General Overview

The Motion Index Drives RT Series of Rotary Index Drives encompasses a large range of sizes, ranging from our model RT100 up to our RT1250. In addition, special cam-driven devices can be custom made to order for your automation needs. RT Series Rotary Index Drives are offered in a fixed number of stations or as a flexible turntable with a servo motor or standard AC brake motor with encoder. With the addition of Motion’s patented NANO Indexer Technology, the RT Series becomes the world’s most accurate barrel cam indexers.

RT Series index drives are constructed with strength and reliability in mind. Robust design and components ensure this device will maintain precision in intense factory settings.
