DOUBLE ENDED
FREE-FLEX PIVOTS

OVERVIEW

Double Ended Free-Flex® Pivots are another popular design of Riverhawk's flexures but can carry higher radial loads than single ended pivot bearings. Similar to the cantilevered design it was also possible to create an extensive standardized product line.

Double Ended Flexures are mounted with both ends attached which allows the center portion to rotate. The Double Ended pivots are used in applications such as seismometers, weigh stations, linkage systems, u-joints and many more. You can find out more about the different applications in the DATA & DOWNLOADS section.

Both ends fixed, center portion rotates
Supports suspended loads
Carries high radial loads

FEATURES

Free Flex Pivot Cantilevered-Double Ended Cutaway

Standard Materials

Riverhawk use AISI 410 corrosion-resistant steel for the body of the Pivot and AISI 420 for the flexures. This applies to the brazed construction.

Torsional Spring Rates

TSR are usually within ±10% or less of the values, which you can see in the table below. For spring rate values below 0.0018 in-lb/deg the tolerances can be much larger. Get in touch with our engineering staff if closer tolerances or actual values are required.

Tighter Diameter Tolerances

If a diameter tolerance of +0.0000/-0.0002 inches (or other variation) is required, please contact our engineering staff and specify “T2” after the catalog number.

Electron Beam Welded Pivots

are available for applications with high applied loads and low rotational angles.
