SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to accomplish an ideal engagement mechanism, and may keep a noise degree remarkably reduced than traditional roller chains.
SC variety silent chains is often employed for higher pace and large stress transmission just like a toothed 
metallic belt because the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are made with inner engaging structure for more reduced noise degree.
PS silent chain
A PS form silent chain features a framework through which a set of specially formed connecting pins and locker pins make contact with just about every other while rotating at every single versatile bearing position. Therefore, it generates significantly less heat especially in higher pace operation and is exceptional in durability. In addition, the specially formed pins enormously lower shock once the chain is engaged with sprockets, offering a increased silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× around the prior web page and PS silent chains to make certain silent substantial speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
