Polyurethane casters in abrasion resistance, rolling resistance and tear resistance is superior to the tire same size of the polyvinyl chloride resin rubber tire caster wheel load capacity is 6 ~ 7 times its can achieve continuous production process and automation, produces little waste in the process of the production and use, and more importantly waste tire part of the body can be recycled as other polyurethane products. What are the advantages in wear resistance of polyurethane casters? Oil resistance polyurethane ( PU) In many of the polymers on the environmental impact have excellent resistance ability. Its stability in the oil and solvent are better than ordinary rubber at all. Choose suitable wheel rack first consider bearing the weight of the castor, such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor is good, smooth lighter, and handling of goods ( Each trundle bearing in 10 - 140公斤) , suitable to select (with a thin plate 2 - 4毫米) Stamping wheel rack plating, the wheel frame is light, flexible operation, quiet and beautiful, the plating wheel frame in accordance with the ball bearing arrangement is divided into double row bead and single bead. High elastic polyurethane casters metal materials such as steel, although very hard, but does not have wear-resisting; 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. Don't need to add carbon black and some have carcinogenic effect of rubber compound, is the ideal material for manufacturing tire tread. The biggest characteristic of polyurethane casters is within the scope of the hardness of the high elasticity, good mechanical strength, oil resistance and ozone resistance, good low temperature performance. Polyurethane ( PU) Polymers with high modulus, high intensity and high tensile rate of these properties make casting polyurethane parts with good toughness and durability. Polyurethane (pu castor manufacturers compression performance PU) Pre polymers with rather than ordinary rubber hardness, has a much higher bearing capacity. This kind of high bearing capacity and excellent abrasion resistance and toughness makes the combination of polyurethane in industrial solid tires and industrial application of roller advantage is very outstanding. Tear strength, tear strength used in the actual evaluation of these elastomers ability of resistance to the development of fracture in practical applications, especially involved of the use of impact wear, high tear strength is important, casting polyurethane PU elastomer in this respect than traditional rubber) is preferred. ​ Market price of pu castor foot bearing if use suitable special green grease, can make the foot bearing was used 40° & C to 165 deg. C high temperature when hair repair idea, main bearing of crankshaft and connecting rod bearing selection should be based on repaired crankshaft main journal, connecting rod shaft neck size to select the appropriate size, category of the bearing, and ensure the crankshaft main journal and the main bearing, with the connecting rod journal and connecting rod bearing clearance. The wear resistance of high elastic polyurethane casters are often several times to dozens times of ordinary rubber materials. Will not cause environmental pollution and its manufacturing process simple - - - - - - - Liquid pouring shape, belongs to the new no cord casting wheel, thus known as the 21st century green tires, polyurethane wheels, will be the future developing trend of the automobile tires, has broad application prospects in auto industry. Polyurethane wheels, it is a kind of a material between general rubber and plastic, this is by far the most resistant elastomer, and non-toxic to human body, and can completely biodegradable.
