Measure the existing wheel before ordering, even when the equipment model is known.
1. Measure the outside diameter
Measure across the widest part of the tread. A worn wheel can be smaller than its original size, so record visible wear and send a photograph when possible.
2. Record width, bore and hub length
Measure the working tread width, the shaft or bearing bore, and the total installed hub length.
3. Confirm material and operating conditions
Specify Polyurethane, nylon or rubber together with floor condition, load, operating temperature and exposure to water or chemicals.
