1. The pressed bearing seat boasts excellent corrosion resistance. Both the roller body and the sealing components are made of high polymer materials, highly resistant to corrosion. In corrosive environments, its service life can exceed that of a standard roller by a factor of 5 or more.

2. The roller bodies are available in two main materials: MC nylon and polyurethane, chosen based on the characteristics of corrosive substances in the operating environment. They are wear-resistant and have a long service life. The high polymer material specifically for roller bodies has mechanical properties similar to bronze, offering excellent wear resistance and good self-lubricating properties without damaging the belt.

3. Reasonably structured with reliable sealing. The drum features two sealing systems, high manufacturing precision, and is coated with special lubricant within the gaps, effectively preventing dust, gases, liquids, and other corrosive mediums from entering the drum and damaging the bearings. Lightweight with low rotational inertia.
