Motion Index Drives’ 7th Axis Slide Robot Transfer Unit (RTU) offers high-precision guard rails, closed-loop motor control systems, and rack and pinion systems. These features allow you to manufacture the best products possible with maximum efficiency.

At Motion Index Drives, we manufacture our RTUs to suit the various servo motor brands our customers use for their automation applications. Our RTUs are suitable for material handling jobs or any type of welding or dispensing application.

Key Benefits

Here are some of the key benefits of 7th Axis Slide Robot Transfer Units:

  • Manufactured to accept any robot brand motor
  • A complete application study on load capacity and speed
  • High-precision linear rails/guideways with blocks
  • Cable management and cable management tray (to be mounted internally or externally by Motion Index Drives)
  • Hard stops on each end of transfer for over-travel
  • Leveling bolts, weld brackets and leveling plates
  • Special coating to reduce friction and eliminate external lubing
  • Installation support at the customer’s facility


The 7th Axis Slide Robot Transfer Unit supports many industrial applications. Users can choose how it is installed — floor-mounted, elevated or inverted configurations. Some of the capabilities of the 7th Axis Robot are:

  • 1.5 meters per second of transfer time
  • Standard accuracy — DIN 6 on gear rack +/-0.0003”/ft
  • Heavy-duty linear bearings for high-tilting movements
  • Gear reducer for low backlash
  • Armoloy coating on gear rack for lube-free operation (optional)


Our 7th Axis Robot offers many advantages to users, but especially so for design engineers and special machine builders. These are just some of the benefits you can enjoy from this highly efficient robot transfer unit:

  • Higher accuracy and better performance: The 7th Axis Slide utilizes a direct drive gear reducer and gear rack that enhances accuracy and performance with fewer components.
  • Easy maintenance and accessibility: The robust steel construction allows easy maintenance and accessibility of the robot.
  • High mass capability: The oversized linear bearings guideways enable the robot to handle more mass.
  • High linear speed: The oversized rack and pinion system allows high linear speed in virtually unlimited travel lengths. The system also increases safety during operations.
  • Locally made: Reliable technical support on product inquiry and ongoing maintenance within the USA.
  • Space-saving: The 7th Axis transfer unit increases production, thereby reducing the need for additional floor space to accommodate more machinery.
