PCT No. PCT/US80/01071 Sec. 371 Date Aug. 18, 1980 Sec. 102(e) Date Aug. 18, 1980 PCT Filed Aug. 18, 1980 PCT Pub. No. WO82/00692 PCT Pub. Date Mar. 4, 1982.A self-aligning mounting structure (52) for preventing flaking of, for example, the uprights (16) on a lift truck includes a crowned spring (94) positioned between an axle shaft (76) and a bearing assembly (82) of a roller (22) to allow the roller (22) to maintain full face contact with the uprights (16). The crowned spring (94) additionally acts as a shock absorber to reduce the effect of impact loading. A snubber spring ring (106) can be positioned adjacent the crowned spring (94) to stiffen said crowned spring (94) and further reduce the effect of impact loading. With two or more mounting structures (52), crowned spring (94) allows a load sharing among the rollers (22).
