Duplex Silent Chain

Duplex chains are designed to engage and drive sprockets from both sides of the chain. Ramsey manufactures three different styles of duplex silent chain; each has unique features and advantages:

Rampower duplex silent chain

Rampower Duplex

Rampower duplex, also known as RP duplex, provides approximately two times the power capacity of standard SC duplex chain. RP duplex is often well suited for new or replacement applications where power or speed requirements exceed the capability of SC duplex chain.

 

SC duplex silent chain

SC Duplex

SC duplex chains have been around the longest, are used primarily in replacement applications, and are often the most economical. SC duplex offers the advantage of reduced weight, but with a lower power capacity.

 

Ramflex silent chain

Ramflex

Ramflex is Ramsey’s most robust duplex chain design; it is particularly well suited to applications where shock or very high loads are encountered, or where space is limited. Ramflex directly interchanges with chain produced by some European manufacturers.
