PU Round Drive Belt — Reliable Polyurethane Power Transmission, Cut to Your Length

When a worn or snapped round belt brings your light machinery to a halt — a lathe, a textile drafting frame, a small conveyor — sourcing the right replacement in the right diameter and length shouldn't be a project in itself. This polyurethane round drive belt is stocked in 15 diameters and sold by the meter so you get exactly what you need, nothing more.

Each order is fulfilled as a continuous length of solid polyurethane (PU/urethane) round belt in a distinctive green rough-surface finish. Diameters range from Ø1.5mm (≈1/16") to Ø18mm (≈45/64"), and lengths are available from 1 meter up to 50 meters per variant. The rough surface texture is formed into the outer skin of the belt, not a coating, providing consistent grip across the full length.

Typical applications include light-duty conveyor drive systems, textile and sewing machine power transmission, woodworking equipment belt drives, and DIY or hobbyist machinery where a round-groove pulley system is used. The cut-to-length format also makes it a practical choice for custom loop fabrication via hot-splice or PU welding.

🔗 Compatibility: Designed for standard round-groove pulleys. Select the diameter that matches your pulley groove. Suitable for open-end runs or splice-joined loops.

✅ Key Features of These PU Round Drive Belts

📐 15 Diameters, One Listing — Ø1.5mm through Ø18mm covers the most common round-belt pulley groove sizes found on light industrial and hobbyist machinery.
✂️ Cut-to-Length Flexibility — Order from 1 to 50 meters; no minimum loop length required. Ideal for custom conveyor belt drive fabrication or stocking a maintenance supply.
🟢 Rough Surface for Positive Grip — The textured outer surface increases friction against pulley grooves, reducing slip in polyurethane round belt drive applications compared to smooth-finish alternatives.
💧 Moisture and Oil Resistant — Polyurethane construction resists water, light oils, and mild chemicals — a practical advantage over natural rubber belts in workshop or light production environments.
🔄 Hot-Splice Compatible — Ends can be fused using a standard PU belt welding tool to form a seamless continuous loop, making this belt suitable for closed-loop urethane drive belt setups.
⚖️ Consistent Cross-Section — Solid round profile maintains uniform diameter along the full length, ensuring even contact and predictable tension across the pulley groove.

⚠️ Note: This belt is sold as an open-ended length. To create a closed loop, you will need to splice the ends using a PU welding tool. If you are unsure which diameter fits your machine, measure the pulley groove width before ordering.

❓ Frequently Asked Questions

How do I choose the right diameter for my machine?

Measure the groove or pulley channel your existing belt sits in. The belt diameter should match the groove width closely. Our belts range from Ø1.5mm (≈1/16") to Ø18mm (≈45/64"). When in doubt, size down slightly — a snug fit generally provides better grip than a loose one.

How do I convert the diameter from mm to inches?

Divide the mm value by 25.4. Quick reference: Ø3mm ≈ 1/8", Ø6mm ≈ 15/64", Ø10mm ≈ 3/8", Ø12mm ≈ 15/32", Ø18mm ≈ 45/64". If you know your belt size in inches, multiply by 25.4 to find the closest mm diameter in our range.

How much load can a polyurethane round belt handle?

PU round belts are typically suited for light-to-medium duty power transmission. Load capacity depends on diameter, length, and pulley size. Larger diameters (Ø12mm–Ø18mm) generally handle greater tension. For heavy industrial loads, contact us to confirm suitability before ordering.

Can this belt be used outdoors or in wet environments?

Polyurethane is generally resistant to moisture, light oils, and mild chemicals, making it more suitable for damp environments than rubber alternatives. However, prolonged UV exposure or immersion in harsh solvents may degrade performance over time. For outdoor use, we recommend periodic inspection.

Is this belt compatible with standard round-belt pulleys?

Yes. These belts are designed for standard round-groove pulleys commonly found on light machinery, textile equipment, and conveyor systems. Match the belt diameter to your pulley groove diameter for proper seating and power transfer.

Can I join or splice the belt to make a continuous loop?

Yes. Polyurethane round belts can typically be joined using a hot-splice method or PU belt welding tool to form a continuous loop. Cut to your required circumference, then fuse the ends. This is a common technique for custom conveyor and urethane drive belt setups. The welding tool is sold separately.

What does "rough surface" mean and why does it matter?

The rough (textured) surface increases friction between the belt and pulley groove, reducing slippage under load. This makes it preferable over smooth-surface belts in applications where consistent grip is critical, such as light conveyor lines or textile drafting machines.

How do I calculate the length I need for a closed loop?

For a two-pulley system, the approximate belt length is: 2 × center distance + π × (pulley diameter) for equal-size pulleys. Add a small allowance (typically 10–20mm) for the splice joint. We recommend ordering slightly more than your calculated length to account for trimming and splicing.
