SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and exclusive plates to accomplish a great engagement mechanism, and can preserve a noise level remarkably decrease than traditional roller chains.
SC form silent chains can be utilised for large velocity and 
significant stress transmission similar to a toothed metallic belt since the plates straight engage together with the sprockets for driving.
SCR-04 silent chains are designed with inner engaging structure for even further reduced noise degree.
PS silent chain
A PS kind silent chain features a structure during which a set of specially formed connecting pins and locker pins get hold of every single other while rotating at every single flexible bearing place. Thus, it generates less heat especially in higher pace operation and it is excellent in durability. Moreover, the specially formed pins considerably lessen shock when the chain is engaged with sprockets, supplying a increased silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt particular modules in involute tooth kinds for your SCA 04××, SC 25××, SC 06×× over the former webpage and PS silent chains to guarantee silent substantial pace operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
