SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to achieve a great engagement mechanism, and might maintain a noise degree remarkably decrease than typical roller chains.
SC form silent chains could be utilised for large pace and massive tension transmission just like a toothed metallic belt since the plates right engage with the sprockets for driving.
SCR-04 silent chains are designed with inner engaging construction for more lowered noise level.
PS silent chain
A PS style silent chain has a structure during which a set of specially formed connecting pins and locker pins get 
in touch with each and every other when rotating at every flexible bearing place. As a result, it generates less heat specially in high speed operation and it is great in sturdiness. In addition, the specially formed pins enormously lessen shock once the chain is engaged with sprockets, supplying a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth types for that SCA 04××, SC 25××, SC 06×× within the former web page and PS silent chains to be sure silent substantial velocity operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
