Motor-driven rotary table RAS series

horizontalfor machine toolsflexible

Description
The single-sided rotary and swivel tables in the RAS series are directly driven, maintenance-free precision axes designed for compact, dynamic machine integration. Water-cooled torque motors provide very high accelerations and torques while backlash-free direct drive ensures repeatable positioning. High-resolution encoders deliver accuracies down to 1.5 arc seconds. Models support load capacities up to 300 kg and selectable maximum speeds depending on the variant.
