MAINA has been manufacturing gear spindles for over forty years, supplying high-quality solutions for steel and metal rolling mills.
These remarkably-sized gear spindles, with fixed or telescopic intermediate shaft, are able to transmit high torques, with working angles of up to 3°.
The gear spindles are designed according to customer’s specifications and are mostly tailor made, creating the best product to suit their needs. MAINA can supply a variety of technologies for critical components, such as nitriding and case hardening and tempering, with final grinding of the working teeth.
To meet the demand for increased production and higher quality of the final products, with higher torques, speeds and misalignment angles in smaller spaces, MAINA has spent the last 15 years carrying out studies that have resulted in the creation of a new transmission, the HISPINDLE ® . Based on H11 technology, its increased performance is over 60% higher than that of the carburized transmission, solving problems in many sites all over the world.
