SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to attain a great engagement mechanism, and may hold a noise level remarkably lower than standard roller chains.
SC style silent chains can be used for higher pace and massive tension transmission similar to a toothed metallic belt since the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging construction for even more decreased noise level.
PS silent chain
A PS form silent chain features a structure during which a set of specially formed connecting pins and locker pins contact 
each other even though rotating at every single versatile bearing place. So, it generates much less heat primarily in higher velocity operation and is exceptional in durability. Additionally, the specially formed pins tremendously cut down shock once the chain is engaged with sprockets, delivering a increased silencing result than SC silent chains.

Sprockets for silent chains adopt special modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× to the past webpage and PS silent chains to make certain silent higher velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
