembly. The grub screw fixation and sealing arrangement suit applications with swivel motion, where the shaft position may vary and simple re-tightening of the inner ring is required rather than a fixed sleeve mounting.
