Nexen MRS Motor-Ready Sealed Rotary Indexers

Nexen MRS Motor-Ready Sealed Rotary Indexers
Nexen MRS combines a sealed rotary indexer, precision bearing and roller-pinion ring transmission with a motor/gearhead-ready input. The current catalog separates a no-gearhead arrangement from MRS assemblies carrying a planetary gearhead. This distinction matters: zero backlash of the roller-pinion mesh does not establish zero backlash through every added motor/gearbox combination.
Review Summary
Consider MRS for compact servo-driven indexing with a large central opening and a documented load/inertia. Select the exact input arrangement, size and operating duty. The published 304 rpm maximum belongs to selected configurations and differs from maximum continuous velocity.
