8 mm Shaft Ortho-Planar Flexure Spring
A one-piece ortho-planar flexure spring. Three folded 2 mm arms let the hub move along the axis while it stays parallel and centred. The 8.3 mm bore slides onto an 8 mm rod or shaft, and the 70 mm outer ring bolts down through three M3 clearance holes. Use it to preload a 608 bearing stack, push a sliding collar back, or replace a wave washer you don't have.
