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 degree remarkably reduced than standard roller chains.
SC style silent chains could be used 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 reduced noise degree.
PS silent chain
A PS type silent chain has a construction in which a set of specially formed connecting pins and locker pins make contact with every other whilst rotating at just about every versatile bearing place. Hence, it generates significantly less heat in particular in high pace operation and is excellent in durability. Moreover, the specially formed pins tremendously lessen shock when the chain is engaged with sprockets, providing a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× about the former web page and PS silent chains to make sure silent high pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
