Do you know how big pu castor static load is

Static load: pu 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. To: hard, narrow wheel than soft, wide wheels turn more easily. Rotate wheel radius is one of the important parameters, short turning radius increases to the difficulty, too much will cause the wheels wobble and shorten the life. Do you know how much pu castor static load rotating radius is reasonable or not directly affects the service life of pu castor. Driving load: pu castor moving load bearing capacity is also called dynamic load, dynamic load of the pu castor is different due to the test in a different way of the factory, material of the wheel will have different and different, the key is to support the structure and quality can impact and shock resistance. Impact load: when the equipment has fundamental impact or vibration pu castor instantaneous load bearing capacity. Pu castor manufacturers installation height: refers to from the ground to the vertical distance between equipment installation position, the installation of the pu castor height refers to the remote big and pu castor base plate and the wheel vertical distance. Stand to center distance: refers to the vertical line to the center of the wheel core center rivet horizontal distance. Turning radius: refers to the center of the rivet vertical line to the outside of the tire on the edge of the horizontal distance, proper spacing of the polyurethane casters can be turned 360 degrees. Pu castor installation method such as three universal wheel is suitable for light load, the instrument can very good driving car in all directions, a straight line driving instrument car is not easy to control, in the case of this arrangement instrument has a tendency to tip over. Each have universal wheel and directional wheel are two such as this is pu castor commonly used arrangement, the arrangement of linear motion can be comparable with the motion curve. But exercise flexibility in narrow channels. The alternative is to use group instead of directional wheels, also put two single wheel installed on the same shaft. Between the wheels of the four directional wheel installation height slightly tall, it is cheap and fine pu castor arrangement method, linear driving is good, and also is relatively easy. In the case of this arrangement instrument car easy to overturn. High elastic polyurethane casters alternatives can be among the directional wheel wheel instead of, also is two single wheel installed on the same shaft. Two universal, directional instrument car in a straight line is good, and can turn flexibly, in this structure on flat ground, otherwise the instrument car easy to overturn. Alternative is to directional rotation as wheelset, also is two single wheel installed on the same axis. Four such universal wheel is suitable for narrow channel, because the instrument car in every direction can be a very good exercise. But straight instrument car is not easy to control the direction. In at least one direction of adding a lock on universal wheel device can improve the situation. Driving flexibility: factors affecting driving pu castor flexibility with stents of the structure and the selection of steel, the size of the wheel, wheel type, bearing, wheel driving the greater flexibility, the better, hard on the smooth ground, narrow wheel than flat soft wheels and effort, but on the uneven ground soft wheels and effort, but on the uneven ground soft wheels can better protect device and shock!
