MOTION CONTROL: Nexen’s Roller Pinion System (RPS) provides linear positioning with zero backlash and simple installation in precision motion control applications. The RPS features an ISO 9409 flange ...

High speeds and accelerations, uneven loads, or vertical orientations in crossed-roller rail-guide applications can cause "cage creep," or cage and roller assembly migration. In most cases, as the ...

Mechanically preloaded split-pinion drives have an axial spring to load one pinion half against the other. And electrically preloaded dual-pinion drives have two motors, each driving one pinion, which ...

(A1) Asymmetric driving principle PMP and its normal force analysis. (A2) Force and motion analysis of the PMP. (B1) Schematic diagram of the rack-and-pinion mechanism. (B2) Schematic diagram of the ...
