Utekhin The device known a.s a hydraulic nut [1], consisting of a steel ring with a blind cylindrical recess on one face, accommodating a piston of annular shape, is frequently used in the assembly and disassembly of large bearings (i. d. larger than 150 mm). O-ring seals form a leaktight joint between the steel ring and the piston. The hydraulic nut is threaded onto a shaft or tapered bushing and is held fast by end bolts or a spilt locking ring. Hydraulic fluid is fed to the piston of the hydraulic nut from a hydraulic pump to provide the axial thrust required to assemble or disassemble the bearings. Hydraulic nuts of the type described, termed ring hydraulic nuts by the author (since the forces gener- ated in them were transmitted via a ring-shaped piston) were used at the Izhevsk heavy papermaMng mach- inery plant for assembling bearing units in the dryer end of a model 462 papermaking machine, but their use was discontinued because of a number of defects in the tool. The lihevsk Mechanical Institute meanwhile has begun work at the plant on the design of a hydraulic nut which the author terms a plunger
