C131 Chain - 3.075" Pitch Cast Combination Chain

C131 chain is a 3.075" pitch, cast combination chain and is one of the most common sizes in this chain class! Most commonly found in grain elevators or lumber mills, the C131 chain possesses excellent strength, with an average tensile rating of 32,400 LB. The C131 chain is also popular in sugar mills, flight conveyors, live-bottom trucks, and more. Construction-wise, the C131 chain has cast inner links (block) and mild steel pin links to benefit withstanding gritty applications while at an economical price point and upholding tensile strength. The chain can operate bi-directionally due to the links being symmetric and can be used in abrasive or non-abrasive applications.
