Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to accomplish an excellent engagement mechanism, and can continue to keep a noise degree remarkably lower than standard roller chains.
SC style silent chains is usually applied for higher velocity and huge stress transmission similar to a toothed metallic belt because the plates right engage with all the sprockets for driving.
SCR-04 silent chains are intended with inner engaging structure for even further diminished noise degree.
PS silent chain
A PS type silent chain has a construction through which a set of specially formed connecting pins and locker pins get in touch with each and every other although rotating at every single versatile bearing position. Hence, it generates much less heat specially in substantial velocity operation and is exceptional in sturdiness. Moreover, the specially formed pins considerably lessen shock when the chain is engaged with sprockets, providing a higher silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× to the former web page and PS silent chains to be sure silent substantial speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
