SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to accomplish an excellent engagement mechanism, and will keep a noise level remarkably reduced than conventional roller chains.
SC sort silent chains might be employed for large velocity and large tension transmission much like a toothed metallic belt because the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for additional decreased noise degree.
PS silent chain
A PS style silent chain features a structure in which a set of specially formed connecting pins and locker pins contact each other whilst rotating at just about every versatile bearing place. As a result, it generates less heat in particular in high speed operation and is excellent in sturdiness. Furthermore, the specially formed pins considerably minimize shock when the chain is engaged with sprockets, providing a greater silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× around the prior page and PS silent chains to be 
sure silent higher velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
