Scope of Application:
- Axial locking of blades in metal slitting machines and cutting machines;
- The disc shear uses a tool clamp for locking.
- Tool chuck locking;
- Tools and fixtures for fastening the forming and machining shaft;
- Fastening fixtures for forming processes;
- Other shaft-mounted tools and fastening fixtures;
Advantages of Hydraulic Locking Nuts:
- The body is made of aluminum-titanium alloy, completely replacing imported products. It features a knurled surface, is lightweight, and is easy to install and disassemble using a specific wrench.
- It has a large axial locking force, which firmly locks the blades on the slitting machine and prevents deformation under axial pressure;
- It reduces blade wear, extends blade life, shortens tool setting time, improves equipment efficiency, and produces slits with very small burrs.
- No lubrication required, stable axial force, good sealing, and no oil leakage;
- Sealed grease type, no need for external pressure relief;
- Achieve the best results with a small amount of oil; clean and environmentally friendly.
- Custom-made threaded and unthreaded hydraulic nuts according to customer requirements;
