SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve a great engagement mechanism, and may retain a noise level remarkably reduced than conventional roller chains.
SC variety silent chains is often utilised for substantial velocity and huge stress transmission just like a toothed metallic belt since the plates directly engage using the sprockets for driving.
SCR-04 silent chains are made with inner engaging framework for additional reduced noise level.
PS silent chain
A PS form silent chain features a structure in which a set of specially formed connecting pins and locker pins get hold of each other whilst rotating at each and every flexible bearing place. Thus, it generates less heat especially in high pace operation and it is great in durability. Additionally, the specially formed pins drastically cut down shock when the chain is engaged with sprockets, providing a increased silencing impact than SC silent chains.
Sprockets for silent chains adopt exclusive modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× over the former page and PS silent chains to guarantee silent substantial speed operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
