12-3M-9 HTD PULLEY

Product Details

The 12‑3M‑9 pilot bore timing pulley is a compact, precision‑machined pulley designed for synchronous belt drives using the 3M tooth profile. With 12 teeth and a 9 mm face width, it provides smooth, accurate and low‑noise power transmission in light‑duty machinery, automation systems and small mechanical assemblies. The 3 mm pitch tooth form ensures reliable engagement with matching 3M timing belts, supporting stable indexing and slip‑free operation.

Pilot bore pulleys offer flexibility for machining to suit specific shaft sizes or keyway requirements, making them ideal for OEM builds, machine upgrades and maintenance applications. The lightweight 3M profile is commonly used in compact equipment such as pick‑and‑place units, desktop automation, laboratory devices, small conveyors and precision motion systems where space efficiency and accuracy are essential.

Manufactured from high‑quality materials for durability and dimensional accuracy, the 12‑3M‑9 pulley delivers consistent performance under continuous operation. It forms part of Transpower’s extensive range of 3M pilot bore pulleys, covering multiple tooth counts and widths to suit a wide variety of synchronous drive layouts.

From our base in Wellingborough, Northamptonshire, Transpower Drives supplies 3M pulleys to engineering firms across Northampton, Kettering, Corby, Milton Keynes, Bedford and the wider East Midlands, with fast national delivery to OEMs, workshops and maintenance teams throughout the UK.
