The C-Flex bearing or pivot is a cylindrical, limited rotational bearing, with a high relative radial and axial stiffness which is available in low, medium, or high torsional spring rates. It is typically available for maximum deflection angles of +/-30°, but various configurations are supplied upon request. Torsional stiffness ranges from .0003 Lb-In/degree to 7.8023 Lb-In/degree. It can be used simply as an oscillating unit or an extremely sensitive critical element.
The advantages of cross-flexure bearings has been well documented in connection with the replacing of ball bearing pivots in optomechanical applications. One such application in which the C-Flex bearing has outperformed alternatives is the scanning mirror assembly of a mass spectometer. Here two mirrors are mounted on an assembly and laser beams are scanned across samples to be analyzed. The lubrication free, frictionless movement of the C-Flex bearings is ideal in applications such as this where the outgassing from bearing lubricants could contaminate the optics, and bearing wear due to continuous limited rotation would eventually result in movement errors.
Custom designs for heavy loads (>1600 lbs.), special materials (e.g., Hast X, Titanium, BeCu) or high volume/low cost can be provided.
