Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to attain a perfect engagement mechanism, and will keep a noise degree remarkably reduced than standard roller chains.
SC kind silent chains is often utilized for higher pace and massive tension transmission much like a toothed metallic belt because the plates right engage using the sprockets for driving.
SCR-04 silent chains are made with inner engaging framework for more diminished noise level.
PS silent chain
A PS style silent chain has a framework in which a set of specially formed connecting pins and locker pins make contact with every other when rotating at every versatile bearing position. Consequently, it generates significantly less heat in particular in substantial speed operation and it is great in sturdiness. On top of that, the specially formed pins tremendously decrease shock once the chain is engaged with sprockets, giving a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× about the earlier web page and PS silent chains to make certain silent large speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
