Roh'Lix - The innovative solution
Small, compact - good!
What characterizes a Zero-Max Roh’Lix compared to classic ball screws, or what characterizes the Rohl`Lix linear actuator in general? In principle, the operation of the Roh’Lix is based on the frictional contact between the bearings used and the shaft. The rolling path along the shaft follows a helix, therefore the name Roh`lix for “Rolling Helix”.
The design is based on a split housing block, which offers easy radial mounting and dismounting. The actuator’s solution concept allows adjustable overload protection by adjusting screws. If the maximum allowed force is exceeded, the linear actuator slips and protects other components from damage.
What specifically are the advantages compared to ballscrews?
• Integrated overload protection (no additional torque limiters required)
• High lifetime expectancy
• Highspeed operation up to 1750 mm / second possible
• No additional lubrication necessary

In which applications do Zero-Max Roh'Lix offer a real alternative?
In particular, applications that require smooth operation can benefit from Roh`Lix linear actuators. Roh`Lix do not exhibit a “stick / slip” effect that often occurs in ball screws. A “stick / slip” effect is the phenomenon when the static friction is much higher than the sliding friction.
Further, pneumatic and hydraulic applications can benefit where fluctuating pressure conditions are expected. The Zero-Max actuator has proven to be particularly effective for applications requiring high linear travel speeds. The ability to adjust the slope allows for the highest travel speeds.
