product description

1: The roller rod is made of imported PP/PVDF strong acid and alkali resistant materials, and the inner tube can be customized with carbon fiber rod material to ensure that it will not be deformed after long-term use. The two ends are specially welded to make the two ends of the roller tightly and firmly bonded together. There will be no leakage.

2: The shaft is made of PEEK and carbon fiber rods. This material is resistant to high temperature, corrosion, abrasion, and has excellent mechanical properties. The surface is smooth and precision is stable after precision machining by CNC lathe. The shaft center is in interference fit with the wheel body and the gear, so that the roller and the gear can form a whole, and the transmission of the battery slice is more stable.
