From the perspective of professional analysis which is more suitable for universal casters?

Universal wheel, adjust the foot manufacturers most need to purchase a castor and wheels friends want to buy cheap and fine things, but the low price is often the least desirable. Such examples abound in real life, so how to breach in the changing of social reality, then need professional analysis of castor, from professional perspective to consider the castor compatible or not. Castor castor is known to all known qualitative analysis is to support mobile devices and drive equipment, castor is present on the importance of big, its important, how to choose the high quality casters, here are from professional Angle analysis castor universal casters to choose skills: 1, the material of universal casters, wheels of material to consider work environment factors, first consider using the size of the pavement, obstacles, and use the residual material in the field ( Such as iron, oil) , environment conditions ( Such as high temperature, normal temperature or low temperature) And the wheels can bearing the weight of the different conditions, such as to determine the suitable wheel material. For example: acid, fat, or corrosive chemicals in the environment should choose the PU wheel, PP, nylon, and avoid using rubber wheel in the corrosive environment. Bearing weight: 2, in order to be able to calculate the carrying capacity of the various kinds of casters need, must know the weight of transport equipment and maximum load and the number of casters used, a single round of the bearing capacity calculation: T = ( E+Z) / M * N, T = bearing the weight of the single wheel to need; E = weight of transportation equipment; Z = maximum load; M = the number of casters used; Safety coefficient (N = About 1. 3 - 1. 5) 。 3, the size of the wheel diameter: the diameter of the wheel that bigger is usually easy to drive, the greater the load capacity is also at the same time also 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 start thrust to decide. 4, universal casters material soft hard: in principle, the hard tyre tread is suitable for the floor exercise in a soft and smooth, and a soft tyre tread in hard or rough surface rolling more flexible, including most of the outdoor ground. When choose the time of the wheel, take into account all the ground of the special situation: uneven, sink, threshold, terminal strip. The wheels is more soft, soft material can not only protect the ground against damage to itself, also can protect the caster and rubber wheel, especially high modulus rubber wheel, does not produce the noise, the maximum protection of the ground, and the wheels of the carbon steel is the hardest. Typically, PU wheel is a compromise choice, ground protection level is moderate, can bear the weight of the larger.
