SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates 
to accomplish a perfect engagement mechanism, and will maintain a noise level remarkably lower than conventional roller chains.
SC variety silent chains is usually utilized for high speed and massive stress transmission just like a toothed metallic belt since the plates right engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for additional diminished noise level.
PS silent chain
A PS type silent chain includes a structure during which a set of specially formed connecting pins and locker pins speak to just about every other although rotating at every single versatile bearing place. Thus, it generates less heat primarily in higher velocity operation and it is superb in sturdiness. On top of that, the specially formed pins significantly cut down shock once the chain is engaged with sprockets, supplying a higher silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× on the prior web page and PS silent chains to ensure silent higher speed operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
