Description

H-Type Timing Belt Pulley — 12.7mm Pitch Synchronous Wheel for Reliable Power Transmission

When your DIY automation project demands slip-free, synchronised motion, a mismatched or worn pulley becomes the weakest link in the drive train. Makers, workshop engineers, and small-batch machine builders who need a dependable H-profile synchronous wheel will find this timing belt pulley engineered to keep every axis in step.

This H-type timing belt pulley features a 12.7mm (1/2 in) pitch profile and a 27mm (1.06 in) belt-contact width. Tooth counts range from H10T to H30T, and bore diameters span 8–30mm (0.31–1.18 in), covering the most common shaft sizes used in light-to-medium industrial and hobbyist drives. The body is machined from aluminium alloy with a natural or anodised finish, keeping rotating mass low while maintaining dimensional accuracy.

Typical use cases include CNC router X/Y axis drives requiring precise H-belt synchronous wheel positioning, conveyor belt timing pulley replacements in small packaging lines, and 3D printer or laser cutter motion systems where a 12.7mm pitch aluminium timing pulley delivers the tooth engagement needed for consistent layer accuracy.

⚙️ Compatibility: Designed for standard H-profile (1/2 in pitch) timing belts with 27mm width. Verify your belt pitch, width, and shaft bore before ordering.

✅ Key Features of These H-Type Timing Belt Pulleys

  • 🔩H-Profile 12.7mm Pitch — Matches standard 1/2 in pitch H-series timing belts for zero-slip synchronous power transmission.
  • 📐Wide Tooth Range: H10T–H30T — Select the exact tooth count to achieve your target speed ratio without custom machining.
  • 🕳️Bore Options 8–30mm — Covers the most common shaft diameters used in servo motors, stepper motors, and gearbox outputs.
  • 🏗️27mm Belt-Contact Width — Wider engagement surface distributes load evenly, reducing belt edge wear in continuous-duty applications.
  • ⚖️Lightweight Aluminium Alloy Body — Low rotational inertia supports faster acceleration and deceleration cycles in motion-control systems.
  • 🔧Machined Bore for Shaft Fit — Precision-bored hub accepts standard keyway or set-screw retention; bore size confirmed per selected variant.

❓ Frequently Asked Questions

How do I choose the right number of teeth for my drive system?

The tooth count determines your speed ratio. Divide the driver pulley teeth by the driven pulley teeth to get the ratio. For example, an H20T driver paired with an H10T driven pulley gives a 2:1 speed increase. Select tooth counts that achieve your target RPM or torque ratio without exceeding the belt's rated tension.

Which bore size should I order for my motor shaft?

Measure your motor or gearbox output shaft diameter with a calliper. Choose the bore option that matches exactly — available sizes are 8, 10, 12, 14, 15, 16, 17, 18, 19, 20, 22, 24, 25, 28, and 30mm. If your shaft uses a keyway, confirm the variant includes a keyway slot or plan to use a set-screw retention method.

Is this pulley compatible with standard H-profile timing belts?

Yes. This pulley is machined to the H-profile standard with a 12.7mm (1/2 in) pitch. It is compatible with any H-series timing belt of 27mm width. Confirm your belt's pitch and width before ordering — MXL, XL, L, and XH belts use different pitches and are not interchangeable.

How strong is this pulley under continuous load?

The aluminium alloy construction provides a good strength-to-weight ratio suitable for light-to-medium duty continuous operation. For heavy shock loads or high-torque industrial drives, verify the pulley's rated load against your application requirements. The 27mm belt width distributes tension across a wider contact area compared to narrower H-profile pulleys.

Will this pulley corrode in humid or outdoor environments?

Aluminium alloy has inherent oxidation resistance that forms a protective layer on the surface. For prolonged outdoor or high-humidity exposure, an anodised finish variant (where available) provides additional corrosion protection. Avoid direct contact with strong acids or alkalis, which can degrade the surface over time.

Can I use this pulley in a CNC router or 3D printer motion system?

Yes. H-type pulleys with 12.7mm pitch are widely used in CNC router axis drives and larger-format 3D printer motion systems where higher torque transmission is needed compared to GT2 or T5 profiles. Ensure your motion controller and belt tension are set correctly to maintain positioning accuracy.

What is the difference between H10T and H30T in terms of pulley size?

More teeth means a larger outer diameter. An H10T pulley has a smaller pitch diameter and is suited for high-speed, lower-torque output positions, while an H30T has a larger pitch diameter and delivers more torque at lower output speed. Select based on your required speed ratio and the physical space available in your machine frame.
