FLEXI-HINGE

Cutaway view shows how crossed springs are situated within the two-part capsule.

MATERIAL: 400 Series Stainless Steel

OPERATING TEMPERATURE: -65°F to +350°F

APPLICATIONS: Optical Mounts, Belt Tensioners, Linear Positioners, Lever Actuators and Sensitive Measuring Instruments.

Flexi-Hinge is a compact, versatile, easy-to-install device which requires no maintenance, offers indefinite life and is resistant to detrimental environmental conditions. Highly accurate, even after a lifetime of cycling, Flexi-Hinges offer the optimum solution for many of today's engineering problems. The design utilizes crossed springs made to exacting tolerances of high-strength corrosion-resistant steel, capsuled in a cylindrical housing, to provide angular travel up to ± 30°. They are frictionless, require no lubrication, can function at limited angular travels indefinitely, are self- centering when unloaded, and have extremely low hysteresis. Lubrication migration and brinelling are eliminated. Flexi-Hinges perform their function without maintenance within a wide temperature range, extreme vibration, dust, abrasive slurry, and even a vacuum. MAXIMUM ANGULAR TRAVEL FOR INDEFINITE LIFE: Series 10: ± 15° Series 20: ± 7.5° Series 30: ± 3.7°

SPECIFICATIONS: Spring Rate Tolerance: ± 10% at Zero Load Mounting Hole: .0005 to .0010 Larger than Flexi-Hinge O.D.

LEVEL ACTUATORSAccurate motion requirements in areas of contamination, temperature extremes, or in a vacuum, can be easily provided through linkages utilizing Flexi-Hinge.

TENSIONERSBelt or chain tensioning can be easily achieved through the use of Flexi-Hinges. Tolerant of hostile environments and not subject to wear, extreme long life can be expected without maintenance.

RESTRAINED or DAMPENED OSCILLATING MOTIONEccentric or circular oscillating mechanisms can utilize Flexi-Hinge to provide centralizing and dampening actions for a lifetime of maintenance-free performance.

GAGES / SENSORSMiniature sizes which are free of error from backlash, friction or wear make Flexi-Hinges ideal for applications where positions must be accurately measured or outside forces sensed.

VIBRATING / SORTING MECHANISMSA workhorse, capable of supporting heavy loads for years of continuous service without wear or deterioration, Flexi-Hinges are ideal for equipment such as vibrating hoppers operating in severe environments.

LINEAR POSITIONERSFree of errors due to backlash, friction or wear, Flexi-Hinges mounted in suitable geometric structures can provide accurate linear movement or adjustment.

OPTICAL or MAGNETIC DISC READ / WRITE HEADSWith their constant, predictable spring rate, Flexi-Hinges are immune to the problems of starting vs. moving torque requirements of conventional bearings. Also, since they operate without backlash errors or wear, a lifetime of accurate performance can be expected.
