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

 1, select the wheel material: First consider the size of the road, obstacles, using residual material on the site (such as iron, oil), in which environmental conditions (such as high temperature, room temperature or cold) and the wheel can carry the weight of the different select the appropriate conditions to determine the wheel material. For example: rubber wheel can not be acid, oil and chemicals, super-polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high-temperature wheel is able to apply different special circumstances. 

 2, calculate the load capacity: To calculate the required load capacity of a variety of casters, must know the weight of transport equipment, the largest single load and the number of wheels and casters. A single wheel or wheels required load capacity is calculated as follows: 

 T = (E + Z) / M × N: 

 --- T = single wheel or wheels need weight-bearing; 

 --- E = weight of transport equipment; 

 --- Z = maximum load; 

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

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

 Grill 3 casters casters polyurethane casters blow, decided to wheel diameter size: larger diameter wheels are usually more easy to push, the greater the load capacity but also better able to protect the floor from damage, wheel diameter size of the load should be considered first choice weight and load carrying vehicles starting next thrust to decide. 

 4, the choice of wheels hard and soft materials: nylon wheels are usually round, super-polyurethane wheels, high-strength polyurethane wheels, high-strength synthetic rubber tire, Iron, cheer round. Super polyurethane wheels, high-strength polyurethane wheels on the ground both in indoor and outdoor driving, can meet your transportation requirements; high strength synthetic rubber tire is able to apply to hotels, medical equipment, floors, wood floors, tile floor, etc. asked a quiet noise when walking on the ground running; nylon wheel, iron wheel for uneven ground or ground substances such as iron filings on the site; and cheer wheel is suitable for light load and road soft uneven occasions. 

 5, rotation flexibility: the greater the rotation the more labor-saving single-round, roller bearings can carry heavier loads, greater resistance to rotation: single wheel installed on the quality (bearing steel) ball bearing, can carry heavier loads , turning lighter, flexible quiet.
