- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3417-4008-0016:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals.

## Description

Engineered specifically for 5mm HTD belts with widths of 9mm or less, this 24 tooth, 8mm REX™ bore pinion pulley features a profile-matched bore to create a positive drive, while a pair of set-screws prevent the pulley from moving axially on a shaft. Built-in shims on each side allow the pulley to rest against a bearing while providing clearance between the pulley and the bearing’s outer race.
