Wheel material selection: 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 wheel can bear to determine the appropriate wheel material.
Industrial casters come in a wide variety of single wheel types, differing in size, model, and tire surface. Selecting the right wheel depends on several factors:
A. Load capacity.
B. Usage environment.
C. Various special climates, such as humidity, high temperature, or extreme cold.
D. Working environments containing chemicals, blood, grease, oil, salt, etc.
E. Requirements for impact resistance, collision resistance, and quiet operation.
How to choose the right caster for your use
I. How to choose the right wheel
1. Choosing wheel material: First, consider the size of the road surface, obstacles, substances remaining on the usage surface (such as iron filings, grease), environmental conditions (such as high temperature, normal temperature, or low temperature), and the weight the wheel can carry to determine the appropriate wheel material. For example: Rubber wheels cannot withstand acids, 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. Calculating load capacity: In order to calculate the load capacity required for 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 = Required load capacity of a single wheel or caster;
---E = Self-weight of the transport equipment;
---Z = Maximum load;
---M = Number of single wheels and casters used;
---N = Safety factor (approximately 1.3-1.5).
3. Determining wheel diameter: Generally, the larger the wheel diameter, the easier it is to push, the greater the load capacity, and the better the protection of the ground from damage. The selection of wheel diameter should primarily consider the weight to be carried and the starting thrust of the transport vehicle under load.
4. Selection of wheel material hardness: Generally, wheels include nylon wheels, super polyurethane wheels, high-strength polyurethane wheels, high-strength artificial rubber wheels, iron wheels, and pneumatic wheels. Super polyurethane wheels and high-strength polyurethane wheels can meet your handling requirements on both indoor and outdoor surfaces; high-strength artificial rubber wheels are suitable for use in hotels, medical equipment, floors, wooden floors, and tiled surfaces where quiet operation is required; nylon wheels and iron wheels are suitable for uneven ground or ground with iron filings; pneumatic wheels are suitable for light loads and soft, uneven surfaces.
5. Rotational flexibility: Larger single wheels are easier to rotate, roller bearings can carry heavier loads, and the resistance during rotation is greater: Single wheels installed with high-quality (bearing steel) ball bearings can carry heavier loads, rotate more easily, and are flexible and quiet.
6. Temperature conditions: Extreme cold and high temperatures have a great impact on casters. Polyurethane wheels rotate smoothly at low temperatures of -45℃, and high-temperature wheels rotate easily at high temperatures of 275℃.
