Diamond American Standard Roller Chain Spare (D32101)

The Diamond American Standard Roller Chain Spare (D32101) is a top-tier industrial component designed for the most demanding mechanical and power transmission systems. With its robust 2-inch pitch (50.80 mm) and a wide 31.55 mm spacing between inner plates, this chain is built to withstand high stress and continuous heavy-duty usage across sectors like mining, agriculture, construction, and manufacturing.

Equipped with a maximum roller diameter of 28.57 mm and a strong 14.27 mm bearing pin, the D32101 ensures smooth power transmission and minimizes wear during operation. The chain’s reinforced inner and outer plates, measuring 48.20 mm and 41.60 mm in height respectively with a thickness of 6.30 mm, add to its structural integrity and fatigue resistance.

Boasting a projected bearing area of 6.38 sq.cm, it ensures efficient load distribution, enhancing the lifespan of both the chain and associated components. With a minimum tensile strength of 23,120 Kgf and an average weight of 9.91 kg per metre, the D32101 is engineered to perform reliably under extreme mechanical loads and harsh operating conditions.

Whether used for OEM integration or system upgrades, the D32101 chain spare offers unbeatable strength, high endurance, and long-term performance—making it the go-to choice for professionals who demand the best in roller chain technology.
