SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to attain an excellent engagement mechanism, and will preserve a noise level remarkably reduced than standard roller chains.
SC kind silent chains might be applied for higher pace and big tension transmission similar to a toothed metallic belt because the plates directly engage with all the sprockets for driving.
SCR-04 silent chains are designed with inner engaging construction for further decreased noise degree.
PS silent chain
A PS sort silent chain features a structure during which a set of specially formed connecting pins and locker pins make contact with each other when rotating at just about every flexible bearing place. Therefore, it generates much less heat specially in substantial velocity operation and is exceptional in durability. On top of that, the specially formed pins greatly lower shock once the chain is engaged with sprockets, supplying a greater silencing effect than SC silent chains.
Sprockets for silent chains adopt exclusive modules in involute tooth kinds to the SCA 04××, SC 25××, SC 06×× to the past web page and PS silent chains to make sure silent higher speed operation. For all sizes, the sprocket tooth heads are frequently hardened by induction hardening or carburizing.
