Method for Inspecting and Maintaining Swivel Casters
Release time:
2020-02-04
Inspect the visible wear level on the tire tread. “Flat spots” on the tire tread may indicate the accumulation of foreign objects—such as threads, wire, or other debris—that could become entangled in the wheel. Remove the bolts and nuts from the wheel, then carefully clear away any debris. Check whether the wheel bearings are damaged. If the components are undamaged, you can reassemble the wheel and continue using it. However, if you frequently encounter situations where the wheel becomes entangled with debris, we recommend installing a debris-prevention cover to avoid such issues.
1. Inspect the visible wear level of the tire tread. “Flat spots” on the tire tread may indicate the accumulation of foreign objects—such as threads, wire, or other debris—that could become entangled in the wheel. Remove the bolts and nuts from the wheel, then clear out any debris. Check whether the wheel bearings are damaged. If the components are undamaged, you can reassemble the wheel and continue using it. However, if you frequently encounter situations where the wheel gets tangled with debris, we recommend installing a debris-prevention cover to avoid such issues.
2. Loose casters or jammed wheels can also cause “flat spots.” Proper maintenance and inspections—particularly checking the tightness of bolts, ensuring adequate lubrication, and replacing damaged casters—can enhance the equipment’s rolling performance and rotational flexibility.
3. Severe damage or loosening of rubber tires can lead to rolling instability, air leaks, abnormal loads, and damage to the baseplate, among other issues. Timely replacement of damaged tires and bearings can help reduce cost losses caused by downtime resulting from caster damage.
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 mounted in the bracket becomes loose, it could result in damage to the wheel or prevent it from rotating properly.

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.
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.
