Overview
The Barry 2-015 ROH’LIX linear actuator is a proven mechanical actuator designed to convert rotary shaft motion into linear thrust and movement. The ROH’LIX device converts rotary motion into linear motion using rolling element ball bearings that trace a helix pattern along the shaft, which produces a Rolling Helix. This unit operates in both horizontal and vertical configurations, making it suitable for a wide range of industrial automation, machinery control, and positioning tasks. The unit is in used condition and has been tested for full operational capability.
Key Features
- Threadless, mechanical, screw-type design that converts rotary motion into precise linear motion and thrust using rolling-element ball bearings
- Coil springs maintain a constant tension against adjustment screws, so thrust settings do not change once set
- Bearings are lubricated for life and reduce backlash to less than 0.001 inches for increased accuracy
- Overload protection feature allows the block to slip on the shaft when obstructions are encountered, reducing downtime and preventing damage
- Maintenance-free operation in most applications aside from occasional minor cleaning
- Provides a minimum of 90% mechanical efficiency

Typical Applications
The Barry 2-015 ROH’LIX can be used in horizontal or vertical axial loading applications. Common uses include manufacturing machinery positioning, production line actuators, assembly equipment linear drive, machine tool control systems, and precision positioning in factory automation. Axial loading allows for even load distribution across all six of the device’s bearings. This unit is well-suited for facilities requiring low-maintenance, reliable linear motion conversion in compact spaces.
