Determination of caster material
  ① The rubber, PU or super synthetic rubber casters, which are of wear resistance and good elasticity, are applicable to the rough ground.
  ② The metal or tailor-made high temperature resistant casters are applicable to the working environment of high temperature, low temperature or sharp temperature difference.
  ③ The anti-static or metal casters are applicable to the locations with the anti-static requirements, preferably.。
  ④ The nylon or PU casters, with good corrosion resistance, are applicable to the working environment containing a high amount of corrosive mediums.。
  ⑤ The synthetic rubber or PU casters are applicable to the working environments with muting requirements.。


Definition of load capacity of single caster
Load capacity of single caster=1.4×(G dead weight+G carrying capacity)/M

Rotation flexibility
The roller bearing can carry a heavy load, but the rotation resistance is high. The ball bearing can carry a heavy load and can freely and flexibly rotate without any noise. The large caster can be flexibly driven on a stable ground.The hard and narrow caster can be easily moved than the flat and soft one. The soft caster is labor-saving and can produce better damping effect on the uneven ground.

 

Swerving flexibility
The caster will be difficultly swerved if the rotating radius is too small, while it will be vibrated and its service life will be shortened if the rotating radius is too large. The hard and narrow caster will be more easily swerved than the soft and wide one.


Temperature situation
The PU caster can freely rotate at the temperature as low as -45℃, while the high temperature resistant caster can freely rotate at the temperature as high as 275℃.
