a segmented roller clutch cage is comprised of loose jointed modules that combine good clutch race conformance with easy assembly , as well as allowing for selective module disassembly axial parting motion . each of a plurality of separately molded elements is joined to the next with identical male and female fasteners that fit together with a simple straight line push , along the cage axis . a slide and rail combination on one end of each module fits into matching grooves on the other end of each module . the grooves are created by undercut , radially opposed beam pairs , the radially outboard one of which is more flexible . a barb on the slide - rail unit is designed to snap or latch past the flexible beam . the slide and rail fit into the grooves with enough clearance to give freely expanding and contracting joints , so that between race conformance is very good . the joints may even be disassembled with a compound radial bending and axial parting motion .
