Roller pinion system and precision ring drive
IMTS 2012: Nexen's Roller Pinion System (RPS) and precision ring drive (PRD), which are designed for motion control challenges and rotary positioning applications, respectively.
Nexen's Roller Pinion System is specifically engineered to meet diverse and demanding motion control challenges. It features a unique roller pinion/toothed rack combination that delivers high-accuracy positioning with zero backlash and virtually eliminates cumulative error. Constantly evolving in order to provide the widest range of high-quality motion control solutions, the RPS is offered in five distinct models, each 99 percent efficient, with low friction and minimal maintenance requirements.
For indexing and rotary positioning applications, Nexen’s PRD contains a roller pinion system that is 99 percent efficient and a gearbox that performs at a 96 percent efficiency rating for smooth, precise motion. Reaching speeds of 300 rpm and lasting up to 60,000,000 revolutions, the PRD combines power, rigidity and durability while maintaining high performance capacity at lower energy costs.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
