Here is the pu castor real place? 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. Castor often the more the more easy to promote, the greater the load capacity, but also can protect the ground intact, wheel diameter size first consideration should be given the choice of bearing and the weight of the load on the truck starting under thrust to decide. Pu castor technology in the continuous innovation, single wheel rotation, the more the greater the effort, roller bearings can carry heavier load, rotational resistance is larger; Single wheel installed on the high quality ball bearing can bear a heavy load, turn the lighter, flexible peace. Pu castor is superior wear resistance, especially in the presence of water, oil and other wetting medium work condition, the wear-resisting performance is more outstanding, can reach several times to dozens times of general materials. In the case of hardness and abrasion resistance should be considered, pu castor better more metal casters. Through special formula of pu castor, its wear resistance than metal casters.
