U.s. Tsubaki RS12BSSCL Connecting Link 3/4 in Pitch Iso 12B

Product Description

The U.S. TSUBAKI RS12BSSCL is a stainless steel connecting link designed for British Standard single strand roller chain with a 3/4 inch pitch (ISO 12B). It serves as the mechanical closure point that joins two ends of a chain run, allowing technicians to assemble or disconnect a chain loop without removing the entire drive assembly. The stainless steel construction resists corrosion, making this link suitable for wet, washdown, or chemically exposed environments. The pin diameter measures 0.475 inches, ensuring a precise fit within the 12B chain profile. Industrial maintenance technicians and mechanical contractors install this type of hardware during conveyor, drive, or power transmission servicing.

This connecting link is used on machinery and equipment that runs ISO 12B British Standard single strand roller chain at 3/4 inch pitch. Typical applications include conveyor drives, packaging equipment, agricultural machinery, and light industrial power transmission systems where chain replacement or periodic disconnection is part of a maintenance routine. Stainless steel construction extends service life in environments where carbon steel hardware would corrode prematurely, such as food processing, marine, or chemical handling installations.

Installation Notes

Installation of this connecting link is performed by qualified industrial maintenance technicians or mechanical contractors. De-energize and lock out all power to the drive system before working on any chain assembly, following applicable LOTO (lockout/tagout) procedures. Use appropriate chain tools to seat the connecting link clip or cotter pin fully and verify secure retention before returning the drive to service. Never operate chain drives with an improperly seated connecting link.
