- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3217-2701-2501:1.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.

Compared to the 43mm Width Compact ServoBlock (SKU: 3217-0001-2501), this ServoBlock™ is even more abbreviated in its design, boasting a 27mm width that helps it fit just right in 1143 Series Mini Low-Side U-Channel.

The threaded holes on the face and sides provide for secure attachment via M4 screws. The hub-shaft, meanwhile, maintains the goBILDA® 16mm square pattern of surrounding structure with thru-holes and threaded holes to provide for easy attachment of almost any goBILDA® component.

Importantly, the 14mm diameter protrusion of the integrated pillow block fits through the 14mm diameter holes of Mini Low-Side U-Channel. As a result, when you’re using this ServoBlock® with a goBILDA® 2000 Series Servo, its Hub-Shaft rises 8mm from the face of channel!
