● High quality raw material selection made rollers working lifetime 50000 hours on average.

● Long Life-Span & Energy Saving:resistance of roller rotating is 30% lower than that of national standards, which can save 40% power consumption per hour.

Cheap Inferior idler means:
Inflexible movement and more power to run $$ Quicken the wear and tear of belts $$
More placement(Be one year or just two weeks to go)$$
More downtime for maintenance$$
Inferior roller brings harms, endless ....
Inferior roller means low buying price, high running cost.
