Timing Pulley
Timing Pulley: Timing pulleys in aluminium and steel, precision machined to match your belt profile and bore.
GOODLY manufactures timing pulleys from aluminium alloy and steel on CNC machines, with tooth profiles cut to match MXL, XL, L, H, T5, T10, AT5, AT10, 3M, 5M, 8M, 14M, GT2 and GT3 belts. Pulleys can be supplied with a pilot bore, finished bore, keyway, setscrew, or as rod-shaft and idler types, giving you the exact drive component for your machine rather than a compromise from a catalogue.

What Is a Timing Pulley?
A timing pulley is a toothed wheel machined to match a synchronous belt pitch. The teeth engage the belt to transmit motion without slip, while the bore, keyway and fixing mount the pulley on the shaft. Timing pulleys are made in aluminium for light, high-speed drives and in steel for heavy-duty, long-life drives.
Because we manufacture in our own plant, we can advise on the right compound, cord and tooth profile for your machine before you order, and back it up with sample belts for your own testing.
Key Advantages of Our Timing Pulley
Every belt is engineered, moulded and inspected in house, so the advantages below are backed by real production data rather than marketing language.
Precision CNC Machining
Tooth profile, bore and face are machined on CNC equipment and checked against the belt pitch for true running.
Aluminium or Steel
Light aluminium alloy for high-speed and low inertia, or steel for maximum strength and wear life.
Full Profile Range
MXL, XL, L, H, T5, T10, AT5, AT10, 3M, 5M, 8M, 14M, GT2, GT3 and custom tooth forms.
Custom Bore & Keyway
Pilot bore, finished bore, keyway, setscrew, clamp or taper-lock fixing to suit your shaft.
Rod-Shaft & Idler Types
Integrated rod-shaft pulleys, extended-shaft pulleys and serrated idler pulleys for any layout.
Balanced for High Speed
Accurate concentricity and low imbalance keep timing pulleys running smoothly at high rpm.
Why Buyers Choose GOODLY as Their Timing Pulley Supplier
GOODLY is a belt manufacturer in Guangzhou, China, not a trading company.

Timing Pulley Materials and Reinforcement
We select the compound and the tension member together, because the material combination is what determines how a timing pulley performs over its working life.
Aluminium Alloy
Light and corrosion resistant for high-speed drives and low-inertia automation axes.
Carbon Steel
High strength and wear resistance for heavy-torque and long-life industrial drives.
Stainless Steel
Non-corrosive for food, medical and wash-down equipment.
Surface Treatment
Anodizing, black oxide or zinc plating for extra wear and corrosion protection.

Timing Pulley Frequently Asked Questions
Quick answers to the questions our customers ask most often about timing pulley.
How do I choose between an aluminium and a steel timing pulley?
Aluminium pulleys are light and are ideal for high-speed or low-inertia drives. Steel pulleys are stronger and more wear resistant, so they suit heavy-torque and long-life industrial applications.
Can you machine a pulley to my drawing?
Yes. Send us a drawing or a sample with the profile, tooth number, bore, keyway and fixing details and we will manufacture a timing pulley to match.
What tooth profiles do you supply?
We machine MXL, XL, L, H, XH, T2.5, T5, T10, AT5, AT10, 3M, 5M, 8M, 14M, GT2 and GT3 profiles, plus custom tooth forms.
Do you make rod-shaft and idler pulleys?
Yes. We supply integrated rod-shaft pulleys, extended-shaft pulleys and serrated idler pulleys for linear-motion and tensioning duties.
What is your lead time for timing pulleys?
Standard profiles are usually ready in 7 to 15 working days. Fully custom pulleys depend on the machining and finish required.
