- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3217-0001-2501:1.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.

## Description

This 25 tooth ServoBlock® isolates radial loads from your servo with a robust frame that’s highly compact, super mountable, and rocking an integrated bearing to support its hub-shaft.

Threaded holes on its face and sides allow for a staggering array of mounting options. Meanwhile, its hub-shaft maintains the goBILDA® 16mm pattern of surrounding structure with thru-holes and threaded holes to provide for easy attachment of almost any goBILDA® component.

And thanks to the 43mm width of this ServoBlock®, you can do more than simply install it inside U-Channel. You can even incorporate 1120 Series U-Channel or 1121 Series Low-Side U-Channel into its structure to build an incredibly robust servo assembly!

It helps that the 14mm diameter protrusion of the integrated pillow block fits into the 14mm diameter holes of U-Channel. Consequently, when you’re using this ServoBlock® with a goBILDA® 2000 Series Servo, its hub-shaft rises 8mm from the face of channel!
