UHMW-PE Material Gravity Roller Applied on Filter Machine with Corrosion Resistant Feature

The gravity roller is mainly used on filtering machines with the function of avoiding filtering cloth to play and protect the cloth. The roller is not used on gravity conveyors. It is very weight, so can make the cloth of filter down enough.

Φ ≤ 300 mm; Tube Width ≤ 3300 mm. Customized as per your request.


The external bearing rollers of the filters are replaced frequently because of poor sealing, it is easy to immerse in water and cause bearing corrosion and damage. Hongda can customize internal bearing rollers or external engineering plastics bearing rollers. Which have good performances of waterproof and corrosion resistant, long service life and no need of regular maintenance and replacement.
