It's a fact that drive systems wouldn't function properly or efficiently without couplings. They quietly go about their business of transferring motion from one drive element to the next. In the PT market today, couplings have the unique challenge of satisfying a variety of customer needs including tighter tolerances, higher speeds and a more versatile selection process.

In most cases, industrial power transmission calls for flexible rather than rigid couplings in order to forgive minor shaft misalignment. For that reason, this article will focus solely on the selection of flexible couplings.
