Spring caster wheel wear resistance and shock absorption advantages

Spring castor wear-resisting performance is superior in the presence of water, oil and other wetting medium of working conditions, the wear resistance of polyurethane casters are often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but doesn't have to wear; Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, stadium track the runway, forklift truck crane dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Need to mention here is that to improve the low and middle hardness, the friction coefficient of polyurethane elastomer parts, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of polyurethane elastomer aluminum and graphite or silicone oil lubricant. Usually have nylon wheel, wheel super polyurethane wheel, high-strength polyurethane wheel, high strength synthetic iron, iron, cheer. Super polyurethane wheel, high-strength polyurethane wheel in both indoor and outdoor floor, can meet the requirements of your handling; High strength synthetic lugs can apply to hotels, medical apparatus and instruments, floors, wooden floor, ceramic tile ground for low noise quiet on the ground when walking driving; Nylon wheel, wheel which can be applied to uneven or there are materials such as scrap iron on the ground; While pep talk round applies to soft light load and road surface is not flat. Spring castor shock absorption advantages: 1, through the height control valve, can make the work of air spring height maintain under any load, also can make the spring under the same load with different heights, therefore, is not conducive to adapt to the environment in the structure of a variety of refuse. 2, air spring has nonlinear characteristics, can according to its characteristic line must be designed to be the ideal curve. 3, air spring stiffness varies with load, thus the natural frequency of vibration under any load constant, the performance of the spring mechanism with almost constant. 3, must according to the stiffness of air spring and with the help of a change for the volume of the air chamber on freedom of choice, and choice of very low. 4, the same air spring, can endure axial and radial load at the same time, also can transfer torque, and through the adjustment of the internal pressure, still can obtain different bearing capacity, thus can adapt many kinds of load must be. 5, and absorb the high frequency vibration and sound insulation performance is good,
