Filter Machine Rollers with UHMW-PE Material and Any Sizes are Low
Filter machine 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.
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.
Φ ≤ 300 mm; Tube Width ≤ 3300 mm. Customized as per your request.

Test of UHMW-PE
|Project Name||Unit||Test Method||Test Result|
|Compressive Strength||MPa||ASTM D-638||≥42|
|Water Absorption||%||ASTM D-570||<0.01|
|Impact Strength||KJ/M2||ASTM D-256||≥140|
|Heat distortion Temperature||℃||ASTM D-648||85|
|Friction Coefficient||ASTM D-1894||0.11-0.17|
Under equal conditions, the service life of Hongda rollers is 2-3
times longer than that of common rollers.
