1. Casters can be called directional casters and universal casters. The directional caster bracket is equipped with a single wheel and can only move in a straight line. Universal casters are made of a bracket that can turn 360 degrees and are equipped with a single wheel, so they can move in any direction at will.
2. Installation height: refers to the vertical distance from the ground to the installation position of the equipment. The installation height of the caster refers to the maximum vertical distance from the caster bottom plate and the edge of the wheel. Bracket steering center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.
3. Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The appropriate spacing allows the caster to turn 360 degrees. Whether the turning radius is reasonable or not directly affects the service life of the casters.
4. Steering: Hard, narrow wheels are easier to turn than soft, wide wheels. The turning radius is an important parameter for wheel rotation. If the turning radius is too short, it will increase the difficulty of steering. If the turning radius is too large, it will cause the wheel to shake and shorten its life.
5. Driving flexibility: The factors that affect the driving flexibility of casters include the structure of the bracket and the selection of bracket steel, the size of the wheel, the type of wheel, the bearing, etc. The larger the wheel, the better the driving flexibility. Hard, narrow wheels on stable ground require less effort than flat-sided soft wheels, but soft wheels on uneven ground save effort, but soft wheels on uneven ground can better protect equipment and absorb shocks. .
6. Driving load: The load-bearing capacity of the caster when moving is also called dynamic load. The dynamic load of the caster varies depending on the factory's testing methods and the material of the wheel. The key lies in the bracket. Whether the structure and quality can withstand impact and vibration.
7. Impact load: The instantaneous load-bearing capacity of the casters when the equipment is impacted or vibrated by the load.
8. Static load: the weight that the caster can bear in a stationary state. The static load should generally be 5 to 6 times the operating load (dynamic load), and the static load should be at least 2 times the impact load.
