SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish a perfect engagement mechanism, and may maintain a noise level remarkably reduce than conventional roller chains.
SC style silent chains can be applied for high velocity and big tension transmission much like a toothed metallic belt since the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging construction for more reduced noise degree.
PS silent chain
A PS sort silent chain has a construction during which a set of specially formed connecting pins and locker pins get in touch with every other while rotating at just about every flexible bearing place. Thus, it generates much less heat primarily in higher speed operation and is exceptional in durability. Moreover, the specially 
formed pins significantly lessen shock once the chain is engaged with sprockets, giving a greater silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× around the earlier webpage and PS silent chains to guarantee silent high speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
