Double V-Groove Aluminum Drive Pulleys — Reliable Power Transmission for O(Z)-Section V-Belts

When a slipping or mismatched pulley brings your machinery to a halt, every minute of downtime costs you. Whether you're a workshop owner maintaining a belt-driven lathe, a DIY builder assembling a custom conveyor, or a technician replacing worn drive components, finding a pulley that fits precisely and holds up under load is non-negotiable. These double V-groove aluminum drive pulleys are engineered for exactly that — a secure, repeatable fit with the dimensional accuracy that belt-driven systems demand.

Each pulley is machined from aluminum alloy, offering a balance of low rotating mass and structural rigidity. The double V-groove profile is sized for O(Z)-section V-belts, with an outer diameter (OD) ranging from 32mm to 60mm (~1.26" to 2.36") and a large OD/small OD step configuration of 40mm/32mm, 50mm/40mm, or 60mm/50mm. Bore diameter options span 8mm to 25mm (~0.31" to 0.98") to accommodate a wide range of shaft sizes.

These pulleys are well-suited for small motor drives, bench-top machinery, custom fabrication rigs, and light industrial equipment where a double-groove layout allows two belt runs simultaneously — ideal for applications like dual-speed setups, tandem drive systems, or redundant belt configurations.

⚙️ Compatible with O-section and Z-section V-belts. Verify your shaft diameter matches the selected bore size before ordering.

✅ Key Features of These Double V-Groove Aluminum Drive Pulleys

🔩Double V-Groove Profile

Two parallel grooves sized for O(Z)-section V-belts allow simultaneous dual-belt operation, enabling tandem drives or redundant belt layouts in a single compact pulley.

🪨Aluminum Alloy Construction

Machined from aluminum alloy for a combination of reduced rotational inertia and sufficient load-bearing strength — keeping your drive system responsive without unnecessary mass.

📏Wide Size Range

Available in three OD step configurations (40/32mm, 50/40mm, 60/50mm) and bore diameters from 8mm to 25mm, covering a broad range of shaft and belt combinations in one product line.

🎯Precision-Machined Bore

The bore is machined to close tolerances, ensuring a snug fit on the shaft and minimizing runout — critical for smooth belt tracking and reduced vibration at operating speed.

🔄Stepped OD Design

The large OD / small OD step geometry provides a natural belt guide shoulder, helping keep V-belts seated in the correct groove during operation.

🛠️Versatile Application Fit

Suitable for lathes, grinders, conveyors, custom fabrication equipment, and other belt-driven machinery where a compact, dual-groove aluminum pulley is required.

❓ Frequently Asked Questions

How do I choose the right bore diameter for my shaft?

Measure your shaft diameter with a caliper before ordering. The bore should match your shaft size exactly — a bore that is too large will cause runout and belt slippage, while one that is too small will not fit. Available bore sizes range from 8mm to 25mm. If your shaft uses a keyway, contact us to confirm keyway availability for your selected size.

What does the Large OD / Small OD specification mean?

This pulley has a stepped outer diameter — a larger flange OD and a smaller groove OD. For example, the 50mm/40mm variant has a 50mm large outer diameter and a 40mm small outer diameter. The V-belt rides in the groove at the smaller OD. The step acts as a shoulder to help keep the belt seated during operation.

Which V-belt sections are compatible with this pulley?

These pulleys are designed for O-section and Z-section V-belts, which are the same cross-section profile under different regional naming conventions (O is the ISO designation; Z is the DIN/European equivalent). Do not use with A, B, or other V-belt sections, as the groove angle and width will not match.

Can I run two belts simultaneously on this pulley?

Yes. The double V-groove design allows two O(Z)-section V-belts to run in parallel on a single pulley. This is useful for tandem drive configurations, dual-speed setups, or systems that require redundant belt paths for reliability.

Is aluminum strong enough for my drive application?

Aluminum alloy pulleys are well-suited for light to moderate duty belt drives — including bench-top machinery, small motors, conveyors, and custom fabrication equipment. For heavy industrial applications with sustained high torque or shock loads, verify that the pulley's load rating meets your system requirements. Contact us if you need clarification on suitability for your specific use case.

How do I confirm the pulley will fit my existing setup before ordering?

Check three dimensions: (1) bore diameter vs. your shaft diameter, (2) OD vs. your available clearance envelope, and (3) belt section — confirm your existing belts are O-section or Z-section. If you are replacing an existing pulley, note the OD, bore, and groove count from the old part and match accordingly. Still unsure? Use the contact form and we'll help you confirm compatibility.

Does this pulley come with a set screw or keyway pre-cut?

Set screw and keyway availability varies by size. Please contact us to confirm whether your selected bore size includes a set screw hole or keyway slot before placing your order.
