Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to accomplish a perfect engagement mechanism, and can preserve a noise level remarkably reduce than standard roller chains.
SC form silent chains could be made use of for large pace and huge stress transmission much like a toothed metallic belt since the plates immediately engage together with the sprockets for driving.
SCR-04 silent chains are made with inner engaging construction for additional diminished noise degree.
PS silent chain
A PS style silent chain has a construction in which a set of specially formed connecting pins and locker pins make contact with each other whilst rotating at every single versatile bearing position. Hence, it generates significantly less heat specially in high pace operation and it is excellent in durability. Moreover, the specially formed pins significantly lessen shock once the chain is engaged with sprockets, providing a higher silencing impact than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× about the former page and PS silent chains to ensure silent substantial pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
