2, economy, high efficiency, light weight and high precision;
3, can be equipped with manual hydraulic pump, pneumatic hydraulic pump and electric hydraulic pump;
4. Multiple hydraulic nuts can be used at the same time; ;
5. The axial thrust distance required by the bearing can be measured directly, accurately and stably through the measuring ring in the structural design without using a gauge;
6. Hydraulic nuts with the same specifications can be used when installing and disassembling the dismounting sleeve, which are not available in patent hydraulic nuts such as attached tables or hanging connecting blocks;
7. Using the additional screw of the measuring ring to disassemble the nut and replace the damaged O-ring, which saves time and parts cost compared with the general design;
8. The sealed bearing can be installed without measuring the internal clearance of the bearing to determine the axial thrust of the bearing.
