Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to realize an excellent engagement mechanism, and might keep a noise degree remarkably decrease than conventional roller chains.
SC type silent chains may be utilised for substantial speed and large tension transmission similar to a toothed metallic belt because the plates directly engage with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging framework for additional decreased noise level.
PS silent chain
A PS style silent chain includes a framework during which a set of specially formed connecting pins and locker pins get hold of each and every other when rotating at just about every flexible bearing place. As a result, it generates significantly less heat in particular in substantial pace operation and is great in durability. Moreover, the specially formed pins enormously lessen shock when the chain is engaged with sprockets, giving a larger silencing result than SC silent chains.
Sprockets for silent chains adopt special modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× about the preceding page and PS silent chains to make sure silent large speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
