SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to attain a perfect engagement mechanism, and will continue to keep a noise level remarkably reduce than conventional roller chains.
SC form silent chains is usually utilised for large speed and big tension transmission similar to a toothed metallic belt because the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are made with inner engaging construction for additional decreased noise degree.
PS silent chain
A PS sort silent chain has a construction during which a set of specially formed connecting pins and locker pins speak to each and every other though rotating at each and every flexible bearing place. Consequently, it generates much less heat primarily in large pace operation and it is fantastic in sturdiness. Additionally, the specially formed pins tremendously reduce shock once the chain is engaged with sprockets, providing a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth kinds for your SCA 04××, SC 25××, SC 06×× within the former webpage and PS silent chains to be sure silent large 
velocity operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
