SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and distinctive plates to achieve an excellent engagement mechanism, and can preserve a noise degree remarkably decrease than typical roller chains.
SC type silent chains might be utilized for substantial speed and substantial stress transmission just like a toothed metallic belt since the plates directly engage together with the sprockets for driving.
SCR-04 silent chains are intended with inner engaging framework for even more lowered noise level.
PS silent chain
A PS kind silent chain features a structure during which a set of specially formed connecting pins and locker pins get in touch with each and every other even though rotating at every single versatile bearing position. As a result, it generates less heat primarily in substantial pace operation and it is great in sturdiness. On top of that, the specially formed pins greatly lower shock once the chain is engaged with sprockets, offering a higher silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt unique modules in involute tooth types to the SCA 04××, SC 25××, SC 06×× within the past web page and PS silent chains to make certain silent substantial velocity operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
