The VTMF Series Rotary Index Table Servo Trunnion was engineered to satisfy the needs of the 21st century industrial manufacturing environment: fast, strong, reliable, high quality and cost effective. The VTMF Series programmable rotary indexing trunnion features a cast housing that is compact and has all the characteristics a manufacturer looks for: large center thru-hole for running utilities and mounting equipment, a compact housing to save on floor space and improve design flexibility, a completely sealed housing for mounting the unit on its side, and a large rotating diameter for increased mounting surface.

The VTMF Series Rotary Index Table Servo Trunnion was designed to be a completely programmable solution. This allows for a minimum of 4 oversized cam followers to be engaged with the barrel cam at all times. This programmable rotary indexing trunnion is driven directly by a gear reducer coupled to either an AC motor with encoder or servo motor. Both options provide very high accuracy (less than 10 arc seconds) and allow for the indexer to be driven by a dedicated amplifier or as an auxiliary axis to a robot drive. Loading capabilities are multiplied significantly in this line of indexers through the design of the barrel cam and cam followers. This unique design allows for unprecedented inertial load as a function of index time capacity.
