SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to attain an ideal engagement mechanism, and might retain a noise level remarkably decrease than typical roller chains.
SC type silent chains is usually employed for large pace and massive stress transmission just like a toothed metallic belt since the plates straight engage together with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging structure for more lowered noise degree.
PS silent chain
A PS variety silent chain includes a structure in which a set of specially formed 
connecting pins and locker pins get hold of each and every other even though rotating at just about every flexible bearing place. Consequently, it generates significantly less heat specifically in large speed operation and is great in sturdiness. Furthermore, the specially formed pins drastically reduce shock once the chain is engaged with sprockets, providing a greater silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× over the preceding page and PS silent chains to be sure silent substantial speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
