Free-Flex® Pivots

Custom Flexure Engineering

Riverhawk engineers custom flexures in virtually any configuration — for non-standard stiffness, range, materials, or environmental requirements.

Custom Flexure Engineering

Product Overview

When standard catalog pivot sizes and configurations don't meet your application requirements, Riverhawk's engineering team designs fully custom Free-Flex® flexures to your specifications. Custom pivots are available in configurations beyond cantilevered and double-ended — including linear flexures, compound pivot arrangements, and integrated structural assemblies.

Custom designs are available in a wide range of materials including steel, titanium, beryllium copper, and stainless steel. Material selection is driven by the stiffness requirement, angular range, operating environment, and fatigue life requirements.

Riverhawk engineers work directly with customers through the design process — providing stiffness calculations, range of motion analysis, fatigue life predictions, and dimensional drawings before manufacturing begins.

Key Features

  • Any Configuration — cantilevered, double ended, compound, linear
  • Non-Standard Stiffness — any spring rate achievable through geometry
  • Extended Angular Range via compound pivot arrangements
  • Material Options: Steel, Titanium, Beryllium Copper, Stainless Steel
  • Full engineering analysis: stiffness, fatigue life, range of motion
