1. The features of the stamped bearing seat include superior corrosion resistance. Both the roller and sealing parts are made of high polymer materials, which are highly resistant to corrosion. In corrosive environments, their service life can exceed that of ordinary drum rollers by 5 times or more.

2. 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 roller bodies for drum rollers are made of high polymer materials, which have mechanical properties similar to bronze, excellent wear resistance, and good self-lubricating properties without damaging the belt.

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