NO OUTSOURCING All products are designed and manufactured internally, in order to ensure the complete control of all processes and the best quality. Spacer and Floating Shaft Coupling must specify shaft separation or DBSE. Special manufacturing solutions can be proposed, like with spacers in fiberglass, electrically insulated and made of composite material, for extended spans. The full-flex gear couplings manufactured by MAINA S.p.A. are employed to mechanically connect two rotating shaft which have to transmit a torque, in a torsionally rigid way. This site or third-party tools used by the site, make use of cookies that are necessary for its functionality and useful for the purposes outlined in the cookie policy. MAINA produces rail couplings (SRMC type) for specific applications on trams, subways, regional trains and cargo trains, fast trains. This field is for validation purposes and should be left unchanged. For over sixty years MAINA has been manufacturing gear couplings of all types and dimensions: standard couplings type GO-A, with outer flange diameter up to 500 mm; large-size couplings type GO-B and GO-B.HT, with outer flamge diameter up to 2000 mm; MAINA has been manufacturing industrial universal shafts over the latest thirty year. (See other side for more details). Gear couplings can be made of different types of steel, as AISI 1045, AISI 4140, Nitralloy N/135/135M which are hardened and tempered before being machined.

Safety devices protect all items in a kinematic chain, allowing the line to work at a pre-setted maximum level. For over sixty years MAINA has been manufacturing gear couplings of all types and dimensions: standard couplings type GO-A, with outer flange diameter up to 500 mm; large-size couplings type GO-B and GO-B.HT, with outer flamge diameter up to 2000 mm; couplings for special applications type G20, G35 and G60, suitable for high misalignments, up …

Special manufacturing solutions can be proposed, like with spacers in fiberglass, electrically insulated and made of composite material, for extended spans. MAINA produces disc couplings for wind turbines (WGL type), offering high capacity of overload, excellent torsional stiffness and long life with no need of maintenance. MAINA can provide different safety devices to be incorporated between two flanges: Corso Alessandria 160, 14100 Asti (Italy) Phone +39 0141 492811 – Fax +39 0141 492860 P.IVA 06754430012 – Company information e-mail info@maina.it – www.maina.it Privacy Policy(function (w,d) {var loader = function () {var s = d.createElement("script"), tag = d.getElementsByTagName("script")[0]; s.src = "//cdn.iubenda.com/iubenda.js"; tag.parentNode.insertBefore(s,tag);}; if(w.addEventListener){w.addEventListener("load", loader, false);}else if(w.attachEvent){w.attachEvent("onload", loader);}else{w.onload = loader;}})(window, document); – Cookie Policy – Safety Policy. Gear Couplings. In the event of a catastrophic high torque, the device interrupt the torque flow in the driveline, limiting expensive damages and production shutdown. If you would like to know more or opt-out of all or some of the cookies, please refer to the cookie policy. These disc couplings are equipped with brake disc in alloy steel and with spacers in fiberglass, electrically insulated. The torque is transmitted from hub to sleeve and viceversa, by the working gear teeth and between the connecting flanges of the two hubs by calibrated bolts. Gear spindles are designed according to customer’s specifications and are mostly tailor made, creating the … Continued, For over sixty years MAINA has been manufacturing gear couplings of all types and dimensions: standard couplings type GO-A, with outer flange diameter up to 500 mm; large-size couplings type GO-B and GO-B.HT, with outer flamge diameter up to 2000 mm; couplings for special applications type G20, G35 and G60, suitable for high misalignments, up … Continued, Safety devices protect all items in a kinematic chain, allowing the line to work at a pre-setted maximum level.

These remarkable-dimension gear spindles, with fix or telescopic intermediate shaft, can transmit high torques, with working angles reaching up to 3°. MAINA produces standard series disc couplings (GL type), resistant to wear and not requiring lubrication and maintenance. They are long-life couplings, grease or oil lubricated, noiseless and able to absorb important axial movements, with misalignment capacity up to 6° and suitable for high rotation speed.
