Deep Nitriding Technology Advantages
Based on many years of experience, we confidently recommend deep nitrided screws. A hardness of approximately 900 HV (equivalent to Rockwell hardness 67) and the material's high core strength (850-1,000 N/mm²) provide the following advantages:
- Increased Wear Resistance - Significantly improved surface hardness, extended service life
- Increased Fatigue Strength - Can withstand higher cyclic loads
- Long-term Accuracy Consistency - Maintains stable positioning accuracy
- Extended Actual Service Life - Proven long-term reliability
- Corrosion Resistance - Nitrided layer provides good protection
Screw Ends and Bearing Seats
Deep nitrided screw ends and bearing seats ensure:
- Consistent pitch circle diameter and profile dimension accuracy over the entire length
- High surface quality
- Optimal running characteristics
Lead Accuracy
Lead accuracy corresponds to ISO tolerance grades IT1, IT3, IT5, selected according to application requirements.
