The Diamond American Standard Triplex Chain (D20103) is built to handle high-load, high-torque applications with precision and resilience. With a pitch of 31.75 mm (1¼ inch) and an inner plate width of 18.90 mm (3/4 inch), this triplex chain ensures smooth, consistent operation even under heavy mechanical stress.
Its roller diameter of 19.05 mm and bearing pin diameter of 9.53 mm allow for efficient motion transfer and reduced friction. The inner and outer plate heights of 30.10 mm and 26.00 mm, respectively, with 4.00 mm plate thickness, provide exceptional durability and impact resistance, especially in environments with continuous motion and high shock loads.
Measuring 113.00 mm across the bearing pins and weighing 11.43 kg per metre, this chain offers excellent stability and extended service life. The tensile strength rating of 27,090 kgf guarantees dependable performance for applications such as material handling systems, conveyors, and heavy machinery.
