SC silent chains (SCA, SCR, SC)
SC silent chains use specially-coated round pins and special plates to attain a perfect engagement mechanism, and will maintain a noise degree remarkably reduced than standard roller chains.
SC form silent chains can be utilized for large pace and massive tension transmission just like a toothed metallic belt because the plates immediately engage with the sprockets for driving.
SCR-04 silent chains are made with inner engaging framework for even further lowered noise level.
PS silent chain
A PS sort silent chain features a construction during which a set of specially formed connecting pins and locker pins get hold of each other whilst rotating at just about every flexible bearing position. Hence, it generates much less heat specially in higher velocity operation and is fantastic in sturdiness. Moreover, the specially formed pins tremendously lower shock when the chain is engaged with sprockets, offering a larger silencing impact than SC silent chains.
Sprockets for silent chains adopt unique modules in involute tooth kinds for the SCA 04××, SC 25××, SC 06×× on the preceding webpage and PS silent chains to guarantee silent higher velocity operation. For all sizes, the sprocket tooth heads are generally hardened by induction hardening or carburizing.
