About Flat & Spiral Springs
Flat spiral springs are springs wound from flat strip (rather than round wire) into a spiral or specialised flat form, storing energy through bending of the strip. They deliver torque or force in a compact, flat package and are used where a rotational return, constant pull, or stacked-load characteristic is needed. The family spans several related flat-strip and disc forms: clock-type or power spiral springs (a flat strip coiled in a spiral that delivers torque as it unwinds, used in retractors, timers, and counterbalances); constant-force springs (a pre-stressed strip coiled tightly on a drum that gives near-constant force over long extension, used in counterbalances and cable retractors); spiral torsion springs (open spirals delivering torque over limited rotation); and disc/Belleville spring washers (coned discs to DIN 2093 that give high force in short deflection and can be stacked for tuned characteristics). Strip material is commonly high-carbon spring steel (e.g. C67S/C75S/CK75), stainless 301/302 or 17-7 PH for corrosion and fatigue resistance, and copper alloys where conductivity or non-magnetic behaviour is needed; Belleville washers also use alloy spring steel hardened and tempered. Finishes include phosphate, oxide, zinc, and passivation. Selection considers torque or force curve, rotation or deflection range, fatigue life, space, and environment. Through Himalay, partner manufacturers can typically supply strip material certificates to EN 10204 3.1 where specified, load/torque and dimensional inspection reports, hardness and coating data, and RoHS/REACH declarations; material, finish, and any test documentation are coordinated as part of the standard order flow.
