## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3207-0001-0002:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3207-0001-0002:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## 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.
