SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish an excellent engagement mechanism, and might maintain a noise degree remarkably lower than standard roller chains.
SC form silent chains could be applied for higher pace and large stress transmission similar to a toothed metallic belt because the plates right engage together with the sprockets for driving.
SCR-04 silent chains are created with inner engaging framework for additional decreased noise level.
PS silent chain
A PS variety silent chain features a framework by which a set of specially formed connecting pins and locker pins 
get in touch with each and every other when rotating at each and every flexible bearing position. Consequently, it generates less heat specially in higher speed operation and it is excellent in durability. Furthermore, the specially formed pins greatly lower shock once the chain is engaged with sprockets, giving a greater silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× on the former web page and PS silent chains to be sure silent large speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
