SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to attain an excellent engagement mechanism, and may retain a noise degree remarkably reduced than typical roller chains.
SC type silent chains could be applied for large velocity and big tension transmission similar to a toothed metallic belt because the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for even further decreased noise degree.
PS silent chain
A PS variety silent chain features a construction in which a set of specially formed connecting pins and locker pins get in touch with every other though rotating at every flexible bearing place. As a result, it generates much less heat specifically in substantial speed operation and is great in durability. In addition, the specially formed pins enormously minimize shock once the chain is engaged with sprockets, delivering a larger silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt specific modules in involute tooth forms for the SCA 04××, SC 25××, SC 06×× about the past page and PS silent chains to be sure silent substantial pace operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
