天水双节距滚子链条、润通机械、双节距滚子链条

输送用直边链板的双节距精密滚子链是在相应的传动链链号前面加一字头C表示。当采用大滚子时须在链号后面加一字尾L表示。当特意要区分链条所用滚子的大小时，则可对小滚子链条在链号后面加字尾S表示。

三排滚子链（Triplex  roller  chain）是滚子链条的一种类别，主要是三排短节矩精密滚子链组成，形成传动部件，用于传送机械动力链条，运用动能产地的原理，它由一系列短圆柱滚子链接在一起，由一个称为链轮的齿轮驱动。简单，可靠，高效

Three row roller chain (triplex roller chain is a kind of roller chain, mainly three rows of short moment precision roller chain, transmission parts, used for transmitting mechanical power chain, using the principle of kinetic energy origin, It is linked by a series of short cylindrical rollers, driven by a gear called a sprocket. Simple, reliable, and efficient
