This Huco Huco-Pol Acetal double universal joint has yokes, headed bore inserts, and cross pieces made of brass with a chromate and passivate finish for strength, durability, and resistance to corrosion. The hubs are black-oiled alloy steel for strength and corrosion resistance, and the Acetal body electrically isolates the shafts to prevent electrical arcing and circuit shortages. It has two points of flexion for additional capacity to accommodate misalignment, and can operate in temperatures ranging from -4 to 140 degrees F (-20 to 60 degrees C). This Huco Huco-Pol Acetal double universal joint is suitable for use in applications where misalignment results in low stress loads such as in electro-medical and laboratory equipment, business machines, and food processing systems, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Huco Dynatork manufactures couplings, piston air motors, brakes, clutches, gear boxes and other transmission products. The company, founded in 1965, meets the quality assurance standards of the British Standards Institution (BSI), the International Organization for Standardization (ISO) and the Deutsches Institut fr Normung (DIN), and is based in Hertfordshire, England.
