We can see many industrial casters in factory. Occasionally, you may find yourself in a situation where you need a replacement caster wheel. The caster fork and frame is fine, or perhaps your application doesn't use a caster fork, and you just need a new wheel to replace an existing wheel. As long as you can remove the existing wheel, you’re in luck.
There are 4 critical measurements when it comes to replacing a wheel. These are the wheel diameter, wheel width, hub length, and bore diameter. Other dimensions will be discussed as well, but are primarily shown for clarification.
The wheel diameter is the distance measured across the side of the wheel. Occasionally the wheel will have its diameter and width stamped or molded into the wheel itself, so take minute to check and see if that is the case. If not, simply measure across the wheel. Bear in mind that wear can cause up to ½” of material loss, so if your current wheels are particularly worn you may need to round up to the nearest half inch. Because there are very standardized wheel sizes, this measurement can typically be taken with just a tape measure.
