Local advantages that matter

• Immediate collection from Samrand, Pretoria CBD or Cape Town branches reduces lead time and shipping costs.
• VAT invoices and account quotes available for schools, universities and businesses requiring procurement documentation.
• Technical guidance on sizing, tooth profile selection, and installation to avoid downtime on your project.

Common profiles and what to use them for

We stock a range of profiles (HTD, AT, XL) and materials (rubber, polyurethane with steel or fibre cores). Below is a quick spec comparison to guide selection - for detailed options visit our collections to browse by category.

Sizing formulas and a quick example

Sizing the belt length for two pulleys: L = 2C + (Pi/2)(D1 + D2) + ((D2 - D1)^2 / (4C)) where L is belt length, D1/D2 are pulley diameters, and C is centre distance. For a simple HTD example: D1 = 20 mm, D2 = 60 mm, C = 100 mm - use the formula to calculate required belt length and then choose the nearest stocked standard length.

If you'd like us to verify sizes for a class or prototyping run, Request a Quote and include pulley diameters, centre distance and expected torque.

Selection guidance, accessories and compatibility tips

Match torque, pitch and material to your application

When choosing belts and pulleys, prioritize the correct pitch and tooth profile for compatibility with your motor and existing pulleys. Consider polyurethane belts for improved wear and reduced elongation in long-term projects. For classroom or repeated builds, keep spare belts and belt tensioners in a kit to reduce downtime.

Typical accessory bundles we recommend

• Belt + matched pulley set (same pitch and tooth count) for plug-and-play replacement.
• Tensioner or idler pulley to maintain correct centre distance under load.
• Clamping hubs, grub screws and shaft adapters for secure pulley mounting.

Troubleshooting common issues

Noisy drives: check misalignment and pulley wobble. Skip or slipping: verify pitch match and belt tension. Rapid wear: inspect for contamination, incorrect hub mounting or over-tensioning.
