Stainless Steel Loop-End Long-Leg Precision Torsion Spring
Featuring an asymmetric design with a loop end for hook mounting and a long straight leg for positioning, it delivers reliable torque transmission and precise return action within limited installation space for various rotary linkage mechanisms.
Precision cold-wound from SUS304 stainless steel wire as a single integral component, the compact coil body delivers stable and consistent torque output. The closed loop end enables easy pin mounting, hook attachment, or pivot installation for efficient force transmission, while the extra-long straight leg provides reliable positioning by resting against stops or fitting into locating slots and holes. The asymmetric end configuration combines positioning and torque transmission within one component, simplifying assembly while improving operational reliability. The stainless steel body offers natural corrosion resistance without additional surface treatment, making it suitable for long-term use in consumer electronics, industrial equipment, and automation mechanisms.
