Overview
The linear tracks is also called the robot seventh axis, travel rail, external axis, etc. It is a common form of a robot transfer unit (RTU) and mainly consists of a base, robot carriage, reducer/servo motor, gears, linear guide rails, drag chain, etc. It is usually bolted to the floor and, through interfaces and custom programming, enables the robot to move accurately to different positions during operation, greatly expanding the robot's working range.
Our robot ground rails are classified by sealing type into open, semi-enclosed, and fully enclosed types, and by rolling method into linear guide type and roller type. The main body material is generally steel, stainless steel, or aluminum alloy. Robot ground rails are widely used in painting, welding, handling, palletizing, casting, dispensing, machine tool loading, intelligent warehousing, automotive manufacturing, and other fields.
The ground rails produced by our factory integrate and work in linkage with industrial robots from ABB, KUKA, FANUC, Yaskawa, and other manufacturers, and can be custom-built to non-standard specifications according to customer project requirements, including travel, load, speed, and other parameters as well as structural materials and additional accessories. They feature high precision and a low failure rate.

Core Advantages
Adds a seventh linear axis to the robot for continuous operation across multiple stations, reducing robot count and line footprint.
Reinforced steel plate, fully welded construction for ample rigidity—stable at high speed under heavy loads, with no deformation over long strokes.
Servo motor + precision reducer + full closed-loop control for repeat positioning accuracy of ±0.05 mm (precision models ±0.03 mm).
Standard sections splice together for strokes from 1 m to hundreds of meters, and a single Linear Track can carry multiple robots at once.
Limit switches + mechanical anti-collision locks + optional safety light curtains / E-stops; conductor rail power supply eliminates cable carrier wear for easy maintenance.
Supports EtherCAT / PROFINET for synchronized interpolation with ABB / KUKA / FANUC / Yaskawa six-axis robots.
