Free-Flex(reg) Pivot frictionless, precision cross-spring bearing is for use wherever limited angular rotation bearings are required for angular travel up to ±30 degrees. The bearings require no lubrication or maintenance, are dirt insensitive, and eliminate the inaccuracies of friction, stiction, wear, radical clearances, and backlash. The pivot has a high radial and axial stiffness to maintain repeatability to ±0.000001 inch in one plane of motion, with low hysteresis, center shift, and thermal drift.
