Choose size: general caster wheel diameter, the greater the push, the more energy, the obstacle ability the better, because the castor first at the end of the 19th century the western industrialization, so castor generally in inches, such as China's most supermarket trolley with 5 inch, 4 inch caster wheel. The current market popular castor size from 1 to 10 inches, the size of the commonly used 2 inch, 2. 5 inch and 3 inch, 3. 5 inch and 4 inch, 5 inch, 6 ', 8 ', 10 ', etc. , often need to promote commonly, such as supermarket shopping cart, logistics trolley, factory using 4 ~ 6 inch caster is preferred. But too much caster wheel diameter can make equipment center of gravity rises, the cost increase, so must carry on the comprehensive consideration. If the device does not need to often push, such as furniture, refrigerator, etc. , choose 3 inches below the caster wheel can. See bearing: the same diameter of casters, general manufacturers can produce several series for different bearing, such as light, medium, medium, etc. , method is to make the wheels and stents have different thickness or material. Calculate the load of a single caster to offer certain insurance coefficient, relatively flat on the ground, a single caster wheel load = ( Equipment had been present on the caster and quantity) ×1. 2 ( Insurance coefficient) ; If the ground not level off, the algorithm for the total weight of a single caster wheel load = equipment present 3, because no matter what kind of uneven ground, always at least three wheels support equipment at the same time, the algorithm is equal to increase the coefficient of insurance, more reliable, to prevent the bearing is not enough, lead to greatly reduce or castor life lead to accidents. In foreign company, bearing generally expressed in pounds, and most domestic use kg and their conversion relations are: 2. 2 pounds = 1 kg. The wheel material: this is very important, generally have a PU, TPR, PP, rubber, nylon, etc. , as far as applicable, such as temperature, surface hardness, ground environment. Installation method: general light load can be used in the wire rod, rod, plastic expansion sleeve, overloaded with floor, or directly welded to the device. Brakes: from the function, the brake wheel, brake bracket wanxiang, both with brake is double brake, and tread brake, brake, brake, etc. The stent: divided into directional and universal, general with carbon steel material, can undertake various plating, such as galvanized, copper plating, nickel plating, chrome plating, spraying, etc. , useful also stainless steel.
