SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to attain an excellent engagement mechanism, and will keep a noise level remarkably lower than traditional roller chains.
SC style silent chains might be applied for high speed and large stress transmission much like a toothed metallic belt because the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging structure for additional diminished noise level.
PS silent chain
A PS kind silent chain features 
a construction during which a set of specially formed connecting pins and locker pins make contact with just about every other although rotating at each versatile bearing place. Hence, it generates significantly less heat in particular in large velocity operation and it is exceptional in sturdiness. Moreover, the specially formed pins greatly lessen shock when the chain is engaged with sprockets, supplying a larger silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth types for your SCA 04××, SC 25××, SC 06×× over the preceding web page and PS silent chains to make certain silent substantial velocity operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
