Caster engineers teach you how to choose the casters

Caster tips to buy 1. Size: common castors diameter is larger, more effort to promote, the obstacle ability is better, because the casters were pioneered in the late 19th century western formed industrialization, so common castors in inches, such as China's supermarket trolleys are mostly with 5 inch, 4 inch casters. Currently popular on the market the caster size from 1 inch to 10 inch have, commonly used dimensions have 2 inch, 2.5 inch, 3 inches, 3.5 inch, 4-inch, 5 inch, 6 inch, 8 inch, 10 inch, often need to driven, such as adopting the 4 ~ 6 inch casters in the supermarket shopping cart, logistics trolley, tools, cars and so on is preferred. But the caster diameter is too general to make equipment gravity rise, increased costs, so you want to be considered. If the device does not need to push the current, such as furniture, refrigerators, just at the time to engage in health only need to move a, 3 inches below the casters can be selected. . bearing: with a diameter of casters, general manufacturers will produce several series for the different weight, such as light, medium, medium and so on, let the wheels and a bracket with different thickness, or material. Single wheel load should be given a certain safety coefficient, on the surface is smooth, the load of a single caster = (gross weight of equipment, loaded number of casters) x 1.2 (safety coefficient); if the ground is not flat, the algorithm, the load of a single caster = gross weight of equipment 83019 3, because regardless of what kind of uneven terrain. There is always at least three wheels and supporting equipment, this algorithm is equal to increase the insurance factor, more reliable, preventing insufficient bearing, resulting in castors life greatly reduced or cause an accident. In the Foreign capital company, the load is generally expressed in pounds, while the domestic use of the majority of kilograms, the conversion relationship is: 2.2 pounds = 1 kg. 3 wheel material: This is very important, generally have PU, TPR, PP, rubber, nylon, etc., as for the application of temperature, surface hardness, ground environment, etc.. 4 installation method: generally, light load can be used in the wire rod, insert rod, expansion rubber cover, heavy load is used in the bottom, or directly welded to the equipment. General large companies are very rich in installation. 5. Brake: in function, brake wheel, a brake bracket universal, both with brake for double brake, and tread brake, brake, brake, specific contact castor plant. 6 casters in the equipment layout. Layout is not the same, not only affect the cost, and promote the feeling is greatly different! 7. The stent selection: divided into directional and universal, the material is generally made of carbon steel, electroplating, such as zinc, copper, nickel, chrome plating, spraying, useful also stainless steel, 8. Choose brand casters: view of the world, the market share ranking is, the United States Department of Shun group (including Colson, Jiawei Jarvis, AOBEN Albion, 10 brand), German Tang Tak tente, the two brands and to do things more comprehensive, quality excellent performance, casters production has a long history, world casters leading enterprises. Enterprise.
