SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to accomplish an ideal engagement mechanism, and can hold a noise level remarkably reduce than traditional roller chains.
SC variety silent chains is often used for high pace 
and massive stress transmission just like a toothed metallic belt because the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for even more diminished noise degree.
PS silent chain
A PS sort silent chain has a structure in which a set of specially formed connecting pins and locker pins get in touch with each other though rotating at each versatile bearing position. So, it generates less heat particularly in higher speed operation and it is superb in sturdiness. In addition, the specially formed pins tremendously reduce shock once the chain is engaged with sprockets, supplying a higher silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth types for your SCA 04××, SC 25××, SC 06×× on the past page and PS silent chains to be sure silent high speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
