4, the hard or soft materials of caster wheel body: Usually the caster wheels are nylon wheels, super-polyurethane wheels, high-strength polyurethane casters, high-strength synthetic rubber casters, iron wheels. Super polyurethane caster wheels, high-strength polyurethane wheels are not only driven on the ground both in indoor and outdoor, but also meet your transportation requirements;
High-strength synthetic rubber caster wheel is able to apply to hotels, medical equipment, floors, wood flooring, tile and other require for a quiet walk on the ground;
Nylon wheels, iron caster wheels are for uneven ground or ground with iron and other substances; and cheer caster wheel is suitable for light load and road surface soft and smooth occasions.
5, the flexibility of caster wheel rotation: the larger single wheel, the more effort the rotation. Roller bearings can carry heavier loads and greater resistance when rotation: single caster wheel is installed on the quality (bearing steel) ball bearings, which can carry heavier the load, turn more lightweight and flexible.
6, the temperature conditions of caster wheels: cold and high temperature has a great impact on the caster wheels, such as polyurethane wheels can be rotating flexible and comfortable at low temperatures under minus 45 ℃, high-temperature caster wheel rotating at high temperature under 275 ℃ Light.
