As a mechanical part widely used in transportation and handling, casters are widely welcomed and loved by the market. In the actual use process, the selection of caster specifications is very important, because all the selection of caster specifications is for the final installation and use service. However, no matter how the choice of caster specifications is analyzed theoretically, the performance of different specifications of casters has not been understood in practice to be more accurate and objective.
The following is an example of actual use to introduce you to the use of caster specifications:
Example 1: A large supermarket in a certain city purchased 200 trolleys five years ago. The casters used in the trolleys are made of polyurethane wheels with a diameter of 3 inches and a design capacity of 70 kg per wheel. After five years of use. So far, the wear rate of 200 trolley casters is nearly 40%. The main causes of damage are rusty axles, deformation and distortion of brackets, and wear of casters. Comprehensive analysis shows that the actual use of supermarket trolleys is complex, such as overloaded use, improper use, overspeeding, etc., and the actual aging and wear of the casters have brought a greater loss rate and reduced service life. Example 2: A large logistics express company in a certain city purchased 300 hand-carried flatbed trucks five years ago. The caster specifications are nylon, the size is 3 inches, the single wheel bearing capacity is 70 kg, and the wear rate is nearly 20% so far. The main causes of damage are over-speed collision, rust of the caster bracket, abrasion of the wheel hub and so on.
Based on the above two examples, the specifications of casters used in various industries and fields are different, the effects of casters are different, and the service life of the casters is also different. The specific conclusion cannot be simply commented, and it is only used as a reference for everyone to purchase.
