With the rise of the industrial revolution in modern times, more and more equipment need to move, screw caster is more and more widely used in all walks of life almost inseparable from casters. So what are the structural characteristics of casters? The following is a detailed introduction from seven aspects.

1. Installation height: refers to the vertical distance between the ground and the installation position of the equipment. The installation height of the caster refers to the maximum vertical distance between the caster bottom plate and the wheel.

2. Distance of support steering center: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.

3. Rotation radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The appropriate spacing makes the caster turn 360 degrees. Whether the rotation radius is reasonable or not directly affects the service life of casters.

4, driving load: casters in the moving capacity is also known as dynamic load, the dynamic load of casters because of the different test methods of the factory, but also different because of the wheel material, the key is whether the structure and quality of the support can resist impact and shock.

5. Impact load: the instantaneous bearing capacity of the casters when the equipment is affected by the impact or vibration of the bearing objects. Static load Static load Static load Static load: The weight that the casters can bear when they are at rest. Static load should be 5~6 times of exercise load (dynamic load) in general, static load should be at least 2 times of impact load.

6. Steering: hard and narrow wheels are easier to turn than soft and wide wheels. The radius of rotation is an important parameter of wheel rotation. If the radius of rotation is too short, it will increase the steering difficulty, while if the radius of rotation is too large, it will lead to the shaking and shorten the life of the wheel.

7, driving flexibility: factors affecting driving castor flexibility with stents of the structure and the selection of steel, the size of the wheel, wheel type, bearing, wheel driving the greater flexibility, the better, hard on the smooth ground, narrow wheel than flat soft wheels and effort, but on the uneven ground soft wheels and effort, But soft wheels protect equipment and absorb shock better on uneven ground!
