Technical Overview
The Module 1.0 Internal Gear Rack is a linear motion transmission component designed to seat directly inside the channel of V-Slot linear rails and standard 20mm profile T-Slot extrusions. This component functions as a direct alternative to traditional lead screw and nut block setups or belt and pulley systems, translating rotational motion from a matching pinion gear into accurate linear movement. The gear rack is secured firmly within the aluminum extrusion channel by using a standard T-nut and bolt assembly at each end of the run.
To facilitate continuous linear travel across extended spans, the ends of each rack segment feature a specialized interlocking profile optimized for butt-joining. This configuration allows multiple individual lengths to form continuous, uninterrupted runs, successfully removing the structural travel limits typically imposed by standard commercial lead screw lengths. The rack features a slightly compressible design, allowing users to tightly abut adjacent sections for seamless transitions.
Applications
This internal gear rack is primarily utilized in automated positioning networks, custom CNC machinery, and large-format linear motion assemblies where long-travel distances must be achieved without losing mechanical efficiency. Because the rack profile mounts entirely within the existing recess of the structural aluminum rail, it provides a highly compact, self-contained transmission loop that minimizes the overall machine footprint.
The component is well-suited for heavy-duty linear actuators, industrial automation setups, and specialized gantry systems. It allows engineers to build modular, scalable motion axes of virtually any length by cascading multiple units end-to-end.

Maker Store Tips and Tricks
-
Mount the internal gear rack facing downward within the extrusion channel whenever possible to prevent dust, chips, and processing debris from settling between the gear teeth.
-
When butt-joining multiple segments together for long runs, apply a single small drop of adhesive to both interfacing ends and secure the joint location firmly using sliding T-nuts on both sides of the extrusion split to ensure a tight, perfectly aligned interface.
-
Take advantage of sliding T-nuts on the extreme ends of your extrusion assembly to compress the rack elements together slightly, eliminating any residual gaps at the joints.
Please note:
- The gear rack is approximately 499mm in length and is designed to be compressible. You can add a Sliding T-Nut on both ends of the extrusion to ensure a tight fit. For butt joining the racks, you may apply a small drop of glue on both ends of the rack and then add a Sliding T-Nut on both ends of the extrusion.
