The Kerk® SRA Series General Purpose ScrewRail® Linear Actuator uses a standard nut for general applications where anti-backlash compensation is not required. The SRA is recommended anywhere low drag and minimal free play is required. A ScrewRail® combines both guidance and load support functions in a single, coaxial component, saving as much as 80% of the space used by a two-rail system.
- Low drag, free play nut without anti-backlash compensation
- Available in four sizes
- Stroke Lengths up to 1.5 meter
- Kerkote® TFE coating and self-lubricating nut ensure long life without maintenance.
