Spiral Springs

• $300.00

Spiral springs are used as balancing springs for smaller angles of rotation. The energy stored is used as a counterbalance or self-aligning torque. The increase in the spring curve is almost linear.
Spiral springs (also called clock springs or flat coil springs) are flat strips of metal wound in a spiral shape to store rotational energy. Unlike helical compression or extension springs, spiral springs work primarily in torsion—they provide torque when twisted. They are commonly made from high-carbon spring steel, stainless steel, or beryllium copper for durability, elasticity, and fatigue resistance. Spiral springs are widely used where a rotational force or tension over a long arc is needed in a compact space.
These springs are commonly found in clocks, timers, measuring instruments, seat belts, retractable tape measures, and electrical contacts. Their design allows for smooth, controlled release of energy over a full rotation or part of a rotation, making them ideal for precision devices and mechanisms that require consistent torque in limited spaces.
