Diamond American Standard Roller Chain Spare (D40101)

The Diamond American Standard Roller Chain Spare (D40101) is designed for industries where uncompromising strength, reliability, and endurance are essential. With a pitch of 63.50 mm (2½ inches) and a wide 37.85 mm width between inner plates, this roller chain spare stands out as a powerhouse component in high-load mechanical and transmission systems.

The robust roller diameter of 39.68 mm and heavy-duty 19.84 mm bearing pin enable smooth operation under significant mechanical stress. It is built with reinforced plates—60.30 mm inner plate height and 52.00 mm outer plate height, each with a thickness of 7.90 mm, ensuring optimal resistance to fatigue, wear, and impact forces.

With a projected bearing area of 10.75 sq.cm and an average weight of 16.26 kg per metre, the D40101 offers enhanced load distribution and durability, making it suitable for use in mining equipment, heavy manufacturing, bulk material handling, and other high-stress environments. Its minimum tensile strength of 36,070 Kgf guarantees reliable performance even under continuous, demanding operations.

Whether you’re upgrading a system or replacing a worn part, the D40101 delivers unmatched performance and longevity, meeting the high standards expected in critical applications.
