SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to realize an excellent engagement mechanism, and will keep a noise level remarkably lower than typical roller chains.
SC type silent chains could be made use of for high speed and significant stress transmission similar to a toothed metallic belt because the plates immediately engage together with the sprockets for driving.
SCR-04 silent chains are created with inner engaging structure for more reduced noise level.
PS silent chain
A PS kind silent chain features a framework during which a set of specially formed connecting pins and locker pins make contact with each other although rotating at each versatile bearing place. As a result, it generates significantly less heat specially in large velocity operation and is outstanding in sturdiness. In addition, the specially formed pins significantly lower shock when the chain is engaged with sprockets, providing a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth types for your SCA 04××, 
SC 25××, SC 06×× over the earlier webpage 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.
