Polymer roller / Nonmetal Low-Noise Idlers

KDHI's nonmetal low-noise idlers use modified ultra-high-molecular-weight polyethylene shells, low-noise deep-groove ball bearings and V-type contact sealing. The design addresses running noise, corrosion, material adhesion and roller weight.

The design includes a damping sleeve and a ventilation groove intended to reduce vibration and bearing noise. The shell material resists water absorption and material adhesion.

Performance results vary between conveyor installations. Noise and energy performance varies with test distance, belt speed, load and installation conditions.
