Life Expectancy of C-Flex Pivot Bearings
The torsional spring rate and load capacity of C-Flex bearings is dependent upon length, width, and thickness of the internal flat spring beams. High angles of rotation require thin springs to reduce bending stress and thereby result in low torsional spring rates and correspondingly small load capacities.
The cycle life of C-Flex bearings is based upon the fatigue limit of the materials utilized for the spring beams. Bending and load stresses are considered in determining performance ratings which will statistically result in an infinite cycle life.
The flexure design is suitable for a variety of materials such as stainless steels of the martinistic or precipitation hardening variety: inconel, hastelloy, and beryllium copper among others.
