Some Of Our Products
Frequently Asked Questions
Q: What materials are used for the tubes and shafts of the carrying rollers?
The roller tubes are made of high-quality Q235 Carbon Steel, while the shafts are manufactured using #45 Cold Drawn Round Steel, ensuring excellent structural integrity and strength.
Q: What dimensions and bearing sizes are available?
We offer rollers with diameters ranging from 76mm to 219mm and lengths from 190mm to 3500mm. Compatible bearing models include 6204, 6205, 6305, 6306, 6307, 6308, 6309, and 6310.
Q: How do the labyrinth seals improve roller performance?
The labyrinth seals at both ends completely seal the roller. This prevents grease and oil leakage while blocking external contaminants like dust and water, allowing the roller to operate smoothly under a fully sealed state.
Q: How do these carrying rollers help reduce operating costs?
By reducing belt wear and keeping the conveyor belt running in its proper track, our rollers extend the life of the belt. This minimizes maintenance man-hours and lowers the overall operating costs of the conveyor system.
Q: Can these rollers withstand harsh industrial environments?
Yes. With strong hardness, high wear resistance, and a heavy-duty Q235 carbon steel construction combined with reliable bearing protection, these rollers are built for long service life in demanding applications.
