How To Choose Caster Wheels

1. Select the wheel material: first consider the size of the road surface, obstacles, residual substances on the use site (such as iron filings, grease), environmental conditions (such as high temperature, normal temperature or low temperature) and the weight that the wheels can carry. conditions to determine the selection of suitable wheel material. For example, rubber wheels are not resistant to acid, grease and chemicals, while super polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high temperature wheels are suitable for different special environments.

2. Calculate the carrying weight: In order to be able to calculate the load capacity required by various casters, it is necessary to know the self-weight of the transport equipment, the maximum load and the number of single wheels and casters used. The required load capacity of a single wheel or caster is calculated as follows:

T=(E+Z)/M×N:

---T=The required bearing weight of a single wheel or caster;

---E = self-weight of transport equipment;

---Z=maximum load;

---M = the number of single wheels and casters used;

---N = safety factor (about 1.3-1.5).

3. Determine the size of the wheel diameter: Generally, the larger the wheel diameter, the easier it is to push, the greater the load capacity, and the better the ability to protect the ground from damage. The selection of the wheel diameter should first consider the weight of the load and the starting thrust of the truck under the load. to decide.

4. The choice of hard and soft wheel material: Usually the wheels include nylon wheels, super polyurethane wheels, high-strength polyurethane wheels, high-strength artificial rubber wheels, iron wheels, and inflatable wheels. Super polyurethane wheels and high-strength polyurethane wheels can meet your handling requirements whether they are running on indoor or outdoor ground; high-strength synthetic rubber wheels can be used in hotels, medical equipment, floors, wooden floors, tile floors, etc. It is required to drive on the ground with low noise and quiet when walking; nylon wheels and iron wheels are suitable for places with uneven ground or iron filings and other substances on the ground; while inflatable wheels are suitable for occasions with light load and soft and uneven road surface.

5. Rotation flexibility: the larger the single wheel, the more labor-saving it is to rotate, the roller bearing can carry heavier loads, and the resistance during rotation is larger: the single wheel is installed with high-quality (bearing steel) ball bearings, which can carry heavier loads , the rotation is lighter, flexible and quiet.

6. Temperature conditions: Severe cold and high temperature have a great impact on casters. Polyurethane wheels can rotate flexibly and freely at a low temperature of minus 45 °C, and high temperature resistant wheels can rotate easily at a high temperature of 275 °C.

Special attention: Because 3 points determine a plane, when the number of casters used is 4, the load capacity should be calculated as 3.
