英語 から 日本語 技術/工学 機械工学 chains

Another item from the list in a chain specification document, so no more context. Again, even though I know what sort of chain it is, I can't find a Japanese translation. The chain in question can be found here: http://www.hpionline.com/chainproducts/PassingLinkChain.htm

Any help will be (as always) greatly appreciated.
