V-Groove Aluminum Drive Pulley — Reliable Power Transmission for DIY Automation

When your conveyor stalls, your motor drive slips, or your belt keeps jumping track, the culprit is often a mismatched or worn pulley. These V-groove aluminum drive pulleys are engineered for makers, small workshops, and automation hobbyists who need a dimensionally accurate, drop-in replacement or upgrade for their V-belt drive systems — without the lead time of custom machining.

Each pulley is machined from aluminum alloy, offering a lightweight yet rigid body. The groove profile measures 12.5mm in depth (single-groove variants) or 12.2mm (double-groove variants), with outer diameters spanning 40mm to 150mm (approximately 1.57" to 5.91") and bore widths ranging from 8mm to 55mm (approximately 0.31" to 2.17"). Both single-groove and double-groove configurations are available to match your belt count and load requirements.

Typical use cases include DIY conveyor belt systems requiring a compact V-belt drive pulley, small motor-to-shaft power transmission setups in maker labs and educational robotics, and replacement pulleys for light industrial automation equipment where aluminum V-groove pulleys reduce rotating mass.

⚙️ Compatibility: Designed for standard V-belts. Match your belt's top width and angle to the groove profile. Bore size and OD must align with your shaft and center distance. See variant options for exact dimensions.

✅ Key Features of These V-Groove Aluminum Drive Pulleys

🔩Aluminum Alloy Construction — Lightweight and corrosion-resistant body reduces rotational inertia while maintaining structural rigidity under continuous belt load.

📐Wide Size Range — OD from 40mm to 150mm (1.57"–5.91") with bore widths from 8mm to 55mm, covering a broad spectrum of V-belt drive configurations in a single product line.

🔄Single & Double Groove Options — Single-groove variants (12.5mm groove depth) and double-groove variants (12.2mm groove depth) available to match single or dual V-belt drive setups.

🎯Machined Groove Profile — Precisely formed V-groove ensures consistent belt seating, reduces belt wear, and maintains alignment under load for smoother, quieter operation.

⚡Drop-In Replacement Ready — Dimensioned to standard V-belt pulley conventions; select your OD and bore width from variant options for a direct fit to your existing drive system.

🏭Versatile Application — Suited for DIY conveyors, motor drive assemblies, educational robotics, light automation equipment, and workshop machinery upgrades.

❓ Frequently Asked Questions

How do I choose the right OD and bore width for my application?

Match the outer diameter (OD) to your required speed ratio and center distance. The bore width must match your V-belt's top width. Check your existing belt or drive system specs, then select the corresponding variant from the size options above.

What is the difference between single-groove and double-groove variants?

Single-groove pulleys (groove depth 12.5mm) are designed for drives using one V-belt. Double-groove pulleys (groove depth 12.2mm) accommodate two parallel V-belts, which increases power transmission capacity and provides redundancy. Choose based on your belt count and load requirements.

Is aluminum strong enough for my V-belt drive?

Aluminum alloy is well-suited for light to medium-duty V-belt drives, DIY conveyors, and motor drive assemblies. It offers a good strength-to-weight ratio and reduces rotational inertia. For heavy industrial loads exceeding the rated capacity of aluminum, a cast iron or steel pulley may be more appropriate.

Are these pulleys corrosion-resistant?

Aluminum naturally forms a protective oxide layer, providing good resistance to moisture and mild environmental exposure. For harsh chemical or saltwater environments, additional surface treatment may be advisable. Contact us to confirm suitability for your specific conditions.

Will this pulley fit my existing shaft and belt without modification?

Select the variant whose bore width matches your belt's top width and whose OD aligns with your drive ratio. The bore diameter (shaft hole) is listed in the variant options — verify it matches your shaft diameter. If your shaft requires a keyway or set screw, confirm compatibility before ordering.

Can I use these pulleys for a DIY conveyor or automation project?

Yes. These V-groove aluminum drive pulleys are commonly used in DIY conveyor belt systems, small motor-to-shaft power transmission setups, educational robotics, and light automation equipment. Select the OD and groove configuration that matches your belt and load requirements.

What V-belt profile is compatible with the 12.5mm groove depth?

The 12.5mm groove depth is designed for standard V-belt profiles with a matching top width. Common compatible profiles include A-section and similar metric V-belts. Always verify your belt's cross-section dimensions against the groove profile before installation.

These o rings are a great for my ear tunnels

These o rings are a great for my ear tunnels, always loosing one here and there, I always have a new ones in the drawer. Being silicone, don't have any reactions compared to standard rubber ones I purchased at hardware stores, plus much less expensive. Purchased 16mm I'd to use on 19mm tunnels, and stay on great, might be able to get away with 17mm rings, but really happy with my choice.

Will never order from these folks again

I waited a long time and that’s all I received was the eyebolt with no threaded rod attached to it

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.
