SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish a great engagement mechanism, and will keep a noise degree remarkably decrease than traditional roller chains.
SC variety silent chains can be utilized for higher speed and huge stress transmission much like a toothed metallic belt because the plates directly engage together with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging construction for even further diminished noise level.
PS silent chain
A PS type silent chain has a construction by which a set of specially formed connecting pins and locker pins make contact with just about every other though rotating at every flexible bearing position. So, it generates 
much less heat especially in higher speed operation and is exceptional in sturdiness. In addition, the specially formed pins greatly reduce shock when the chain is engaged with sprockets, providing a higher silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for your SCA 04××, SC 25××, SC 06×× over the preceding webpage and PS silent chains to ensure silent high velocity operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
