Universal casters are a kind of movable casters, and their structural features include directional rotation and rolling sliding. In the modern commercial field, universal wheels (universal casters) are widely used. When you walk into any large shopping mall or supermarket, you can see universal wheels (universal casters) everywhere. Take large supermarkets as an example. Consumers often push a cart when shopping in the supermarket. The four sliding points supported under the cart are universal wheels. Universal wheels (universal casters) can slide in any direction on the horizontal plane, which greatly facilitates shopping transportation. Consumers can easily push the shopping cart to slide in the mall.
Let's further analyze the structure of the universal wheel. Through careful observation, we can find that there are several parts: rollers, structural brackets, rotating bearings, center rivets, etc. The roller is a single wheel. The structural bracket includes axles, nuts, screws, and plugs. The rotating bearing is the key mechanism to realize the rotation of the roller direction. Usually there is a sleeve on the outside. There are also several different types of rotating bearings, including single-layer bearings, double-layer bearings, and double-row ball bearings. Choose according to actual application needs. The center rivet is also a key component. It is a bolt used to fix the rotating device. By tightening or loosening the center rivet, the directional rotation flexibility of the universal wheel (universal caster) can be controlled.
Universal casters are also called movable casters or universal casters. Different from the simple wheel structure of traditional casters, the wheels of universal wheels can rotate horizontally at all angles, so they have full-plane motion functions. The quality level of universal wheels (universal casters) was very low when they were first invented. They were often very brittle and not strong enough. Therefore, the failure rate of universal wheels in the past was very high, and the service life was generally less than one year. However, with the continuous improvement of modern industrial manufacturing technology, the manufacturing technology of universal wheels has been continuously improved. Today's universal wheels have quite good firmness and strength, and also have shock absorption functions, and are even equipped with electronic equipment to realize electronic control of equipment and instruments.
Of course, even if the manufacturing technology of universal wheels (universal casters) is further developed and the service life is extended, it will eventually lead to failures or damage during actual use. Once there is a problem in use, we need to master certain maintenance methods. Here are some introductions:
1. To inspect the universal wheel, check the driving condition of the caster, which directly reflects the overall quality. If there is an abnormal sound during driving, there may be greater friction at the connection. If there is vibration, there is a problem with the bearing. If there is a hiccup, it means that there may be foreign objects entangled between the shafts.
2. Check the wear of the wheel surface of the universal wheel. The degree of wear on the tire surface can reflect the environmental conditions of the place of use, such as whether there are sharp objects or wire ropes on the ground. If necessary, a bearing sleeve can be installed for the universal wheel (universal caster).
