Racetech Mil-Spec Gimbal Shaft 12.7mm x 12.7mm

The Racetech Mil-Spec Helico universal joint is designed to transmit rotational motion between two shafts with angular misalignment while maintaining excellent operational precision. Manufactured to a military specification (Mil-Spec), it meets high standards for quality, resistance, and reliability, making it an ideal solution for the most demanding racing applications.

This model is manufactured in accordance with MIL-J-6193, a specification originally developed for the aerospace and military sectors. Its Pin & Block design (shaft and friction pads) ensures smooth motion transmission with minimal play, while offering excellent resistance to mechanical stress and a long service life.

Machined from AISI 4142 chrome-molybdenum alloy steel with a cadmium-plated finish, this Helico universal joint offers excellent abrasion resistance and corrosion resistance. Its maximum operating angle of 30° compensates for misalignment while ensuring precise and consistent power transmission.

Renowned in the world of motorsports, Helico Racetech universal joints are used in mechanical controls, gearshift linkages, and other systems requiring reliable, precise, and durable power transmission.
