Servo-Driven Systems Replace Belt-Driven Track Designs
Track manufacturers have introduced servo-driven rack-and-pinion systems that deliver positioning repeatability an order of magnitude tighter than traditional belt-driven designs, a precision improvement that opens track mounting to applications previously restricted to fixed robot installations. FANUC and ABB both expanded servo-driven product lines in 2025, extending positioning accuracy from several millimeters down to under one-tenth of a millimeter for the most demanding assembly applications. This tightening precision is displacing legacy belt-driven equipment that cannot meet the new tolerance specifications regardless of travel speed. Several additional vendors are expected to match this tolerance tier within the next two years.
