The Motion Index Drives RTF flexible trunnion rotary index drives series encompass our small to medium range of sizes, ranging from our model RTF450 up to our RTF900. Our programmable cam indexing trunnions are offered in three levels of accuracy, ranging from 30 arc seconds down to 5 arc seconds. The RTF programmable cam indexing trunnions can are operated with; AC motors with encoders, servo motors or robot auxiliary axis motors. The number of positions or stops are infinite with our fully programmable cam indexing trunnions. There are always multiple cam followers that are engaged in the cam at all times, which provides a very strong rotary indexer for their relative size. Zero backlash operation is realized in the fully programmable RTF trunnion indexers by using cam and cam follower technology. There is zero backlash on the output flange during operation and while in-position.
