Flexural
Pivots
The original Free-Flex® Pivot bearing — frictionless, stiction-free, and lubrication-free. Trusted in over 4 million aerospace, military, semiconductor, and scientific applications for over 60 years.
What is a Free-Flex® Pivot?
Riverhawk's Free-Flex® Pivot is a frictionless, stiction-free flexure uniquely suited for limited angular travel applications of up to 60 degrees (±30 degrees) rotation. Our flexures are ideal for applications permitting no lubrication, demanding precise positioning, and requiring infinite cycle life.
For many applications the Free-Flex® Pivot is a superior alternative to roller element bearings, knife edge bearings, jeweled bearings, and other devices — offering zero friction, zero wear, and zero contamination.
Free-Flex® Pivot Benefits
Frictionless
Leaf spring technology eliminates moving parts and contact surfaces. No stiction, no breakaway torque — ideal for precision positioning.
No Lubrication Required
No sliding surfaces means no lubricants needed — perfect for vacuum, clean room, cryogenic, and high-temperature environments.
Infinite Cycle Life
Elastic flexure operation means no wear. No contact surfaces means no particle generation, critical for clean-room and space applications.
Exceptional Repeatability
Highly predictable and repeatable angular motion with low hysteresis — essential for calibration systems and scientific instrumentation.
