This bearing housing carries a radial insert ball bearing with an eccentric locking collar, mounted in a cast iron take-up housing. Bore diameter is 20.0 mm, mass is 0.39 kg, and the basic dynamic load rating is 13600.0 N. The unit is fitted with P seals to protect the bearing insert from contamination. The eccentric locking collar allows secure fixation of the inner ring on the shaft without set screws, while the take-up housing design permits axial adjustment of the unit along mounting rails, compensating for belt or chain tension changes. The P seals provide protection against dust and moisture ingress, making the unit suitable for applications requiring positional adjustment combined with reliable sealing at the specified load rating.
