This unit locates and supports a shaft through a cast iron take-up bearing housing designed for linear motion adjustment along mounting rails. The insert ball bearing has a bore diameter of 70.0 mm and is secured to the shaft with grub screws in the inner ring, allowing axial positioning within the housing before final tightening. Overall height is 167.0 mm, net mass 6.677 kg, and the basic dynamic load rating is 66000.0 N. RSR seals on both sides of the bearing protect the rolling elements from dust and moisture while retaining grease inside the unit. The grub screw fixation combined with the take-up housing design suits applications where belt or chain tension needs periodic adjustment, since the housing permits shifting the bearing position without dismounting the shaft. The spherical outer ring surface of the insert bearing allows a degree of self-alignment, accommodating minor shaft misalignment during operation.
