PRS Series Planetary Roller Screw
In applications where high loads are anticipated or faster cycling is desired, Exlar’s PRS Series Planetary Roller Screw actuators provide an attractive alternative to the hydraulic or pneumatic options. Electromechanical units using roller screws have major advantages. They do not require a complex support system of valves, pumps, filters and sensors. Thus, Exlar units take up much less space and deliver extremely long working lives with virtually no maintenance.
• Roller screw design provides high speeds, stiffness and shock load resistance compared to other technologies.
• Large static loads – up to 779,000 lbf.
• High screw speeds – 5,000 rpm and above
• Up to 15 times longer life than comparably sized ball screws. Ideally suited for continuous duty applications.
• Preloaded nut options for zero backlash.
When starting any new automation project, In-Position Technologies engineers start by reviewing the key requirements to determine all necessary components needed in an application. This includes providing recommendations for any appropriate controllers, power supplies, sensors, encoders, bearings, couplings, and any other components needed to fit the application. Our engineers perform all necessary engineering assessments to make sure all components perform properly together, are within customer specifications, and do not come with unnecessary costs.
This includes:
• Payload, reach, speed, cycle time, and repeatability requirement
• Specifying the appropriate feedback device (sensors, vision system, torque sensor)
• Verifying mounting compatibility, form factor checks, etc.
• Ensuring compatibility with the current system
• Ensuring all necessary auxiliary equipment are also specified
When ordering PRS Series Planetary Roller Screw actuators as a part of a full system, IP Tech engineers review the solution to ensure:
• All parts and fittings necessary for a complete working solution are included
• All components have been checked and verified to work together as a system
• The selected components will perform as required by the project specifications
