To draw a spiral flexure bearing curve in SolidWorks:

Create a new part document.
Start a sketch on the desired plane.
Draw a centerline representing the axis of the spiral.
Create the profile of the spiral flexure bearing.
Use the "Sweep" feature, selecting the centerline as the path.
Adjust options for twist control, start and end conditions, and guide curves.
Apply the sweep feature to generate the spiral flexure bearing.
