5 steps tell you how to choose suitable casters

If you are first time to use casters then follow next 5 step can help you choose suitable casters.

First step —-Materials
       Industrial caster wheels material include: Rubber,Nylon,Polyurethane,Cast Iron,Elastic rubber etc. Different materials are available for different condition.
For example
* Polyurethane wheels are suitable for indoor and outdoor environment
* Nylon and cast iron wheels are suitable for outdoor ground as they can not protect ground well.
* Elastic rubber wheels can be used as hospital bed wheels,hotel trolley wheels,tiles and wooden floors where need protect floor and keep silent.
Second step —- Bracket
        In order to choose the right caster bracket,you must consider load weight request of the casters.
        E.g. In relatively quiet places such as supermarkets, hospitals, office buildings, clubs, etc., the ground is generally good, smooth and the goods being transported are relatively light,so use thin material stamping bracket is ok. In places where the noise is relatively large like factories and warehouses, it is more appropriate to use a high-pressure ( heavy duty casters )to make a thicker steel plate to make the wheel frame.
Third step —- Load capacity 
       Calculate the maximum load weight of the industrial casters so that ensure the casters are well protected.
       Corresponding formula: T=(E+Z)/M*N: “T” is the required load weight for a single wheel or caster; “E” is the weight of the transport equipment; “Z” is the maximum load weight; “M” is the number of single wheels and casters used. ; “N” is the safety factor (about 1.3-1.5)
Fourth Step—-Wheel diameter
       The larger the diameter of the industrial casters, the easier it is to push.The higher ability to load the weight, the protection of the ground from damage. Accordingly the price is higher than that of small diameter industrial casters.
Fifth—-Flexibility 
       The reasonableness of the turning radius directly affects the service life of the steering casters, which can better maintain the equipment and shock absorbing.
