more information Precision Roller Pinion Systems

The Roller Pinion System (RPS) is based on an innovative pinion consisting of bearing-supported rollers and a unique tooth profile. This unique drive system provides very high positional accuracy, near-zero backlash, virtually no cumulative error, low-velocity ripple, unlimited length, very high speeds, high rigidity, low noise, low (in some cases no) maintenance, corrosion resistance, long life, and 99% efficiency. This opens up new machine design possibilities and provides the capability to achieve much higher levels of performance.

more information Rail Brakes

Nexen’s RB Series of linear profile guide rail brakes uses spring force to secure the load in holding applications. Superior response time, high force for stopping, and holding in e-stop and power-off situations. Each RB brake clamps directly onto the center of the guide rail to provide positive braking and holding in all axes, with no effect on bearing surfaces. These profile rail brakes hold position accurately by reducing drive train backlash and elasticity.

more information Rod Locks

Nexen’s Static Rod Locks deliver precision holding with virtually no backlash, providing high accuracy in demanding applications. These spring-engaged, air-released units come in both ISO and NFPA sizes. The Rod Lock’s large clamping surface ensures high clamping/holding force and Nexen offers models for use on a pneumatic cylinder or as a stand-alone unit on a guide rod. The design is sealed and features a natural brushed aluminum finish or a corrosion-resistant, anodized finish.

more information Servo Motor Brakes

Spring engaged, air released servo motor brakes mount to the shaft end of servo motors up to 20 horsepower. The brake acts as an adapter between dissimilar mounting features. The brake bore accepts the motor shaft that is fixed inside the brake with a split hub/shaft collar. This brake is a high-torque, zero backlash device.
