X42 Indexing Actuator

X42 indexing actuator
X42 Dual Rack Indexing Actuator


This unique device indexes with very high accuracy and no accumulating error. Floating pistons and a precision ground rack riding in replaceable sintered bronze bearings assure millions of reliable duty cycles. It is ideal for use in medium to large index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations. With over 10 times the maximum torque capacity of the X1 Indexing Actuator, the X42 is a safe choice for OEM's and integrators.
