81X Rooftop Chain

81X Rooftop Chain Lumber RT Chain

The 81x rooftop chain has a unique side-splitting function. This smooth roof style will help protect the handled wood from scratches and dents while reducing unnecessary dust accumulation in the chain mechanism. Cold forged solid rollers and solid bushings can significantly prolong the life of the chain. Specially selected alloy steel and computer-monitored heat treatment process ensure high strength and durability.

81X Rooftop Chain Lumber RT Chain

Sprockets fit our entire conveyor chain range.

81X Rooftop Chain Lumber RT ChainThe drive chain and the conveying chain are driven by sprockets. The uniform distribution of power depends on the precise transmission between the sprocket teeth and the chain rollers or bushes.

Because sprockets significantly impact the chain's life, all challenging sprockets (from casting to precision mechanical cutting) are manufactured according to strict tolerances and quality control. We also recommend that all customers replace the sprocket when replacing the chain to maximize the chain life.
