Timing Belt Pulley
Timing Belt Pulley: precision aluminium and steel timing pulleys machined for zero-backlash transmission.
A GOODLY timing belt pulley is a toothed wheel machined to match a synchronous belt pitch. Its teeth engage the belt so motion is transmitted positively with no slip, while the bore, keyway or fixing mount the pulley on the shaft. We machine timing belt pulleys in aluminium for light, high-speed drives and in steel or cast iron for heavy, long-life drives, to profiles such as MXL, XL, L, H, T5, T10, AT5, AT10, 3M, 5M and 8M.

What Is a Timing Belt Pulley?
A timing belt pulley is a toothed wheel machined to match a synchronous belt pitch. Its teeth engage the belt so that motion is transmitted positively, with no slip, while the bore, keyway or fixing mount the pulley on the shaft. Timing belt pulleys are made in aluminium for light, high-speed drives and in steel or cast iron for heavy, long-life drives, and are matched to profiles such as MXL, XL, L, H, T5, T10, AT5, AT10, 3M, 5M and 8M.
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 Belt 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 Hobbed Teeth
Teeth are cut to match the belt pitch for accurate, quiet and slip-free engagement.
Aluminium & Steel
Light anodised aluminium for speed, steel or cast iron for heavy, long-life drives.
Custom Bore & Fixing
Bores, keyways, tapped holes, grub screws and clamp fixings machined to your shaft.
Dynamic Balance
Pulleys can be balanced for high-speed running with minimal vibration.
Full Profile Range
MXL, XL, L, H, T5, T10, AT5, AT10, 3M, 5M, 8M, 14M and special profiles.
Own Machining Shop
Turned, hobbed and finished in our factory for consistent quality and lead time.
Why Buyers Choose GOODLY as Their Timing Belt Pulley Supplier
GOODLY is a belt manufacturer in Guangzhou, China, not a trading company. We control the compound, the cord, the moulding and the final inspection, which is why our timing belt pulley keeps the same performance from the first sample to the last production batch. Send us a drawing or a used belt and we will match it, improve it if we can, and supply it on a schedule you can plan around.

Timing Belt Pulley Performance Data
The figures below are typical values from our own testing. Your exact application may need a different combination, so tell us the load, speed and environment and we will confirm.
| Tooth profile accuracy | ±0.01 mm on standard profiles |
| Concentricity | High, for smooth high-speed running |
| Material | Aluminium 6061 / 7075, steel C45, stainless, cast iron |
| Balancing | Available for high-speed drives |
| Surface finish | Anodised, black oxide or plated |
| Service life | Long, with hard-wearing tooth flanks |
Timing Belt Pulley Materials and Reinforcement
We select the compound and the tension member together, because the material combination is what determines how a timing belt pulley performs over its working life.
Aluminium Alloy
Light and corrosion-resistant, ideal for high-speed and low-inertia drives.
Steel & Stainless
For heavy torque, higher temperatures and long-life industrial drives.
Cast Iron
Dense and stable for large, heavy-duty pulleys on rugged machinery.
Surface Treatment
Anodising, black oxide or zinc plating for wear and corrosion resistance.
Industries That Use Our Timing Belt Pulley
From food and packaging to printing and automated assembly, the same engineering discipline is applied to every timing belt pulley we ship.
Custom Timing Belt Pulley Options
Almost every order we make is a variation. Tell us the machine and the product, and we will tailor the timing belt pulley to fit.
Custom Bore & Keyway
Bores, keyways, tapped holes and grub screws machined to your shaft.
Special Profiles
Non-standard and custom tooth profiles machined to a drawing or sample.
Surface Finish
Anodised, black oxide, zinc plated or natural finishes.
Balancing & Flanges
Dynamic balancing and single, double or no flanges to suit the drive.
Our 8-Step Quality Control for Timing Belt Pulley
Each timing belt pulley passes the following checkpoints before it is packed, and the records are kept against your order number.
Timing Belt Pulley Frequently Asked Questions
Quick answers to the questions our customers ask most often about timing belt pulley.
How do I specify a timing belt pulley?
Tell us the belt profile (for example T10, AT10, 5M or XL), the number of teeth or the pitch diameter, the bore and fixing, and the material. We will machine it to match your belt and shaft.
Should I choose an aluminium or steel pulley?
Choose aluminium for light, high-speed and low-inertia drives where weight and corrosion matter. Choose steel or cast iron for heavy torque, higher temperatures and long-life industrial drives.
Can you machine a custom bore or keyway?
Yes. We machine plain, keyed, tapped, clamped and shafted bores to your drawing, including grub screw and keyway details.
Do you make special or non-standard profiles?
Yes. Alongside the standard range we machine special tooth profiles to a drawing or a sample, including matching a pulley to a belt you already use.
How long does production take?
Standard timing belt pulleys are typically ready in 7 to 10 working days, with a little longer for special profiles or surface treatments.
