Hydraulic nuts are primarily used for keyless connections of components. Their working principle involves using ultra-high pressure oil to generate a thrust on the shaft and a tension on the sleeve, ensuring a uniform force distribution to connect the shaft and sleeve together.
　　*Available in both axial and radial oil injection methods;
　　*Pressure is evenly distributed across the pressure ring;
　　*Standard working pressure is 63 MPa or 153 MPa;
　　Application range:
　　*Installation and removal of bearings; can be customized according to customer requirements for use in the metallurgical copper and aluminum metal industry, hydraulic locking nuts on slitting machines.
　　*Installation and removal of propellers, rudder bearings, etc.;
　　*Disassembly of high-pressure joint surfaces, such as train wheels, couplings, flywheels, and gears;
　　Suitable for installing and removing tapered bore bearings with an inner diameter of 50 mm or more. This method is simpler and more time-saving than mechanical methods. SL-HMV..E hydraulic nuts are available with metric or imperial thread designs, and there are also nuts without threaded holes for some special applications.
　　When used in conjunction with a hydraulic pump equipped with an electronic pressure gauge and a depth micrometer, the simplicity and precision of the SKF bearing hydraulic push method (SKF Drive-up Method) can be fully utilized.
　　Installing and removing bearings on tapered shafts or sleeves is often a difficult and time-consuming task. Using SOLY brand hydraulic nuts can reduce such issues. The force generated by pumping oil into the nut to drive the piston is sufficient for installing and removing bearings—effortlessly, accurately, and safely. All hydraulic nuts come with a quick-connect coupler to attach to the hydraulic pump.
　　
　　Up to HMV 200E (d=1.000 mm):
　　●Suitable for shaft diameters from 50 mm to 1000 mm;
　　●Special threads can be provided upon request;
　　●Reduces bearing installation time;
　　●Precise and safe bearing adjustment
