How to Identify the Quality of Casters

The appearance of the caster's support frame indicates that the steel frame surface is aesthetically pleasing, free of burrs, and the thickness must be even to ensure the quality of the load-bearing capacity.

2. Zinc-plated caster bracket: The bracket is commonly zinc-plated to prevent rust, ensuring the zinc coating on the caster bracket is even and shiny.

The welding of caster brackets: The welding of steel plates should be smooth and free of any gaps or incomplete welds.

4. Common sizes for casters.

Inspect the appearance of the casters: surface smooth, no dents, even color, no obvious color variation.

6. Inspect the overall effect of the swivel casters: When the top plate rotates, each ball bearing should make contact with the steel plate track surface, the force should be evenly distributed, rotation should be smooth, and there should be no noticeable pauses.

7. Inspect the quality of the wheel bearings: The wheels should not exhibit any noticeable skips when turning.
