SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to realize an ideal engagement mechanism, and might retain a noise level remarkably lower than traditional roller chains.
SC style silent chains might be employed for substantial speed and big stress transmission much like a toothed metallic belt because the plates immediately engage with all the sprockets for driving.
SCR-04 silent chains are designed with inner engaging construction for even further lowered noise level.
PS silent chain
A PS type silent chain features a framework by which a set of specially formed connecting pins and locker pins contact each other although rotating at every single versatile bearing position. Thus, it generates less heat in particular in large speed operation and is fantastic in durability. Moreover, the specially formed pins drastically minimize shock once the chain is engaged with sprockets, providing a higher silencing effect than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth kinds for that SCA 04××, SC 25××, SC 06×× over the earlier webpage and PS silent chains to be sure silent high speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
