Silent Chain

SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve a perfect engagement mechanism, and might hold a noise level remarkably decrease than conventional roller chains.
SC type silent chains is often employed for higher velocity and huge tension transmission similar to a toothed metallic belt because the plates straight engage with all the sprockets for driving.
SCR-04 silent chains are created with inner engaging structure for even more reduced noise level.
PS silent chain
A PS variety silent chain has a construction by which a set of specially formed connecting pins and locker pins get in touch with just about every other although rotating at each and every flexible bearing place. Consequently, it generates less heat specially in high velocity operation and it is excellent in durability. Additionally, the specially formed pins greatly cut down shock when the chain is engaged with sprockets, offering a greater silencing result than SC silent chains.
Sprockets
Sprockets for silent chains adopt special modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× on the prior page and PS silent chains to be sure silent substantial velocity operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
