1. Calculate the load weight of caster

In order to be able to calculate the load capacity of various casters, the net weight of transport equipment, maximum load and the number of single wheel or caster used must be provided.A single wheel or caster load capacities as needed calculation is as follows: T = (E + Z)/M x N. T = load capacity required by a single wheel or caster;E = net weight of transportation equipment;Z = maximum load;M = the number of single wheel or caster used;N = safety coefficient (about 1.3 to 1.5).

2. Decide the material of the wheel or caster

Consideration on the size of road,obstacles,remaining substances on application area(such as iron scraps,grease),surrounding conditions and floor surfaces(such as high temperature or low temperature, humid;carpet floor,concrete floor,wood floor etc.)Rubber caster,PP caster,Nylon caster,PU caster,TPR caster and anti-static caster are applicable to different special areas.

3. Decide caster diameter

The larger the diameter of caster,the easier the movement and the larger the load capacity,which can also protect the floor from any damage.The selection of caster diameter should be decided by the load capacity requirement.

4. Decide the mounting types of the caster

In general,mounting types include Top plate fitting,Threaded stem fitting,Stem and Socket fitting,Grip ring fitting,Expanding stem fitting,Stemless fitting,it depends on the design of trasport equipment.
