FIELD: mechanical engineering, in particular, equipment used under increased sliding speed conditions and high radial loading in nonrecoil units. SUBSTANCE: combined support has at least one roller bearing mounted in casing and at least one slider bearing made in the form of floating bush. Bearings are successively arranged in axially aligned relation. Combined support is further provided with shaft journal and lubricant supply and discharge channels. Floating bush has at least one cylindrical end projection provided with lubricant entry opening and lubricant baffle made in the form of radial projection. Roller bearing is positioned in spaced relation on shaft journal. End projection of floating bush is arranged in this space and lubricant baffle is disposed between end surfaces of casing and roller bearing. Lubricant opening in floating bush is disposed between its middle portion and lubricant baffle. Support has auxiliary bush rigidly connected with shaft and enclosed in casing. Insert is attached to casing in zone below auxiliary bush. Electrical flocculated nonwoven fabric is attached to casing surface, with piles of fabric being inclined to working surface. EFFECT: increased efficiency of combined support by providing variation in resistance moment value depending on shaft rotation direction, wider operational capabilities and enhanced reliability in operation. 1 dwg
