The choice of universal casters method and material used

Universal castor castor is the so-called activity, its structure allows level rotate 360 degrees. Castor castor is a general designation, including activities and fixed castor. Fixed castor no rotational structure, not horizontal rotation only vertical rotation. This two kinds of casters are generally collocation with, such as the structure of the trolley is in front of two fixed wheel, behind near the armrest is driven by two wheels. The materials and application of universal casters: 1, the materials have a variety of universal casters, the most common material is: nylon, polyurethane, rubber, cast iron and other materials; 2, used in mining, mechanical equipment, electronic equipment, medical equipment, engineering, decoration, textile, printing and dyeing, furniture, logistics equipment, storage, revolving cars, chassis, cabinets, equipment, mechanical and electrical, dustless workshop, production lines, large supermarket, and many other industries and various areas; How to select the appropriate universal casters: 1, choose universal wheel material: first consider using the size of the pavement, obstacles, and use the residual material on site ( Such as iron, oil) , environment conditions ( Such as high temperature and normal temperature or low temperature) And the wheels can bearing the weight of the different conditions, such as to determine the choice suitable wheel material. For example: rubber wheel can't acid, oil and chemicals, high-tech polyurethane modified nylon wheel, wheel, high temperature resistant round can apply to different special environment; 2, calculating weight capacity: in order to be able to calculate the load capacity of various universal wheel need must know the weight of transport equipment and maximum load and the number of single wheel and universal wheel used. A single wheel load capacity needed for the calculation is as follows: T = ( E+Z) / M * N, T = single wheel or wheels to loading weight; E = weight of transportation equipment; Z = maximum load; M = the number of single wheel and castor wheels used; Safety coefficient (N = About 1. 3 - 1. 5) ; 3, determine the wheel diameter size: universal wheel diameter are usually the more the more easy to drive, the greater the load capacity and at the same time, it is to protect the surface from being damaged, wheel diameter size first consideration should be given the choice of bearing and the weight of the load on the truck starting thrust to decide. 4, rotational flexibility: single wheel rotation, the more the greater the effort, needle roller bearings can carry heavier load, the rotational resistance is larger: single wheel mounted on ball bearings, can carry heavier load, turn the lighter, flexible and quiet;
