Features & Advantages
Consistent rotational performance for dynamic mechanisms.
Advanced multi-axis CNC coiling ensures the exact free angle between legs is maintained across high-volume production runs.
Engineered with calculated inner diameters to prevent binding when the spring body reduces in size during rotational deflection.
Manufactured using premium grade wire and optimized coil pitches to eliminate destructive friction between adjacent coils.
Custom leg lengths and bend configurations available to secure perfectly onto your specific shafts or anchoring points.
Common Applications
Providing essential rotational return force across industries.
Hinges & Lids
Providing counterbalance and return force for doors, covers, and access panels.
Levers & Switches
Ensuring reliable rotational return in mechanical controls and electrical switchgear.
Clamping Tools
Standard gripping force applications in household and industrial clamping mechanisms.
Automotive Components
Used in seatbelt mechanisms, trunk latches, and transmission assemblies.
