SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to realize a great engagement mechanism, and can preserve a noise degree remarkably lower than traditional roller chains.
SC type silent chains might be made use of for high velocity and significant stress transmission just like a toothed metallic belt since the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are created with inner engaging construction for more lowered 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 contact every single other whilst rotating at every single flexible bearing position. Consequently, it generates significantly less heat in particular in higher speed operation and is superb in durability. On top of that, the specially formed pins enormously cut down shock once the chain is engaged with sprockets, providing a increased silencing effect than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth types for the SCA 04××, SC 25××, SC 06×× about the previous webpage and PS silent chains to make certain silent higher speed operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
