Features:
- The HMV series bearing hydraulic nuts are mainly used for keyless connections of connectors. Their working principle utilizes ultra-high pressure oil to generate a thrust on the shaft and a tension on the bushing, ensuring the shaft and bushing are evenly connected. The installation process is safe, accurate, and efficient.
- Installation is simple, quick, accurate, and efficient;
- There are two methods of oil injection: axial and radial.
- Pressure is evenly distributed on the pressure ring;
- Standard operating pressure: 0-1500 bar;
Scope of use:
- Bearing installation and removal; custom-made to customer requirements; suitable for papermaking machinery, cement machinery, and metallurgical copper and aluminum industries.
- The HMV type hydraulic nut is suitable for installing and removing tapered bore bearings with an inner diameter of 50mm or larger. This method is simpler and more time-saving than mechanical methods. The hydraulic nut is available in metric or imperial thread designs, and a threadless nut is also available for some special cases.
- Installing and removing bearings on tapered shafts or sleeves is typically a difficult and time-consuming process. Using hydraulic nuts can reduce these problems. The oil pumped into the nut provides sufficient force to drive the piston, allowing for effortless, accurate, and safe bearing installation and removal. All hydraulic nuts come with a quick-connect coupling for connecting to a hydraulic pump;
- Metric hydraulic nuts range from HMV50 (d=50 mm) to HMV1000 (d=1,000 mm);
- Suitable for shaft diameters from 50 mm to 1000 mm;
- Special threads can be provided upon request;
