UNIVERSAL ELASTIC COUPLINGS WITH PINS NORTHON universal elastic couplings are designed to absorb torsional knocks, vibrations and to compensate for any misalignment in the angular and parallel connection of two shafts rotating machines, guaranteeing at the same time the required transmission of the power. It is well-known that it is virtually impossible to get a perfect alignment between them, and even more impossible to maintain it over time due to vibration and thermal expansion to which the structures involved are subjected. NORTHON elastic universal couplings provide a solution to these problems, as they guarantee freedom of movement, total security of transmission and reliability of use. CONSTRUCTION FEATURES Elastic coupling series ‘PN’ - Half couplings steel C40 UNI 7845, hot-pressed or forged and normalized - Pins steel C40 UNI 7845,lathed and grinded for forced mounting - Rubber elements in oil-resistant synthetic rubber NBR 70 ShoreA with canvas insertions - Operating temperature from -30° a +120°C (On request be possible to have rubber elements with higher resistance) - Accurate machining by using CNC machines - Perfect dynamic balance Elastic coupling series ‘PNHP’ Same as the PN version, built with tempered alloy steels and high-strength elastic elements for the transmission of higher torques. STANDARD AND SPECIAL PRODUCTIONS We guarantee the solution for every need, thanks to the availability of a full range of couplings of all types and various sizes, and our industrial capacity to realize in a short time also particular couplings required by the customer.
