Precision Rotary MotionNexen’s Precision Rotary Motion technology is a combination of very high precision rotary drive systems, high torque rotary brakes, and mechanical torque limiters, all delivering zero backlash. Nexen’s Roller Pinion Gears and Gear Segments (RPG) and fully integrated Precision Ring Drive Systems (CRD and PRD) drive rotary motion with very high precision and zero backlash. Nexen Servo Brakes (SBP) and Indexer Brakes (I*300) provide spring engaged, air released, zero backlash holding and emergency stopping in rotary applications. The zero backlash Mechanical Torque Limiters (MTL) reduce machine downtime caused by torque overloads.
