Rexnord Rex #120 ANSI Double-Strand Roller Chain 10ft

The Rexnord Rex #120 ANSI double-strand roller chain is a heavy industrial chain designed for the highest-torque conveyor and drive applications encountered in Saudi Arabia's cement, petrochemical, mining, and steel sectors. Operating at 38.1 mm pitch (the #120 designation equals 1.5-inch pitch under ANSI B29.1), the double-strand configuration doubles the rated working load compared to simplex #120, providing a combined minimum breaking load of approximately 230 kN in a single chain width that fits standard double-strand sprockets. This chain is the correct selection when the required transmitted horsepower or torque exceeds what is practical with simplex chain or when the application demands the redundancy of a parallel load path.

The double-strand design uses a common set of pins shared across both strands with matched inner and outer link plates precisely aligned to ensure even load sharing between strands. Rex's manufacturing precision in aligning strand-to-strand pitch ensures that both strands bear equal load at every sprocket tooth engagement, preventing the unequal loading that causes one strand to run tight while the other runs loose and leads to uneven wear and premature failure. The #120-2D chain's thick link plates and large solid rollers are designed for the abrasive, dusty environments typical of Saudi cement raw material handling, where chain wear life is a key maintenance cost driver.

In Saudi Arabia, heavy-duty double-strand ANSI chains of the #120 class are the standard chain specification for cement kiln feed elevator bucket chains, slat conveyor drives on clinker cooler discharge systems, and pan conveyor drives on raw material stockpile reclaim systems at Saudi Cement, Qassim Cement, Hail Cement, and YACCO facilities. SABIC's bulk material handling systems at Al-Jubail industrial city use #120 double-strand chains on reclaim bucket wheel conveyor drives. The Saudi phosphate and mining sector, centred in the Ma'aden industrial city at Ras Al Khair, uses #120 double-strand chains on concentrate conveyor and loading systems.

Razz Middle East supplies Rexnord Rex #120 double-strand chains to Saudi cement and mining maintenance teams as part of planned shutdown maintenance packages. We provide chain measurement and elongation assessment services, sprocket wear evaluation, and complete chain drive replacement kits — chain, sprockets, connecting hardware — for total drive renewal at scheduled turnarounds.
