SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to achieve a great engagement mechanism, and will preserve a noise degree remarkably reduced than traditional roller chains.
SC form silent chains can be employed for large velocity and significant stress transmission much like a toothed metallic belt because the plates directly engage using the sprockets for driving.
SCR-04 silent chains are intended with inner engaging construction for more reduced noise level.
PS silent chain
A PS kind silent chain has a structure in which a set of specially formed connecting pins and locker pins get hold of each other even though rotating at just about every versatile bearing position. Therefore, it generates less heat especially in large velocity operation and it is outstanding in durability. Furthermore, the specially formed pins drastically reduce shock when the chain is engaged with sprockets, offering a larger silencing effect than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× around the past webpage and PS silent chains to make sure silent substantial speed operation. For all sizes, the sprocket tooth heads tend to be hardened by induction hardening or carburizing.
