SBS Ball Screws - Product Specification
Nut Types and Wiper Systems
Double Nut with 2-Point O-Preload
- Preload Adjustment - Preload adjustment by aligning the flange nut and lock nut using a ground wedge key
- Stable Low No-Load Torque - Low torque maintained at high rigidity
- High Precision Positioning - Precise positioning even at low speeds and oscillating short stroke movements
- 2-Point Ball Contact - Better efficiency compared to 4-point ball contact
- Optimal Technical Solution - Minimal heat generation and minimal wear
Single Nut with 4-Point X-Preload
- Ball Sorting Preload - Single nut preloaded by ball sorting with 4-point ball contact between nut and screw
- Compact Design - Requires shorter screw length than double nut for the same stroke
- Production Tolerance Considerations - Due to production tolerances, single nuts are mainly used for shorter ball screws
- Load Peak Protection - No inadmissible complete ball disengagement even during load peaks
- Economical Manufacturing - Single nut ball screws can be manufactured more economically than double nuts
Wiper Systems
