Available in 4” and 5” diameters, CEMA B Rubber Disc and Steel Return Rolls are manufactured with Luff’s patented polymer endcap design, offering the ultimate in strength, durability and sealing performance. Steel shells are completely dipped in paint before assembly to prevent corrosion from inside. Rollers are built with a 20mm shaft, instead of the 17mm industry standard.
The polymer endcaps provide improved sealing arrangement, protecting the bearing from various environmental contaminants including dust and moisture. The Anti-lock Shield/High Moisture Seal is available as an option to further improve the bearing protection against moisture and contaminants.
Rubber Disc Returns provide a self-cleaning action to reduce build-up on the roller, prolonging the belt life of the entire conveyor system.
