GR type cartridges accommodate locating (GR type) SKF Cooper split cylindrical roller bearings. They provide a swivel seating between the bearing and the outer housing (which may be of plummer block, flanged or other type) to allow for static misalignment between the shaft and outer housing. Cartridges also house seals. The swivel seating allows these seals to be maintained in accurate concentricity to the shaft for reliable sealing. GR type cartridges use axial screws to clamp the bearing outer ring.
