Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to realize a perfect engagement mechanism, and can keep a noise degree remarkably lower than conventional roller chains.
SC kind silent chains can be applied for substantial velocity and significant stress transmission much like a toothed metallic belt because the plates immediately engage using the sprockets for driving.
SCR-04 silent chains are made with inner engaging construction for even further diminished noise degree.
PS silent chain
A PS form silent chain has a construction by which a set of specially formed connecting pins and locker pins contact every single other when rotating at every versatile bearing place. Thus, it generates less heat in particular in substantial pace operation and is fantastic in durability. Moreover, the specially formed pins enormously decrease shock once the chain is engaged with sprockets, supplying a larger silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for that SCA 04××, SC 25××, SC 06×× around the former page and PS silent chains to guarantee silent high speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
