SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize a great engagement mechanism, and can maintain a noise level remarkably decrease than standard roller chains.
SC variety silent chains is usually employed for large velocity and substantial tension transmission similar to a toothed metallic 
belt since the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for even more reduced noise degree.
PS silent chain
A PS type silent chain features a framework by which a set of specially formed connecting pins and locker pins speak to each and every other though rotating at each and every flexible bearing place. So, it generates less heat primarily in high pace operation and it is fantastic in sturdiness. Furthermore, the specially formed pins drastically lessen shock when the chain is engaged with sprockets, providing a larger silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× to the past webpage and PS silent chains to be sure silent substantial pace operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
