This unit accommodates a radial insert ball bearing with a cast iron take-up housing, locked onto the shaft by grub screws in the inner ring. Bore diameter is 17.0 mm, net mass 420.0 g, and the basic dynamic load rating reaches 13600.0 N. RSR seals protect the bearing from contamination on both sides. The take-up design allows the housing to slide within a mounting frame, which supports belt tensioning and shaft position adjustment along the slot. Grub screw fixation permits quick mounting without requiring a stepped or tapered shaft seat. The RSR sealing arrangement suits applications where moderate protection against dust and moisture is needed, while the spherical outer ring surface of the bearing insert compensates for minor shaft misalignment during operation.
