If a single caster wheel load to given a coefficient of insurance, a local surface is quite smooth, the load of a single caster = ( By the number of castor total weight on the installation of equipment * 1. 2 ( Insurance coefficient) ; If uneven ground, the algorithm is the total weight of the load of a single caster = t device, because no matter what kind of uneven ground, always have at least three wheels supporting the equipment at the same time, this algorithm is equivalent to increase the coefficient of insurance, more reliable, prevent bearing is insufficient, lead to a drop in castor life or accident. Korean directional casters when choosing castor, we first need to observe its flexibility and temperature limit. As we all know, the bigger the castor, the more it. Ball bearing can be carrying overloaded, ball bearing can be more flexible but lighter to rotate. Cold and hot weather can bring trouble to many wheels. If you use castor, can be used. Evergreen special grease can make the castor applies to 40 ℃ ~ 165 ℃ high temperature. According to the requirements of the caster and use, the combination of the Chinese aesthetic idea, pu castor products is not only transmit power products, but also the combination of strength and beauty. Conventional model inventory sufficient, spot sales, effectively shorten the production cycle, reduce the pressure of customer inventory. Using high quality raw materials, advanced production equipment, efficient production line, strict quality control, to ensure that each of the castor high quality. The second is to consider castor field and use of the environment, choose the wheels of the big enough to adapt to the scene of the crack. Consider the size of the road, the influence of the obstacle factors such as; Each wheel to adapt to different working conditions, choosing the most suitable for the special environment of the wheel. Castor choice depends on the carrying capacity of the castor, determine the weight of the load, the size of the wheels, also affect the rotation of the industrial casters, ball bearing is suitable for the overloading requirement more than 180 kg. / news_149。
