SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to realize a great engagement mechanism, and can keep a noise degree remarkably reduced than standard roller chains.
SC form silent chains is often made use of for large pace and massive stress transmission much like a toothed metallic belt because the plates directly engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging framework for further reduced noise level.
PS silent chain
A PS variety silent chain features a construction through which a set of specially formed connecting pins and locker pins contact each other when rotating at every flexible bearing place. Hence, it generates much less heat in particular in large speed operation and it is excellent in durability. In addition, the specially formed pins considerably cut down shock once the chain is engaged with sprockets, giving a larger silencing result than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth varieties for your SCA 04××, SC 25××, SC 06×× about the earlier webpage and PS silent chains to make certain silent substantial pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
