Core Performance and Features:
- Pure Tensile Strength, No Torsion: Avoids bolt torsional stress, increasing fatigue life by 30%+, and providing 20-30% more clamping force for bolts of the same specification;
- Strong Vibration Resistance and Loosening Prevention: Wedge/ring locking structure, preload attenuation under vibration conditions <5%/100h;
- Adaptable to Confined Spaces: No wrench required for turning space, suitable for compact parts of coal mining machines and tunneling machines;
- Corrosion and Temperature Resistance: Dacromet coating shows no red rust after 1000h salt spray, sealing withstands -40℃ to 120℃;
- Reusable Assembly and Disassembly: Key dimensional changes <0.02mm after 100 cycles;
- Multi-Bolt Synchronous Tightening: Multiple interfaces connected in parallel, uniform force distribution, avoiding flange uneven loading and leakage.
Main application scenarios:
- Coal mining machines: rocker arms, cutting drums, traction flanges;
- Tunneling machines: cutterheads, body connections, reducers;
- Hydraulic supports: top beams, bases, column heads;
- Scraper conveyors: head frames, tail frames, sprocket assemblies;
- Flange and shaft fastening for heavy-duty equipment such as mine hoists, ventilators, and air compressors.
