A, easy start. Damping spring caster wheel is made of high quality polyurethane wheel core package, has the good elasticity and abrasion resistance, is put on the equipment use, motive force is small ( Such as 6 inch shock castor, in a single wheel load of 200 kg, motive force is 3. 6 kg) ; Second, the resistance to high speed. Castor wheels adopts double tapered roller bearing, in the process of high-speed traction can better prevent the wheels wobble, greatly reduces the noise, provide production workshop with a quiet environment for our production. Three, seal dustproof and anti-wind performance. Spring castor seismic spring completely sealed, extremely good dustproof and anti-wind to suitable for different options and requirements. Four, shockproof performance. Choose good impact resistance seismic spring spring castor, using large diameter bead plate orbit, and base plate, upper plate after heat treatment, can greatly improve the hardness and toughness of bead plate, make bead plate rotating more flexible, easily greatly improve mechanical performance, avoid the wheels on the concave and convex surface damaged by vibration. Use scope: kitchen equipment, mechanical equipment, heavy duty field operation platform, the material carrier, heavy duty frame, heavy warehousing equipment, heavy tool, such as wide application scope. 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. 4, 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. 5, 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. 6, absorbs the high frequency vibration and sound insulation performance is good, 7, in the air spring ontology and optional one orifice is set between the air chamber, can play a damping effect, such as aperture freedom of choice, necessary facility shock absorbers.
