This bearing housing carries a bore diameter of 50.0 mm and combines a cast iron four-bolt flanged housing with an insert bearing secured by grub screws in the inner ring. Net mass is 2.44 kg, width is 51.6 mm, and the basic dynamic load rating reaches 37500.0 N. R seals protect the insert bearing against contamination while retaining lubricant inside the unit. The four-bolt flange design allows mounting through the housing face, and the grub screw fixation on the inner ring provides a positive lock onto the shaft, suitable for applications where the shaft is fixed axially at the bearing position. The cast iron housing body supports the stated dynamic load rating under steady operating conditions, while the R seal arrangement is intended for environments where basic protection against dust and moisture ingress is required.
