SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to realize an excellent engagement mechanism, and will maintain a noise level remarkably reduce than typical roller chains.
SC variety silent chains can be employed for high speed and massive stress transmission much like a toothed metallic belt since the plates directly engage with the sprockets for driving.
SCR-04 silent chains are built with inner engaging structure for even further lowered noise degree.
PS silent chain
A PS sort silent chain includes a construction through which a set of specially formed connecting pins and locker pins contact each other though rotating at every versatile bearing place. Therefore, it generates less heat primarily in higher speed operation and it is superb in durability. Furthermore, the specially formed pins greatly lower shock once the chain is engaged with sprockets, providing a larger silencing result than SC silent chains.
Sprockets for silent chains adopt special modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× to the past page and PS silent chains to ensure silent high velocity operation. For all sizes, the sprocket tooth heads are often hardened by induction hardening or carburizing.
