SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to attain an ideal engagement mechanism, and might preserve a noise degree remarkably reduced than typical roller chains.
SC style silent chains is often used for higher pace and substantial stress transmission just like a toothed metallic belt since the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are built with inner engaging construction for even more reduced noise level.
PS silent chain
A PS type silent chain features a construction during which a set of specially formed connecting pins and locker pins make contact with every single other although rotating at every flexible bearing place. Hence, it generates less heat specifically in large pace operation and is fantastic in durability. Furthermore, the specially formed pins considerably lower shock when the chain is engaged with sprockets, giving a larger silencing impact than SC silent chains.
Sprockets for silent chains adopt exclusive modules in involute tooth varieties to the SCA 04××, SC 25××, SC 06×× about the earlier page and PS silent chains to be sure silent high speed operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
