When the choose and buy industrial casters we should what?

We all want to consider when buying anything if we buy things for us, is reasonable; The same when the choose and buy our industrial castor also need to consider these factors: one, decided to carry the weight of the load, the size of the wheels, but also affect industrial caster wheel rotation, ball bearing applies to more than 180 kilograms heavier load requirements. Second, the use of field conditions choose round big enough to adapt to the scene of the rift. Consider using the size of the pavement, obstacles and other factors. Three special environment, each wheel to adapt to different work environment, choose good to adapt to the special environment. Traditional rubber not acid oil and chemicals, for example, if you want to apply different special environment, division of suitable high-tech, plastic, bakelite modified polyurethane tire iron and steel wheel is a good choice. Four, the larger the flexibility of the wheel rotation is the energy, the ball bearing can bear a heavy load, ball bearing rotation is more flexible but carrying a lighter. Five, the temperature limit of cold and heat are likely to cause trouble for a lot of wheels, casters, if using suitable special green grease, can make the castor is applicable to - 40 ° C to 165 ° C high temperature.
