SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and particular plates to achieve a perfect engagement mechanism, and can preserve a noise level remarkably reduce than traditional roller chains.
SC style silent chains may be employed for higher pace and large stress transmission much like a toothed metallic belt because the plates directly engage using the sprockets for driving.
SCR-04 silent chains are made with inner engaging framework for even more reduced noise level.
PS silent chain
A PS type silent chain has a structure through which a set of specially formed connecting pins and locker pins contact each other although rotating at each versatile bearing position. Thus, it generates less heat especially in higher speed operation and it is exceptional in durability. Furthermore, the specially formed pins tremendously decrease shock when the chain is engaged with sprockets, supplying a larger silencing effect than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× within the preceding webpage and PS silent chains to make certain silent substantial pace operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
