Non-rotating flexure bearings for cryocoolers and other devices

A system comprising:

• a device;
• a support structure;
• and
• a flexure bearing configured to connect the device to the support structure, the flexure bearing comprising:
• an outer hub and an inner hub, the hubs configured to be secured to the support structure and to the device;
• and
• multiple sets of flexure arms connecting the outer hub and the inner hub, each set of flexure arms including symmetric flexure arms;
• wherein each flexure arm comprises one or more circular openings.

A method comprising:

• displacing a device coupled to a flexure bearing, the flexure bearing comprising an outer hub and an inner hub, the hubs configured to be secured to the device and to a support structure;
• deforming flexure arms in the flexure bearing as a result of the displacement, the flexure bearing comprising multiple sets of flexure arms connecting the outer hub and the inner hub, each set of flexure arms including symmetric flexure arms and one or more circular openings;
• and
• substantially preventing rotation of the device during the displacement.
