Casters are used in a wide variety of applications. The right caster for the job may be the difference between a safe operation and a workplace disaster. However, it is crucial to understand the basics of how to measure casters before you can order the right size.
How much weight can 4 caster wheels hold?
A wheel is one of the most important components of any caster. It is not only the shape and diameter of the wheel that matters, but it also affects its weight rating. Wheels that are wider are better at spreading the load. Similarly, a smaller wheel has less vertical space but provides greater clearance.

Measurement techniques include measuring the width, the diameter, and the length of the wheel. This is a useful measure, as the right caster can help with mobility, and even the storage of heavy equipment.
Another measure to consider is the width of the bolt hole pattern. Generally, a 1- 3/4″ x 2- 7/8″ spacing is standard. However, it is important to note that this pattern cannot be changed.
In order to measure the stem, you can use a ruler or a caliper. You can also use a tape measure. If you decide to go with a caliper, be sure to get a digital caliper, as they are easier to use.
Measuring the length of the stem is a simple process. Measure the distance from the base of the stem to the tip of the stem horizontally. Also, be sure to measure the length of the spherical portion of the stem.
