SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to accomplish a great engagement mechanism, and might continue to keep a noise level remarkably reduce than traditional roller chains.
SC sort silent chains may be applied for high speed and substantial tension transmission similar to a toothed metallic belt since the plates straight engage together with the sprockets for driving.
SCR-04 silent chains are created with inner engaging framework for more diminished noise degree.
PS silent chain
A PS kind silent chain includes a structure in which a set of specially formed connecting pins and locker pins get hold of every other even though rotating at just about every flexible bearing place. Therefore, it generates much less heat specially in high speed operation and it 
is excellent in durability. In addition, the specially formed pins significantly lower shock once the chain is engaged with sprockets, giving a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth kinds for that SCA 04××, SC 25××, SC 06×× within the preceding web page and PS silent chains to guarantee silent substantial speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
