Metric V-Belts (SPZ, SPA, SPB, SPC)

If your equipment was built to European or international standards, chances are it calls for metric V-belts. Whether you're maintaining imported machinery, running a production line, or stocking your shop with the right inventory, we make it simple to identify, locate, and order the exact belt you need. At V-Belt Global Supply, finding the right metric V-belt is quick and hassle-free.

What Are Metric V-Belts?

Metric V-belts follow the international sizing system (measured in millimeters) rather than the fractional-inch system common in North America. They're the standard on equipment manufactured in Europe and much of the rest of the world, which makes them essential for anyone servicing imported pumps, motors, compressors, and industrial drives.

These wrapped belts use a narrow wedge profile for high power transmission in a compact footprint, and they're identified by a two- or three-letter code (SPZ, SPA, SPB, SPC) followed by the length in millimeters.

Metric V-Belt Sizes: SPZ, SPA, SPB, SPC

The four standard cross-sections cover everything from light-duty to heavy industrial drives. Here's how the metric V-belt sizes break down by top width:

  • SPZ – The smallest profile (10mm top width), ideal for compact, lighter-duty drives.
  • SPA – A step up (13mm top width), balancing size and power for a wide range of machines.
  • SPB – A heavier profile (16mm top width), built for demanding industrial applications.
  • SPC – The largest (22mm top width), engineered for high-horsepower, heavy-duty drives.

Each belt is measured by its pitch length in millimeters. An SPC5000, for example, is an SPC profile with a 5000mm pitch length. Knowing your profile and length is all it takes to place a confident order.

Metric V-Belt Conversion Made Easy

One of the most common questions we hear involves metric V-belt conversion, matching a metric belt to its fractional (inch) equivalent, or vice versa. While the profiles are similar, metric and inch belts aren't always directly interchangeable, and using the wrong one can cost you performance and belt life.

If you're unsure whether your drive needs a metric or classical belt, don't guess. Our team cross-references V-belt sizes in metric and inch systems every day, and we're glad to help you land on the right fit.
