Rexnord Rex #40 ANSI Simplex Roller Chain 10ft

The Rexnord Rex #40 ANSI simplex roller chain is a precision-manufactured standard pitch roller chain complying with ANSI/ASME B29.1, the American National Standard for roller chains and sprockets that governs the most widely used chain drive standard in global industrial machinery. At pitch #40 (12.7 mm pitch), this chain covers the light-to-medium duty conveyor, feeder, and drive applications that represent the largest segment of industrial chain usage in Saudi Arabia's manufacturing, food processing, cement, and materials handling sectors. The 10-foot (approximately 3.05 m) section is the standard supply format allowing field cutting to exact length or loop formation for new drive installations and maintenance replacements.

Rexnord Rex chains are manufactured in the United States with solid roller construction — not stamped or welded rollers — giving Rex chains superior fatigue resistance and a rated breaking strength that consistently exceeds ANSI minimum requirements by 20% or more. The Rex #40 simplex chain's link plates are precision-punched and cold-worked to develop compressive residual stresses at pin hole edges, the primary fatigue initiation sites in roller chain under reverse bending load, extending chain life compared to non-cold-worked link plates. Pin and bushing clearances are held to tight tolerances to minimise articulation shock and noise at sprocket engagement — an important characteristic for drive chains on food processing lines and packaging machinery where smooth operation and low noise are production requirements.

In Saudi Arabia, Rexnord Rex roller chains are stocked and used by maintenance teams at SABIC's pelletising lines in Jubail and Yanbu where #40 and #50 chains drive pellet cooler conveyors and bagging system indexing drives. Saudi cement plants including Saudi Cement Company and Arabian Cement use Rex chains on raw material weighing conveyor feeders and clinker cooler chains throughout their facilities. The logistics and warehousing sector across Riyadh, Jeddah, and Dammam uses Rex chains on automated conveyor sorters and pallet handling systems in large distribution centres.

Razz Middle East supplies Rexnord Rex roller chains in standard 10-foot sections and bulk reels for Saudi Arabia's industrial maintenance procurement programmes. We stock the most common ANSI sizes from #25 through #100 and can supply connecting links, offset links, and matched sprockets to complete a chain drive package. Our team provides chain drive selection assistance — speed ratio, centre distance, sprocket tooth count — for new installations and drive upgrades.
