ISO and DIN Dimensional Standards

Metric caster wheels are dimensioned to ISO and European DIN standards, with diameters, tread widths, bore sizes, and axle specifications measured in millimeters rather than inches. These replacement wheels are essential for maintaining equipment manufactured in Europe, Asia, and other regions that use metric specifications. Attempting to fit an inch-dimensioned replacement wheel into a metric caster fork results in improper fit, unsafe operation, and premature wear, making correct metric sizing critical.

Frequently Asked Questions About Metric Wheels

Check the markings on the existing wheel or caster fork. If dimensions are listed in millimeters (e.g., 125mm diameter, 12mm bore), you need a metric wheel. If the equipment was manufactured in Europe or Asia, metric sizing is likely. You can also measure the bore diameter with calipers. Common metric bores (8mm, 10mm, 12mm) do not have exact inch equivalents, so a metric wheel is the correct replacement.

This is not recommended. Even small dimensional mismatches between metric and inch specifications can result in loose fits, bearing problems, or wheels that bind in the fork. A 1/2-inch bore is 12.7mm, which does not match a 12mm metric bore correctly. Always use the correct metric replacement to maintain safe, proper operation.

We stock metric wheels in rubber, polyurethane, nylon, polypropylene, solid elastomer, and other common tread materials. Material availability varies by diameter and bore size. Contact our team for availability on specific material and size combinations.

The most commonly requested metric wheel diameters are 75mm, 100mm, 125mm, 150mm, 160mm, 200mm, and 250mm. These sizes cover the majority of European-manufactured carts, racks, and industrial equipment.

Metric Replacement Wheels: ISO-Standard Sizing for European and Imported Equipment

Our metric wheel catalog covers the most commonly needed sizes, including 75mm, 100mm, 125mm, 150mm, 160mm, 200mm, and 250mm diameter wheels in multiple tread materials. Bore sizes follow metric standards including 8mm, 10mm, 12mm, 15mm, and 20mm with appropriate metric bearings. Whether you are replacing wheels on European-made food service equipment, German-engineered manufacturing machinery, or imported industrial carts, our metric wheels provide a precise drop-in fit that maintains the original equipment specifications.

Metric replacement wheels are available in the same material range as our standard catalog, including rubber, polyurethane, nylon, polypropylene, and various polymer compounds. Material selection follows the same guidelines as inch-dimensioned wheels: choose the tread material based on your load capacity, floor type, temperature, chemical exposure, and noise requirements, then specify the correct metric dimensions to match your equipment. Contact our team if you need help cross-referencing a European part number to find the correct metric replacement wheel.
