SWP universal coupling, the cross shaft bearing seat for the split, is to consider the bearing is the wear parts of the universal coupling, the bearing gland made into split, is to facilitate the replacement of bearings. But gland bolts loosen easily. According to the structure of the intermediate shaft and shaft fork connection form is different, A total of seven kinds of style: SWP type A (with telescopic type) cross shaft universal coupling, type B - scale short form universal coupling, C - no scale short form universal coupling, D - non-stretch type universal coupling, E - has flexible double flange type universal coupling, F type, large scale type universal coupling, type G - scale ultra short form universal coupling.
