Shock load: The instantaneous load-bearing capacity of polyurethane casters when the equipment is impacted or shaken by the load. Static load Static load Static load Static load: The weight that polyurethane casters can withstand at rest. The static load should generally be 5 to 6 times the exercise load (dynamic load), and the static load should be at least 2 times the impact load.
Adopting large-diameter bead discs, and the bottom plate, upper and lower bead plates are subjected to carbonitriding heat treatment, industrial polyurethane casters can greatly improve the rigidity and toughness of the bead discs, make the bead discs more flexible and easy to rotate, and can also improve the force performance. The structure of the shock-absorbing wheel is reasonable. The excellent shock-resistant and shock-resistant spring is selected. The industrial polyurethane caster prevents the wheel from being damaged due to vibration when working on uneven ground.
Steering: Hard, narrow wheels are easier to steer than soft, wide wheels. The turning radius is an important parameter for the rotation of the wheel. If the turning radius is too short, it will increase the difficulty of steering, and if it is too large, it will cause the wheel to shake and shorten the life. Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The proper spacing enables the polyurethane casters to turn 360 degrees.
The reasonable rotation radius directly affects the service life of polyurethane casters. Driving load: The load-bearing capacity of polyurethane casters when they are moving is also called dynamic load. The dynamic load of polyurethane casters varies depending on the test method of the factory, and also varies depending on the material of the wheel. The key lies in whether the structure and quality of the bracket can Resistant to shock and shock. High-elastic rubber iron core wheel made of good rubber, industrial polyurethane caster shock absorption performance characteristics have good tenacity and abrasion resistance.
