The pu castor well is the best reward for the customer, the quality of the wheels have a unique point, is that they are round, no edges and corners, can evenly scrolling and rotate. This makes the bicycle, car, train and tram and other land transportation in highway, railway and rugged ground walk smoothly. In addition, the circular motion of the wheels makes it constantly the kinetic energy of the engine. In addition, many other inventions also rely on wheels. Since the invention of the wheel, handling and moving objects much easier. Wheels can only run on a straight line, however, for moving heavy objects to the direction of the change is still very difficult, castor later appeared to carry especially moving object has brought the era of the revolution, not only can easily carry, also can with any direction, greatly improving the efficiency. Recently with the rise of the industrial revolution, the more and more equipment need to move, castor is applied more and more widely in the whole world, all walks of life almost inseparable from the caster in the modern equipment with the continuous development of science and technology is becoming more and more multifunctional and high utilization rate, castor has become an indispensable part for the development of castor is more specialized and became a special industry. Using polyurethane elastomer coating is the continuous running 1800 small mouth ring and skirts into still not wear. 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. Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, universal wheel stadium track the runway, crane forklift dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Polyurethane pacify caster wheel with wear-resistant, industrial casters rolling resistance and tear resistance and so on are obviously better than noon tire; Same size of polyvinyl chloride resin rubber tire caster wheel load capacity is 6 ~ 7 times. Its production process to achieve continuous and automation, in the process of the production and use produces little waste. Check after repair wheels, determine whether the bolt and nut tightening, as far as possible at all to use the locking bolt washer or locknut. If is loose, tighten the immediately. If the inside of the bracket with the loose wheel will be to the rotation of the wheels was damaged or not.
