HMV 150E-Hydraulic Nut
HMV: Hydraulic Nut, Metric; E: without slot;
include a spare set of piston seals and maintenance kit and a quick connection coupling to fit the SKF hydraulic pumps and eyebolts, two tommy bars, and four mating holes on their front face.
Figure 1. Hydraulic Nut Parts Diagram
Hydraulic nuts have been proven to significantly reduce work intensity and improve work efficiency when installing or removing rolling bearings with tapered holes. It consists of two main parts: a steel ring (a) with an internal thread and a groove on one side, and an annular piston (b) fitted in the groove. The seals between these two parts are two O-rings (c).
When the high-pressure oil is pumped into the oil chamber (d in Figure 1), the piston is pushed by the high oil pressure to release a huge force, which is enough to install and disassemble the rolling bearing. There is an unthreaded hole (g) on the outer steel ring, which is used to hold the dry gauge (h). The measuring needle of the dial indicator is close to the piston shoulder to measure its axial displacement. NOTE: Push distance can be used to determine proper mounting; refer to skf.com/mount or download

There are also two threaded holes on the steel ring of the hydraulic nut for the adornment of quick connectors for connecting the high-pressure oil pipe of the hydraulic pump; one (f) is on the outside of the steel ring, and the other (e) is on its circular surface. Unused holes must be plugged with the ball plug supplied with the hydraulic nut. The hole used to connect the high-pressure oil pipe needs to be installed with the quick connector 729832A provided with the hydraulic nut. In addition, the standard configuration of the hydraulic nut also includes a spare O-ring, a maintenance kit, and a small iron rod for tightening the hydraulic nut.
