A constant force spring is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant. This is true if the change in coil diameter due to buildup is disregarded. (read more)

Lee adds 40 Stock Constant Force Spring Designs tp 2008 Catalog offering. (read more)

This CNF Type Mount - automatically adjusts stiffness in response to load. AAC has introduced 3 new sizes of constant natural frequency mounts - (CNF Type). The natural frequency of a system by its definition is proportional to the square root of the ratio of its stiffness to its mass. (read more)

MW Industries custom manufactures constant force springs in strip widths of .187" to 2",in thicknesses of .003" to .031", and lengths of 12" to 60" in all standard end treatments. They are ideal for motor brush springs, counterbalances, timing mechanisms, cable retractors and retail product displays. (read more)

Conforce springs offer high force output with very small space requirements, provide long linear reach with minimal force buildup, and store power indefinitely when extended. They are ideal for a wide variety of applications where constant force is needed, including applications requiring smooth returning and retrieving, counterbalancing applications, and tensioning and loading applications....

ISO 9001:2000 Registered. Bazz Houston has special machines to produce constant force springs. These springs require sophisticated design engineering and we run computer software on each requirement to ensure the validity of your design. (read more)

Operates as constant-current or constant-voltage supply (with monitor outputs), a family of 720-W ac/dc power supplies is available in versions with fixed outputs from 3.3 to 48 Vdc or adjustable outputs from 0 to 5 Vdc or 0 to 50 Vdc. Features of the 1U-high PFC devices include soft-start, inhibit, Vout-OK, internal EMI filtering and RFI shielding, and optional n+1 and parallel operation. (read more)

Oil-Rite Corporation of Manitowoc, Wisconsin has designed a unique automatic shutoff feature for its Constant Level Lubricators. An automatic shutoff will hold the liquid supply in the reservoir while refilling. After the filler cap is screwed down tightly, the liquid will again resume normal functioning. (read more)

The Custom Pick Constant Flow Direct Steam Injection Heater is used wherever a constant flow of heated liquid at precisely controlled temperatures is required. (read more)

The constant-force spring is will suited to long extensions with no load build-up. In use, the spring is usually mounted with the ID tightly wrapped on a drum and the free end attached to the loading force, such as in a counterbalance application. (read more)
