4000 Series Cement Chains
Available from U S TSUBAKI Inc
The Union® Chain Division has developed a truly remarkable line of bucket elevator chains designed especially for service in cement plants. These chains provide the highest ultimate and fatigue strengths available for this application. In addition, our innovative barrier seal design in the 4000 Series Chains helps prevent abrasive materials from entering and attacking the chain joints.
The Union® 4000 Series Chains are made of specially selected alloy steel, and they possess ultimate strength ratings approximately 45% higher than competitive brands. A special piercing technique developed by U.S. Tsubaki makes exceptionally smooth pitch holes for high interference fits. This piercing method, combined with shot peening, yields maximum fatigue strength and protects against failure—even when chains are challenged by the most severe applications.
Barrier Seal Design for Longer Wear Life
The 4000 Series Chain bushings extend beyond the inside sidebar to establish a barrier. This virtually eliminates abrasive material from entering the pin/bushing joint area. This heavy duty hardened part will not wear out prematurely, and it will not separate from the chain and contaminate current plant production batches. Located between the inside and outside sidebars, the barrier seals prevent a build-up of material due to “flooding” of the elevator boot section, which can result in dry cavitation of pins.
