High-pressure jack device for plain bearing

The utility model relates to a high-pressure oil jacking device for a sliding bearing. A high-pressure oil jacking hole is installed at the bottom of a shaft bushing; two symmetrical linear grooves are installed at both sides of the high-pressure oil jacking hole, which can not only efficiently locate the high-pressure oil jacking device but also avoid the interference of the high-pressure oil inlet tube and the oil ring; a section of deep groove is respectively installed at one end of the linear groove near the high-pressure oil jacking hole for installing the pipe joint of a high-pressure oil pipe to facilitate better location; the two linear grooves use a bilateral symmetry structure, so that the high-pressure oil jacking device can be installed at any side of the bearing and convenience is provided for field installation. The high-pressure oil jacking device efficiently uses the space of the bearing, has the characteristics of compact structure, saved space, convenient installation and simple technology,
