Polyurethane casters grill casters blow casters how to select the appropriate wheel 

 1, select the wheel material: First, consider the use of road space the size of obstacles, the use of on-site residue (such as iron, oil), in which environmental conditions (such as high temperature, room temperature or low temperature) and the wheels can carry the weight select the appropriate conditions to determine the wheel material. For example: rubber wheel can not be acid, grease and chemicals, super polyurethane wheel, high-strength polyurethane wheels, nylon wheel, steel wheels and high-temperature wheel can be applied in a special environment. 

 Calculate the weight-bearing: To be able to calculate the load capacity of a variety of casters, you must know the weight of transport equipment, the maximum load and the number of single wheel casters. A single wheel or casters required load capacity is calculated as follows: 

 T = (E + Z) / M × N: 

 --- T = single wheel or caster load capacity required; 

 --- E = weight of transport equipment; 

 --- Z = maximum load; 

 --- M = the number of single wheel and casters; 

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

 Polyurethane casters grill casters blow casters decide the size of the wheel diameter: usually the wheel diameter the greater the more easy to promote, and load capacity are greater than to protect the ground from damage, the choice of the size of the wheel diameter should first consider carrying weight and load the van starting thrust to decide. 

 4, the soft and hard choice of wheel material: usually the wheels nylon wheel, polyurethane wheel super high-strength polyurethane wheels, high-intensity artificial rubber tire, iron wheels, cheer round. Super polyurethane wheels, high-strength polyurethane wheels on the ground both in indoor and outdoor driving can meet your handling requirements; high-intensity artificial rubber tire can be applied to the hotel, medical equipment, floors, wood floor, tile, etc. requirements of walking noise and quiet on the ground traffic; nylon wheel, iron wheel applicable to the venue of the ground is uneven or there is iron in the ground substance; cheer wheel applies a light load and road soft uneven occasions. 

 5, rotational flexibility: single wheel the greater the rotation the more labor-saving roller bearings can carry heavier loads, the rotation resistance: a single round of installation quality (bearing steel) ball bearings, can carry a heavier load rotation is more portable, flexible and quiet. 

 6, the temperature conditions: cold and hot occasions on casters polyurethane wheel minus 45 ° C under low temperature, rotation flexibility, high temperature wheel rotation in the high temperature 275 ° C under light.
