SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to accomplish a great engagement mechanism, and might maintain a noise level remarkably decrease than typical roller chains.
SC kind silent chains is often used for large speed and massive stress transmission much like a toothed metallic belt because the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are intended with inner engaging structure for even further reduced noise level.
PS silent chain
A PS type silent chain has a construction during which a set of specially formed connecting pins and locker pins contact each other whilst rotating at every single flexible bearing place. Therefore, it generates significantly less heat primarily in higher pace operation and is fantastic in sturdiness. On top of that, the specially formed pins considerably cut down shock once the chain is engaged with sprockets, offering a larger silencing effect than SC 
silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× to the former webpage and PS silent chains to ensure silent large speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
