Polyurethane casters play an irreplaceable role in our lives, especially in various industries, such as factories, workshops, business, catering and other industries. So, how do you choose the suitable polyurethane casters?
1. casters material: first consider the use of the road the size of obstacles. The use of ground residues (such as oil, iron.) the environmental conditions (such as high temperature, normal temperature or low temperature) weight under different conditions and the capacity of the caster to determine the choice of material for casters. For example: the rubber wheel is not acid, oil and chemicals, super high strength polyurethane wheels, polyurethane wheels, nylon wheel. The steel wheel and high temperature wheel can adapt to different special environment.
2. calculation of bearing weight: in order to be able to calculate the various casters need bearing ability, must know the transportation equipment weight, maximum load and the number of single wheels and casters. The following calculation of a single wheel required load capacity: T= (E+Z) MXN; T= single wheel or caster required bearing weight; the weight of E= transport equipment; Z= maximum load; M = the number of single wheels and casters; the safety coefficient of N= (about 1.3-1.5).
3. decide the size of the wheel diameter. Generally, the larger the castor is, the easier it is to push, the greater the load capacity, and the better protection of the ground. The choice of the wheel diameter should first consider the weight of the load and the starting force of the moving vehicle under the load.
4., rotational flexibility: Polyurethane castor technology is constantly innovating. The bigger the single wheel is, the more laborer it will save. The roller bearing can load heavier loads and have greater resistance when rotating. The ball bearings with high quality on single wheel installation can bear heavier loads, and make the rotation more portable, flexible and quiet.
5.: usually soft and hard material casters with a caster nylon wheel, super high strength polyurethane wheels, polyurethane wheels, high strength synthetic rubber, iron wheel, wheel and pump wheel. Super high strength polyurethane polyurethane wheels in both indoor and outdoor ground vehicle, can meet your requirements of handling; high strength artificial rubber can used in the hotel. Floors. Medical equipment, wood flooring, tile floor and other requirements when walking noise quiet driving on the ground; nylon wheel. Iron wheel is suitable for uneven ground or iron and other substances on the ground; and the pump wheel is suitable for light load and pavement soft uneven places.
6. temperature condition: the situation of severe cold and high temperature has great influence on casters. The polyurethane wheels are flexible at the temperature of 45 degrees below zero, and the wheels are flexible at high temperature and 275 degrees.
