SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and specific plates to attain a great engagement mechanism, and can keep a noise level remarkably reduce than traditional roller chains.
SC type silent chains is often utilized for large speed and huge stress transmission similar to a toothed metallic belt because the plates straight engage with the sprockets for driving.
SCR-04 silent chains are developed with inner engaging structure for additional diminished noise degree.
PS silent chain
A PS style silent chain features a structure through which a set of specially formed connecting pins and locker pins contact each other whilst rotating at each versatile bearing position. Consequently, it generates much less heat particularly in high pace operation and is excellent in durability. In addition, the specially formed pins significantly decrease shock when the chain is engaged with sprockets, delivering a greater silencing result than SC silent chains.
Sprockets for silent chains adopt distinctive modules in involute tooth forms for that SCA 04××, SC 25××, SC 06×× around the former page and PS silent chains to make certain silent higher speed operation. For all sizes, the sprocket tooth heads are usually hardened by induction hardening or carburizing.
