Product Media
- Ball screws are made from alloy steel and case hardened to Rc56 (minimum).
- A black oxide finish is applied to prevent corrosion during shipping and for a brief storage period.
- The rust inhibiting properties of the screw lubricant offers additional corrosion resistance.
- Ball nut housings are steel with case hardened threads. A black oxide coating provides additional protection.
- Flanges are constructed of steel with a black oxide coating.
