1,113,291. Bearings; swivel joint pipes. FMC CORPORATION. 20 Sept., 1965 [23 Oct., 1964], No. 39952/65. Headings F2A and F2G. A rolling bearing, particularly for a pipe joint, comprises an inner race 60 resiliently diametrically expandable before assembly, and an outer race 62 resiliently diametrically contractible before assembly. The inner and outer races are fitted in grooves in members 18, 16 and remain respectively in tension and compression. The races are each split at one place. A projection locates the inner race on the member 18. A cap 45 has a resilient end portion 52 with channels for the balls between the spaced ends of the outer race. Grease is introduced from fitting 56 and retained by seals. The materials of the races 60, 62 and members 18, 16 may be chosen to maintain constant clearance during temperature changes. |
