Heavier sidebars, through-hardened pins, solid rollers, heat-treated alloy steel construction, and maximum tensile strength design.
The 81XHH conveyor chain is an extra heavy-duty engineered class chain designed for extreme material handling applications. It is widely used in forestry, sawmills, agriculture, paper mills, and heavy industrial conveyor systems where maximum strength, durability, and wear resistance are required.
This chain features heavier sidebars, through-hardened pins, and solid rollers to deliver superior performance under high load and harsh operating conditions. It is designed for long service life and reduced maintenance in continuous-duty systems.
81XHH chains are built for extreme-duty applications where standard and even heavy series chains are not sufficient. They provide higher tensile strength and better resistance to shock loads and wear.
These chains are commonly used in lumber mills, forestry conveyors, gypsum plants, grain handling systems, and other heavy industrial material handling operations requiring maximum reliability.
Heavier sidebars, through-hardened pins, solid rollers, heat-treated alloy steel construction, and maximum tensile strength design.
Used in forestry equipment, sawmills, lumber conveyors, grain handling systems, paper mills, and heavy industrial conveyors.
Provides maximum durability, higher load capacity, reduced elongation, and long service life in extreme operating conditions.
