Traditional Flexibility:

       1. The casters should be flexible, easy and durable, and the rotating parts (footstand rotation, wheel rolling) should be made of materials with low friction coefficient or accessories assembled after special process treatment (such as ball bearings or quenching treatment)

2. The larger the eccentricity of the tripod, the more flexible the steering is, but the carrying capacity is correspondingly reduced.

3. The larger the diameter of the wheel, the more effortless it is to push, and it can better protect the ground. Large wheels rotate more slowly than small ones, less prone to heat and deformation, and more durable. Choose a wheel with a larger diameter as far as the installation height allows.

       Moving speed:

       Requirements for the speed of the casters: In the normal temperature environment, on a flat ground, the walking speed is not higher than 4.2 km/h, and there is a certain stop working state.

       Use environment:

       The selection should take into account the special environment of ground materials, obstacles, and residues (such as iron filings, high temperature, low temperature, high acidity, high alkalinity, oil and chemical solvents, and places requiring antistatic). Casters made of special materials should be selected for use in special environments.

       Installation Precautions:

       Flat-bottom movable casters: the installation surface must be flat, hard and not loose.

       Directional casters: The two wheels must be in the same direction and kept parallel.

       Screw casters: must be equipped with spring washers to prevent loosening.
