key-quality-characteristics-of-idlers:
1. Energy saving - Rotational resistance(The main indicators that reflect the efficiency of conveyor rollers, reducing rotational resistance, can effectively improve the efficiency of belt conveyors and save energy)
2. Long lifespan, Low noise - Outer Diameter Radial Runout (Reflects whether the idler rollers operate smoothly; smaller outer diameter radial runout can reduce rotational resistance and extend the service life of the conveyor)
3. Durability - Dust resistance test, Water Pouring test, Water Immersion Test (Adaptable to various working environments, prevents dust and water from entering the rollers, extending their service life)
4. Reliability - Axial displacement amount (A lower axial displacement ensures long-term effective sealing performance and extends the service life of the conveyor)
