The Mechanical Power Transmission Association (MPTA) is an organization dedicated to promoting the manufacture and sale of Mechanical Power Transmission Equipment, while also increasing public awareness and knowledge of such equipment. They have developed industry standards, primers, and bulletins related to pulleys, sheaves, chains, and couplings, and offer a wide range of products through their member companies.
MPTA has three divisions focused on belt drive pulleys, couplings, and chain sprockets, and is known for its tradition of developing voluntary dimensional and application standards. They work in collaboration with ASME and ARPM to develop and harmonize standards, and offer various programs, meetings, and resources for their members. Additionally, MPTA provides a useful Statistics Program that allows participating members to confidentially share their sales figures on a monthly basis.
