Rotary Indexing Tables Overview

Rotary Index Tables

Rotary Indexing Tables convert a uniform input motion into an intermittent output motion through the use of a precision-machined barrel cam. Motion Index Drives cam hardening process for our rotary index tables utilize custom cam followers to increase system accuracy and component lifespan when compared to processes used by leading competitors. Motion Index Drives rotary indexing tables have a variety of station and speed settings, including programmable Motion Flex units (servo motor and encoder tables) and fixed mechanical systems. In addition, Motion Index Drives can manufacture MEDEX units for medical instrument production providing clean room rotary indexers, or with Motion’s patented NANO Indexer Technology, making Motion’s rotary tables the most accurate barrel cam tables in the world.
