ABSTRACT:
A roller or wheel of the type in question has rolling bearings (5) which must be pre-loaded; a unit and relative method of assembly as disclosed offers simple fitment of component parts, accurate pre-load, and economy of manufacture. The two bearings (5) are checked axially by external limiting means (9) and internal limiting means (8); the method of assembly features a step of compacting the component parts axially to the point where the reaction produced by the parts thus urged together offsets the applied compacting force, and a subsequent step of spreading the external limiting means (9) in such a way as to arrive at the requisite bearing pre-load.
