Shop by belt type
Each type opens its sizes, dimensions and how to identify it.
Quick size lookup
Belt type, section, length. We confirm the price and availability on WhatsApp.
How ordering works
No account needed for a once-off order.
Code, photo or measurements on WhatsApp.
A person confirms the part, the price and stock or lead time.
EFT or cash on delivery. Regular buyers: 30-day trade account. PO numbers welcome.
Our own delivery or courier. The delivery time comes with the quote.
Work with us
A free check of your critical drives, with a written report your planner can act on. Scope and travel are agreed before we come.
Every belt on your critical machines, in matched sets, labelled per machine, so the next breakdown is a quick swap.
Spares shops, co-ops, bearing shops and hardware stores: sell quality belts, pulleys and bushes with technical back-up down the road.
Why belts fail
Most belts don't wear out. They're killed by the drive they run on.
¼° for timing and poly-V belts. An offset of 9 mm over a metre is already ½°. Align properly
16 mm per metre of span, at the force the calculator gives you. Not "a thumb's worth". Tension properly
Gauge the pulleys at every belt change. Worn grooves wreck new belts in weeks. Gauge properly

Calculators
Every result can be sent to us on WhatsApp for a quote in one tap.
Service factor, section, pulleys, belt, centre distance, number of belts, tension, shaft load.
SpeedDriven speed, or the pulley you need for a target speed, with slip.
GeometryDatum length, nearest standard belt, arc of contact, adjustment range.
TensionStatic tension, deflection force, sonic-meter frequency, shaft load.
Timing beltsPitch diameters, belt teeth, exact centres, teeth in mesh.
CostSavings from cogged or synchronous belts, and the cost of waiting for a belt.

Fill this in and press Send on WhatsApp. It opens WhatsApp with your request written out: attach a photo of the belt markings and send.
Used a calculator? Its Send these results button fills the details in for you.
Yes. Photograph the markings on the old belt. If they're worn off, measure the pulleys' outside diameters and the centre distance and use the identify-a-belt calculator, or ask us to come and measure.
For speeds, lengths and geometry, yes: those are exact formulas. For the number of belts on a critical drive, the power rating per belt must come from the maker's tables. Send us the result and we'll check it against the manufacturer's data.
Yes, by our own delivery or by courier. You get a delivery time with your quote.
Yes. Timing belts, round PU belts and many others are made to length, and pulleys can be machined to your drawing.
