Sedis DELTA 20B-1 Spring Clip Steel Roller Chain Link 31.75mm Pitch 19.56mm Width Between Plates 17TD7000206

Sedis 17TD7000206 Spring Clip Steel Roller Chain Link 20B-1 is designed for demanding Mechanical Power Transmission systems requiring high strength and durability. Constructed from robust steel, the chain link features a spring clip mechanical link type ensuring reliable and secure connection in chain assemblies.

This roller chain link features a pitch of 31.75mm and a roller diameter of 19.05mm, accompanied by a width between roller link plates of 19.56mm, optimizing chain fit and function. It complies with internationally recognized standards DIN 8187 and BS 228, ensuring interchangeability with chains made to these specifications.

The DELTA series construction includes shot peened plates, preformed bi-conic bushes, and solid rollers, which enhance the chain’s fatigue resistance and wear characteristics. The chain links are pre-tensioned at 30 to 45 percent of their breaking load to maintain optimal performance under high power transmission conditions.

Pre-lubrication with technical wax increases the chain’s service life by reducing initial wear and friction. These features make this roller chain link suitable for industrial environments including manufacturing, construction, material handling, and other heavy-duty applications demanding reliable power transmission components.
