SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to achieve an excellent engagement mechanism, and will retain a noise level remarkably lower than traditional roller chains.
SC kind silent chains could be utilised for higher pace and significant 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 structure for more reduced noise level.
PS silent chain
A PS form silent chain includes a construction by which a set of specially formed connecting pins and locker pins contact each other while rotating at every versatile bearing place. So, it generates much less heat especially in substantial speed operation and is superb in durability. In addition, the specially formed pins greatly lower shock when the chain is engaged 
with sprockets, supplying a higher silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth forms for your SCA 04××, SC 25××, SC 06×× about the prior page and PS silent chains to guarantee silent large speed operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
