U.s. Tsubaki RS12BRB Roller Chain 3/4 in Pitch 12B Iso

Product Description

The U.S. TSUBAKI RS12BRB is a single-strand British Standard roller chain built to ISO specifications for demanding industrial and mechanical drive applications. It features a 3/4-inch pitch (0.7500 inches decimal) and a riveted connection type, delivering a rated load capacity of 7,500 pounds. The carbon steel construction provides the strength and wear resistance required in conveyor systems, power transmission drives, and machinery where consistent chain performance is critical. This chain is typically installed by millwrights, maintenance technicians, and industrial mechanics working on drive or conveyor systems.

This chain is suited for industrial power transmission and conveyor applications requiring British Standard (ISO 12B) single-strand roller chain. The 10-foot length makes it appropriate for direct replacement runs or custom-cut drive configurations. Its ISO 12B designation ensures dimensional compatibility with standard 12B sprockets used in industrial machinery across manufacturing, processing, and material handling environments.

Installation Notes

Installation should be performed by a qualified millwright or industrial maintenance technician. De-energize and lock out the drive system completely before removing or installing chain. Ensure the replacement chain length and pitch match the existing drive specifications before cutting or connecting. Use a proper chain breaker and connecting link tool rated for the chain size to avoid damage to side plates or pins during assembly.
