I would like to announce a new product that should create a major shift in high torque friction hinges. The friction hinge will range from nominal 20 to 60 in-lbs balanced or unbalanced torque. Corrosion resistance and waterproof capabilities are also optional. Spring clutches and torsion spring for a pop open feature is available as a custom design. A feature that has been requested is the main focus of the design: no grease at all, yet 40,000+ cycle life is easily achieved. When there is no grease cross contamination is impossible .The image above shows a single hinge with a one way clutch, zero backlash clutch integrated into the center. A lower torque version is in the works to be released. also the same footprint can be used for a rotary viscous dampers. Contact us at www.mmtech.us to discuss your special application.
