Three methods to determine the quality of medium-sized casters

To determine the quality of medium-sized casters, you can consider the following three methods:

Observe the quality of the appearance: check the smoothness and uniformity of the surface of the casters, and whether there are any obvious flaws or damages. Good quality casters will usually have a shiny surface with no obvious pits or scratches.

Test the wheel’s abrasion resistance: Place the caster on a flat surface with an appropriate load (e.g., put something heavy on it) and perform a rolling test. A good medium-sized caster should be able to roll smoothly, without snagging or shaking, and be able to withstand long periods of use without wearing out.

Check the materials used and the manufacturing process: Good quality medium-sized casters tend to use high-quality materials such as wear-resistant rubber, polyurethane or reinforced nylon. In addition, the manufacturing process can also have an impact on the quality of the caster. Check that the connecting parts and bearings of the casters are sturdy and show no signs of looseness or deformation.

Considering the above three methods comprehensively, you can determine the quality of medium-sized casters more accurately. Of course, you can also refer to the evaluation of other consumers and the certification information of professional quality inspection organizations.
