#120 Roller Chain
#120 roller chain is a specific size of roller chain that falls within the American National Standards Institute (ANSI) standards. The "#120" designation indicates the chain size or pitch, representing the distance between the centers of two consecutive pins. In the case of #120 roller chain, the pitch is 1.5 inches. This type of roller chain is commonly used in heavy-duty industrial applications where high strength and durability are essential for reliable power transmission. #120 roller chains are utilized in various machinery and equipment, including conveyors, manufacturing systems, and other heavy-duty applications that require the transfer of motion and power.
The #120 roller chain we offer adheres to the rigorous American National Standards Institute (ANSI) B29.1 specifications, ensuring consistent dimensions since these standards were established in 1930.
