Product Features: Anti-static 10 5-9Ω, quiet and wear-resistant without leaving traces, adaptable to uneven ground, low center of gravity, two-wheel design, flexible rotation
Polyurethane shock-absorbing damping blocks can effectively reduce vibration and maintain the stability of loaded items.

Purpose:
Testing deformation capacity

Condition:
1. Set up the caster on the testing machine.
2. Recording the capacity deformation ratio.
3. Lab temperature: 23° C

Testing method:
Set up the caster on the testing machine then exerting the pressure.

Standard:
After the static pressure testing for 3 minutes,

Result:
The static pressure load of this wheel is 0-220kg. When the load reaches 220kg, the spring compression of the wheel set is 9.3mm. After the pressure is released, the outer diameter deformation of the single wheel is 0.06. The rebound effect of the wheel set is good. The bearing rotates flexibly, without jamming or loosening.
