How do you determine whether caster wheels are of good quality?

Casters should always operate smoothly and stably on the ground—but this is almost purely a theoretical ideal. In reality, casters frequently encounter brief, jagged surfaces when leaving the ground, or cross thresholds, tracks, and potholes. Consequently, when they suddenly become overloaded or when three-quarters of the casters lose contact with the ground, they must bear the entire weight of the furniture.
How do you determine the quality of casters?
Simple inventions are often significant, and casters are no exception. At the same time, a city’s level of development is often directly proportional to its use of casters.
1. Reciprocating wear test:
The caster reciprocating wear test simulates the rolling motion of casters during everyday use. Caster manufacturers must conduct a two-point test to verify whether there are any obstacles present. During the test, no casters or other components are allowed to come loose. At the end of the test, each caster should still be able to perform its intended functions normally. After the test is completed, the caster’s ability to rotate around its axis and its braking function should remain intact.
2. Measurement of rolling resistance and rotational resistance:
When the kingpin inclination angle is adjusted or its steering direction is controlled, a force must be transmitted to the kingpin inclination angle via an object to overcome the resistance. This resistance depends on factors such as: load-bearing capacity, wheel diameter, wheel material, wheel surface geometry, and the rotating magnetic field of the continuous casting machine.
3. Severe damage or loosening of rubber tires can lead to unstable rolling, air leaks, abnormal load distribution, and damage to the baseplate. By promptly replacing damaged tires and bearings, caster manufacturers can reduce cost losses caused by downtime resulting from caster failures.
4. After inspecting and repairing the wheels, make sure that all bolts and nuts are securely tightened. Where possible, use lock washers or self-locking nuts on all bolts. If any bolt becomes loose, tighten it immediately. If a wheel in the bracket becomes loose, the wheel may be damaged or will no longer rotate smoothly.
5. Static Load Test:
Casters should always operate smoothly and stably on the ground—but in practice, this is almost purely theoretical. Casters briefly leave the ground to traverse jagged surfaces, or cross thresholds, tracks, and potholes. Consequently, when they suddenly become overloaded or when three-quarters of the casters lose contact with the ground, they must bear the entire weight of the furniture.

What are the differences among different swivel casters?
These two types of casters, due to their different functions, also serve different purposes. Swivel casters are suitable for food transportation in restaurants, while non-swivel casters are better suited for food handling in environments with a higher degree of mechanization. Because the materials used in non-swivel casters are relatively harder, many factories prefer these casters—they’re far superior to the swivel ones.
Principle of Antistatic Casters
Electrostatic casters are typically made from conductive materials such as metal or carbon fiber. These conductive materials have excellent electrical conductivity, enabling them to quickly dissipate static charges to the ground and thus prevent their accumulation. In addition, electrostatic casters feature a special structural design that enhances their conductivity and grounding effectiveness.
