Built for maximum durability and strength, the Diamond American Standard Roller Chain Spare (D48101) is engineered to meet the needs of high-load, high-performance industrial environments. With a pitch of 76.20 mm (3 inches) and a wide 47.35 mm spacing between inner plates, this roller chain spare offers outstanding stability and power transfer for heavy-duty operations.

Its massive 47.63 mm roller diameter and robust 23.80 mm bearing pin diameter are designed to withstand immense mechanical stress and wear, while thick plates (8.80 mm each) add to the chain’s fatigue resistance and service life. The chain features plate heights of 72.30 mm (inner) and 62.40 mm (outer) for additional strength and structural support.

With a projected bearing area of 15.90 sq.cm, the D48101 ensures optimal load distribution, reducing friction and extending operational longevity. Weighing 23.63 kg per metre, this chain is built for serious industrial use in applications like mining, steel production, bulk material handling, and large-scale manufacturing.

Offering an exceptional minimum tensile strength of 53,050 Kgf, this roller chain spare delivers unmatched reliability and resilience under heavy cyclic loads and extreme conditions, making it a top-tier choice for mission-critical mechanical systems.
