How to judge caster wheels quality

,

     When we intend to purchase casters wheels, we usual ask several of companies for compare price. At this point,we often find that the prices received for same casters are different high or low price. 

 
    Why is this happened ? In general, the material grade,labor cost and the surface treatment process of supplier's difference cause the production cost higher or lower
 
But as purchaser how to judge caster wheels quality?
 
1. From the appearance of the bracket of the caster, the surface of the steel plate bracket of the caster is beautiful, without burrs, and the thickness must be uniform, thus ensuring the quality of the load.
 
2. The bracket of the caster is galvanized: the bracket is used to prevent rust. The galvanizing process is generally used to check the galvanization of the caster bracket.
 
3. The welding of the caster bracket: the welding of the steel plate should be smooth. There should be no leakage welding. Leak point, etc.
 
4. The size of the caster wheels meet technical standard
 
5. Check the appearance of the wheels: the surface is smooth, no damage, uniform color, no obvious color difference
 
6. Check the overall effect of the casters: the universal wheel rotates, each direction is flexible, no obvious pause / stuck
