SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to achieve an excellent engagement mechanism, and will keep a noise level remarkably reduced than typical roller chains.
SC form silent chains could be used for higher pace and significant stress transmission similar to a toothed metallic belt because the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging framework for even further reduced noise level.
PS silent chain
A PS variety silent chain has a construction by which a set of specially formed connecting pins and locker pins get in touch with each and every other when rotating at each flexible bearing position. Hence, it generates significantly less heat in particular in higher pace operation and is outstanding in sturdiness. Additionally, the specially formed pins tremendously reduce shock when the chain is engaged with sprockets, supplying a higher silencing effect than SC silent chains.
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× about the former webpage and PS silent chains to ensure silent high speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
