Precision roller system eliminates backlash

Claimed to revolutionise linear drive systems, a precision roller system eliminates backlash and provides accurate positioning while operating at high speeds.

Nexen is proud to introduce an advanced technology that will revolutionise linear drive systems.

Our Precision Roller Pinion System eliminates backlash and provides accurate positioning while operating at high speeds.

The RPS line features a patented tooth design, combined with a pinion consisting of bearing supported rollers to ensure precision and reduce maintenance.

Offering better performance and longer life than traditional rack and pinion or ball screw systems, the Precision Roller Pinion System has models ideal for a variety of linear motion applications.

* Precision operation maintains accurate positioning - the RPS line features an innovative rack and roller pinion combination that provides extremely accurate positioning.

This design eliminates the cumulative error problems experienced with ball screw systems.

The Roller Pinion System also offers backlash-free performance in both directions by maintaining opposing contact with two or more teeth at all times.

This design eliminates the costly and complex split and dual pinion systems required by most traditional rack and pinion systems.

* Patented tooth design ensures quiet operation - the RPS line is designed with bearing supported rollers that move smoothly along the face of each tooth.

This reduces noise levels often associated with other linear motion systems.

* Segmented rack provides easy integration and unlimited travel - Nexen offers the rack in segmented lengths, making it easy to accommodate your application requirements.

Supplied in meter and half-meter increments, length can also be custom cut as required.

The basic system is comprised of just two parts, a rack and roller, making it easy to adapt to any application.

* Rugged design capable of high speeds - the Roller Pinion System maintains accurate positioning at speeds as high as 660 m/min (36 ft/sec).

Even at these speeds, the extremely low friction design does not create heat or wear on components.

Nexen's Roller Pinion System (RPS) converts rotary motion into very precise, backlash-free linear motion.

It does this with a revolutionary design concept that uses a pinion consisting of bearing supported rollers to engage a rack with an innovative tooth profile.

As the pins and rack teeth interface, the rollers move smoothly along the tooth profile, driving the rack.

This design allows zero tooth clearance while providing: * High Precision.

* Repeatability.

* Accuracy.

* No Cumulative Error.

* Zero Backlash.

* 99% Efficient.

* High Speed Operation.

* Virtually No Wear.

* Long Life.

* Low Particle Emissions.

* Low Maintenance.

* Unlimited Length Possible.

* Minimal Noise.

* Easy System Integration.

Roller Pinion System applications include: * Inspection Equipment.

* Gantry Systems.

* Machine Tools.

* Glass Cutting.

* CNC Machining.

* Factory Automation.

* Glass Cutting.

* Robotics.

* Wood Milling.
