SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to realize an ideal engagement mechanism, and might hold a noise level remarkably lower than standard roller chains.
SC kind silent chains can be employed for large speed and big 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 framework for more diminished noise level.
PS silent chain
A PS sort silent chain has a structure in which a set of specially formed connecting pins and locker pins make contact with every other when rotating at each and every versatile bearing place. Consequently, it generates significantly less heat particularly 
in higher velocity operation and it is fantastic in durability. Furthermore, the specially formed pins drastically cut down shock once the chain is engaged with sprockets, delivering a higher silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt distinctive modules in involute tooth kinds for your SCA 04××, SC 25××, SC 06×× about the earlier web page and PS silent chains to make sure silent high speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
