SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish a perfect engagement mechanism, and might hold a noise level remarkably decrease than typical roller chains.
SC sort silent chains is usually used for higher pace and significant tension transmission similar to a toothed metallic belt because the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for even more reduced noise degree.
PS silent chain
A PS style silent chain features a framework in which a set of specially formed connecting pins and locker pins contact every other whilst rotating at every single flexible bearing place. Hence, it generates much less heat specially in substantial speed operation and it is outstanding in sturdiness. Furthermore, the specially formed pins enormously lessen shock once the chain is engaged with sprockets, providing a larger silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× within the earlier web page and PS silent chains to make certain silent substantial speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or 
carburizing.
