Constant Force Springs
Sai Springs offers a range of Constant Force Springs. Constant load springs are found in fire dampers and electric motors and are also used to counterbalance items, such as windows (known in the window industry as coil balance springs), doors, display racks and trays counterbalances, door closers, cable retractors, hose retrievers, tool head returns, cabinet and furniture components, gym equipment, hair dryers, toys, electric motors, appliances, space vehicles, and other long-motion functions. These springs can also be used as a return or retracting mechanism. A constant force spring provides a smooth, even, uniform load through its entire length or travel (deflection). Motor springs are used for cable retraction, power generation, etc. Power springs are used for retracting applications such as seat belt webbing, tape measures and dog leads, connectors, air conditioners, seat recliner, window regulator mechanisms, etc. Travel (extension, deflection) is limited only by the length of material in the spring. Load is a function of material width, thickness and coil diameter. This type of springs is manufactured by stainless steel raw material. This spring type derives its name from its ability to extend through its full working length while being maintained in any position by the same force. Constant load springs are available in a wide variety of sizes and the recent introduction of a purpose built plant ensures the price competitiveness of the smallest production run.
