Notes:
- Stiffness of bearing is rated in inches of deflection per pound of load.
- This data applies to standard cantilever bearings loaded at the mid-point of the unsupported half, at 0 degrees rotation.
- Torsional Spring rates: (in*lb/Degree) rates of standard C-Flex bearings generally fall within +/-10% of these values at zero load.
- Load Capacity: Lt or Lc (Pounds load in tension or compression) These values are maximum loading (weight or static force) at zero deflection. Load requirements, angular deflection and cyclic life must be considered when sizing bearings. Lc is pure radial load creating compressive stresses in the spring, while Lt is a pure radial load creating tensile stresses.

I-40AMA5 bearings have an indefinite life at ±1.3° of rotation and zero load. Life expectancy declines with increasing angles above ±1.3 ° and with increasing loads.
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. It can be used simply as an oscillating unit or an extremely sensitive critical element. The bearing itself consists of two sleeves held in position by three leaf springs on two planes. There is no contact between the sleeves, eliminating friction. The springs provide the pivotal action which is inherently self centering, requires no lubrication or maintenance and has zero backlash. The bearing is also available with an additional sleeve allowing for central mounting providing two pivotal arms (the double end bearing, sizes AD to JD).
