SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize a perfect engagement mechanism, and may hold a noise degree remarkably reduce than standard roller chains.
SC form silent chains might be utilised for higher velocity and huge tension transmission just like a toothed metallic belt because the plates straight engage together with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging construction for even more diminished noise degree.
PS silent chain
A PS variety silent chain features a construction through which a set of specially formed connecting pins and locker pins contact every other though rotating at every versatile bearing position. As a result, it generates significantly less heat specially in large pace operation and it is great in durability. On top of that, the specially formed pins greatly decrease shock when the chain is engaged with sprockets, supplying a larger silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth forms for your SCA 04××, SC 25××, SC 06×× to the earlier webpage and PS silent chains to make sure silent substantial speed operation. For all sizes, the sprocket tooth heads are generally hardened 
by induction hardening or carburizing.
