SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to attain a perfect engagement mechanism, and might retain a noise degree remarkably reduced than conventional roller chains.
SC sort silent chains may be made use of for large pace 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 additional diminished noise level.
PS silent chain
A PS kind silent chain includes a construction during which a set of specially formed connecting pins and locker pins make contact with each and every other though rotating at each and every versatile bearing place. So, it generates significantly less heat particularly in substantial speed operation and is fantastic in durability. In addition, the specially formed pins considerably decrease shock when the chain is engaged with sprockets, providing a larger silencing impact than SC silent chains.
스프로킷
Sprockets for silent chains adopt special modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× on the prior web page and PS silent chains to make sure silent substantial velocity operation. For all sizes, the sprocket 
tooth heads are usually hardened by induction hardening or carburizing.
