How to test the stiffness of the pu castor degree?

There is a very simple identification method, is to use the hammer, testing its hardness, if you buy wheel hard enough, so is the nylon wheel, on the contrary, if very soft, so is the plastic wheel. Universal wheel steering effect in the factory, in the car driving, need to bend, universal wheel has played a role. The height of the flat to the ground the installation height of polyurethane casters. To is, is highly not tablet plus the height of the wheel, is the support of eccentricity to the height of the wheel bearing and the height of the wheel radius is the actual height. Now there are a number of manufacturers, in order to save costs, called the plastic material production of castor nylon wheel, more than doubled, because the price of nylon than plastic, so the price difference is very big also. How to test the stiffness of the pu castor degree? Installation height, castor is polyurethane casters in use, the height of the ground after the installation of castor. Usually single wheel is the wheel radius, the height of the bearing center in the ground. Is the installation height of castor. Castor with stents, is to look at the use of stents is what style, scaffolding caster wheel installation height, including the height of the screw, with a flat have a fixed and steering 2 ways. Pu castor manufacturers usually flat car, the front two directional, two back turned, in this way, the user at the corner of easy to operate. Have a car with the use of the environment, high temperature, with the wheels of the high temperature resistant, load not too big. Uneven, with damping polyurethane casters that guarantee the safety of the goods, oily, with non-slip castor. Usually pu castor is according to the customer's usage environment and production, by their use. How to identify the nylon wheel? Therefore, there is a lot of quality problems. In order to let everybody to avoid fall for it, we will be showing some of the features of nylon wheel. In general, the color of the finished product is light yellow or milk white nylon round, as a result of nylon is high polymer material, so has high mechanical strength, can achieve the strength of the metal materials. Pu castor wholesale price of plastic material to produce castor, both from color and appearance with the nylon is very similar, even can be said to be the same. Based on the consideration of cost savings, so some dealers only value price and don't care about the quality. For some of the weight is not very large machinery, plastic wheel can be used, but for the capacity of large mechanical equipment, plastic wheel will not be able to use. ( ​ )
