Generally, we need to install the pu castor equipment can be roughly divided into two kinds: one kind is used for material flow of handling equipment, such as the wheelbarrow, logistics trolley, etc. ; And those are only for the convenience of mobile, the mobile is not frequent equipment, such as furniture, equipment, industrial equipment, etc. , we can call Jane mobility devices. The classification of pu castor what is commonly used in life? Industry's mobile ambulance bed will be equipped with a flexible universal wheel, its bearing capacity directly associated with equipment using quality pu castor, so considering the patient's life safety, of pu castor also need to be careful to choose. Often have a lot of friends is very confused, why the trolley is always running, unable to control the direction? In fact this is the result of wrong installation. Pu castor pu castor appeared to people carrying 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, pu castor is applied more and more widely in the whole world, all walks of life almost inseparable from the pu castor. Load ability to see the pu castor, we usually focus on the classification of pu castor dynamic load capacity, in order to be able to make pu castor has better applicability, suggest to choose pu castor single wheel load capacity design based on mobile devices and a third of the total load, namely, according to each device four pu castor configuration to consider. In the modern along with the continuous development of science and technology, the equipment is becoming more and more multifunctional and high utilization rate. Working in special high temperature or low temperature, or working environment temperature difference is very big, should choose metal wheels or special high temperature resistant wheels; Where the requirements to prevent the accumulation of electrostatic generation, had better use special anti-static wheel, also can choose metal wheel ( If the ground does not require protection, ; Work environment there are many corrosive medium, should choose to have good corrosion resistance of the wheel accordingly. High precision ball bearing special smooth and flexible operation, especially applicable to high-end equipment and quiet environment; Pu castor moving is also called dynamic load bearing ability, pu castor dynamic load 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. To: hard, narrow wheel than soft, wide wheels turn more easily. Pu castor manufacturer factory with pu castor is different from firms with polyurethane casters, tool for pu castor is different from a hospital bed with the light of polyurethane casters, shopping cart with pu castor requirements must be quite different from those for carrying heavy load in the factory of the pu castor. The ordinary bearing - Pu castor of sliding bearing is the simplest form of bearing or friction.
