## Description

This Servo-Driven Gear Rack Kit creates linear motion using a servo. With an impressive thrust spec that’s almost unbelievable compared to its overall compactness, this kit is a fantastic way to implement back-and-forth motion in your project.

This kit is driven by a 5-Turn Dual Mode Torque Servo that gives the kit its nominal 27kg thrust, 60 mm/sec speed specs. Five other options are available across the [Single and Dual Gear Rack families.](https://core-electronics.com.au/gobilda/kits/linear-motion-kits/gobilda-kits-linear-motion-kits-servo-driven-gear-rack-kits.html) Both families offer three choices of servos that each provide different thrust and speed specs.

The two gear racks are fastened to Square Beams that provide for a huge variety of attachment options via threaded holes on the goBILDA® 16mm linear pattern. The included U-Channel structure, meanwhile, provides a multitude of mounting possibilities. Aside from utilizing the build-system-wide attachment possibilities of the goBILDA® 16mm square pattern thru holes and 14mm center holes in the kit’s included U-Channel, you can also swap out either or both of the included channel with a same-Series channel length of your choice.
