Pu castor exactly how to use experimental data to tell you the truth, castor activities also is what we call the universal wheel, its structure is allowed to rotate 360 degrees; Fixed castor no rotational structure, can't turn. Usually two casters are generally use collocation, such as the structure of the trolley is in front of two fixed wheel, behind near the armrest is driven by two wheels. 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. From the ground to the vertical distance between equipment installation position, the installation of the castor height refers to remote the largest vertical distance and castor base plate and the wheel. Stand to center distance: refers to the vertical line to the center of the wheel core center rivet horizontal distance. When equipment has fundamental impact or vibration of the castor instantaneous load bearing capacity. Static load and static load static load and static load: castor can bear the weight of the under stationary state. Static load generally should exercise load ( Dynamic load) 5 ~ 6 times, static load should be at least 2 times the impact load. Hard, narrow wheel than soft, wide wheels turn more easily. Hard tyre surface is suitable for the floor exercise in a soft and smooth, and a soft tyre tread in hard or rough surface rolling more flexible, including most of the outdoor ground. When choose the time of the wheel, take into account all the ground of the special situation: uneven, sink, threshold, terminal strip. The wheel, the greater the more soft, more easily in orbit or similar cases rolling on the ground, the wheels of the soft can also protect the surface from being damaged. Rubber wheel, rubber wheel, especially high modulus does not produce noise, the maximum protection of the ground, and the wheels of the carbon steel is the hardest.
