SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve an ideal engagement mechanism, and might continue to keep a noise degree remarkably reduce than conventional roller chains.
SC type silent chains could be used for high pace and huge tension transmission just like a toothed metallic belt because the plates right engage using the sprockets for driving.
SCR-04 silent chains are created with inner engaging framework for additional lowered noise level.
PS silent chain
A PS variety silent chain has a construction in which a set of specially formed connecting pins and locker pins get in touch with each other although rotating at each versatile bearing position. Hence, it generates much less heat specially in large speed operation and is outstanding in sturdiness. Additionally, the specially formed pins greatly reduce shock once the chain is engaged with sprockets, delivering a greater silencing impact than SC silent chains.
Sprockets
Sprockets for silent chains adopt exclusive modules in involute tooth varieties to the SCA 04××, SC 25××, SC 06×× within the prior page and PS silent chains to make sure silent higher speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
