SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to achieve a great engagement mechanism, and can continue to keep a noise level remarkably reduce than standard roller chains.
SC kind silent chains is often utilized for substantial pace and huge tension transmission much like a toothed metallic belt since the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are intended with inner engaging construction for more reduced noise degree.
PS silent chain
A PS sort silent chain includes a structure by which a set of specially formed connecting pins and locker pins contact every other while rotating at each versatile bearing position. Hence, it generates less heat specially in large speed operation and is fantastic in durability. On top of that, the specially formed pins greatly decrease shock once the chain is engaged with sprockets, giving a increased silencing effect than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× on the earlier webpage and PS silent chains to make sure silent high velocity operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
