Comparison of c-type flexures with different bending radius

The flexure bearing is one of the key components of linear motor. Due to its frictionless, wearless, high radial and low axial stiffness; it is a very critical part of any linear actuator. The flexure bearing has increased the reliability and life of operation of linear actuators used in cryocoolers. This paper discusses the failure aspects of C-Type flexure with 3 mm bending radius in comparison with flexure bearing of different bending radii. Experimental results of 3 mm and 8 mm bending radii flexures are also discussed.
