## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-1910-0025-0816:1` (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-1910-0025-0816:1.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.)

## Description

Though most servos support their splined output shafts with internal bearings, servos’ internal bearings aren’t designed for significant radial loads. This Servo Hub-Shaft comes to the rescue for 25 tooth (H25T) splined servos! It’s designed to be supported by an external 8mm round bore ball bearing.

The output goBILDA® 16mm pattern, offering four of each thru- and threaded holes, allows this Hub-Shaft to drive hub-mounted motion components such as gears, wheels, control arms, and more across the goBILDA® ecosystem of components. The hex counterbores of its thru-holes allow for the secure capture of hex nuts and hex-head screws.

Speaking of goBILDA® compatibility—the hub pattern conveniently remains on-pattern with nearby components when the hub shaft is installed on a goBILDA® 2000 Series Servo. That’s because the Hub-Shaft’s height was chosen specifically with the spline height of 2000 Series Servos in mind!
