1. Adopting precision bearings, high-quality grease and a lightweight design, its rotational resistance coefficient is far lower than the national standard, ensuring smoother operation. 2. The combination of multiple labyrinth seals and high-performance lip seals effectively blocks dust and moisture from entering the bearing cavity. 3. The sturdy steel pipe wall thickness and precise dynamic balance correction ensure stable operation without vibration. 4. The flexible rubber ring design and precise coaxiality reduce impact and wear on the conveyor belt. 5. Low-noise operation improves the working environment.
