SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and unique plates to realize a perfect engagement mechanism, and may continue to keep a noise degree remarkably reduced than traditional roller chains.
SC style silent chains is often utilized for large speed and big tension transmission much like a toothed metallic belt since the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging construction for more decreased noise level.
PS silent chain
A PS kind silent chain includes a structure by which a set of specially formed connecting pins and locker pins get in touch with each other when rotating at just about every versatile bearing place. So, it generates significantly less heat specially in large speed operation and it is exceptional in sturdiness. On top of that, the specially formed pins enormously lower shock when the chain is engaged with sprockets, offering a greater silencing effect than SC silent chains.
Sprockets for silent chains adopt exclusive modules in involute tooth varieties for the SCA 04××, SC 25××, SC 06×× to the former page and PS silent chains to make sure silent large velocity operation. For all sizes, the sprocket tooth heads usually are hardened by induction hardening or carburizing.
