Spring winding services fabricate springs according to customer specifications. They use winding machines or winders to pull a wire and coil it into a spring shape. Spring winding services also use grinders and wheels, finishing equipment such as ovens and passivating tanks, hand tools, testing equipment, and tooling stock

Torsion springs are designed and wound to be activated rotationally, and to provide an angular return force

Compression springs are wound or constructed to oppose spring compression along the axis of wind

Extension springs are designed to oppose spring extension and/or provide return force to devices with extended positions

Preload springs, spacers and washers are used to provide end-play take up or a constant preload for bearings, gears and other mechanical components and assemblies

Die springs are helical compression springs that are made from rectangular wire. For the same deflection, they can carry roughly 30% more load than compression springs that use round wire

Power springs and spring motors are rotational-drive springs that are wound tightly and mounted on an arbor. They are used in applications such as retractable reels, tape measures, and retracting seat belts

Constant force springs are tightly coiled wound bands of pre-hardened spring steel or stainless steel strip. When extended, a constant force is exerted and maintained as the spring is allowed to close

Air springs use a contained column of air inside an elastomeric bellows or sleeve to buffer cyclic motion, provide vibration isolation, or serve as a pneumatic actuator

Specialty or proprietary products and accessories related to springs

Wave washers or wave springs are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock

Flat springs are flat strips of material that, when deflected by an external load, store and release energy

Web winders, rewinders and unwinders are used for winding, rewinding, and unwinding webs made of paper, film, foil, nonwovens and textiles.

Mechanical seals including mechanical face seals, bellows, gas seals, and cartridge seals.

Shims and shim stock are products used to fill in a space between two mating surfaces or components.
