Rexnord Rex #80 ANSI Simplex Roller Chain 10ft

The Rexnord Rex #80 ANSI simplex roller chain is a heavy-duty chain drive component operating at 25.4 mm pitch and rated for high-torque conveyor, elevator, and industrial drive applications where #40 or #50 chains would be undersized for the load and speed requirements. The #80 designation follows the ANSI/ASME B29.1 standard, where the first digit represents the pitch in eighths of an inch, making #80 a one-inch pitch chain. This chain size is widely used in aggregate handling, mining, quarrying, cement, and steel plant material handling systems where the combination of high tension load capacity and moderate speed is the dominant drive requirement.

Rexnord Rex #80 chain is designed with thicker link plates, larger diameter solid rollers, and heavier pins compared to smaller ANSI sizes, resulting in a minimum breaking strength of approximately 58 kN — nearly four times the breaking strength of #40 chain. The chain's solid roller prevents collapse under side load, reducing the lateral forces transferred to sprocket teeth during chain engagement and extending both chain and sprocket service life in misaligned drive installations. Rex #80 chain is available with standard carbon steel construction for dry or lightly lubricated applications, and in stainless steel or nickel-plated versions for corrosive or food-processing environments.

In Saudi Arabia, Rexnord Rex #80 roller chains are used extensively in the cement sector — Saudi Cement Company, Qassim Cement, YACCO (Yanbu Cement Company), and Arabian Cement all operate raw material conveyor systems where #80 and larger ANSI chains handle the high-tension loads of aggregate and limestone conveyors. SABIC's raw material storage and reclaim systems at Jubail use #80 and #100 chains on bucket elevator and apron feeder drives. The construction and aggregate sectors in Riyadh, Mecca, and Medina use Rex chains in crusher plant conveyor systems during the ongoing giga-project construction phases.

Razz Middle East supplies Rexnord Rex #80 simplex chain alongside a full range of compatible sprockets, connecting hardware, and chain tensioners. We supply Saudi cement plants, EPC contractors, and industrial maintenance teams with ANSI chain in the quantities needed for annual shutdown maintenance programmes and emergency replacement stock, with fast delivery to all industrial regions of the Kingdom.
