Stainless Steel High-Turn Multi-Coil Precision Torsion Spring
Stores exceptionally high torsional energy within a compact footprint through its ultra-high-turn closely wound structure, delivering powerful and durably stable angular return force for precision rotational mechanisms.
Precision cold-wound from SUS304 stainless steel wire, the greatly increased coil count (typically 7+ turns) multiplies torsional energy storage within a similar outer diameter, far exceeding standard 2-3 turn torsion springs of the same size. This design enables the spring to deliver a near-constant torque output across a wide angular deflection range, ideal for precision mechanisms requiring stable return force throughout large rotation angles. The minimal short-leg ends reduce the overall assembly footprint for extremely space-constrained precision embedded applications. Two size variants cover different torque levels and installation space requirements.
Ultra-high coil count (7+ turns) wound structure stores 3-4x the torsional energy per unit volume vs. standard springs.
Near-constant torque output over a wide angular deflection range for smoother and more even return force.
Minimal short-leg design keeps overall height compact for precision embedded installation spaces.
SUS304 stainless steel body with natural corrosion resistance and clean finish — no coating needed.
Two size variants in the same series covering different torque levels and installation spaces.
Wire diameter, outer diameter, coil count, and arm length fully customizable per drawings.
Application areas: Precision instrument knob and adjustment mechanisms / Medical device precision hinges / Camera shutter and aperture return springs / High-precision valve rotational control / Consumer electronics precision pivot shafts
