Precision-ground stop nut system with dual locking mechanism, featuring wear-compensating threads and anti-backlash design. The staggered dual-nut configuration eliminates axial play while maintaining smooth adjustability. Hardness graded at 58-62HRC for thread surfaces ensures 50,000+ cycle durability under ISO 3408-3 testing standards.
- Linear guide end-stop calibration in CNC machining centers
- Z-axis height limitation in 3D printing/Pick-and-place machines
- Modular fixture positioning for automotive welding jigs
- Safety overtravel prevention in hydraulic cylinder rods
- Repeatable stage positioning for semiconductor handlers
Mounting protocol:
Apply Molykote G-5002 lubricant to threads before installation.
Tighten main nut to 50N·m using torque wrench, then secure locknut
at 30N·m while holding main nut stationary. Re-torque after 24hrs runtime.
