Expanded spring range adds to design
options
Constant-force springs exert a near constant restraining force to resist uncoiling, and wave springs save space in compression spring applications.
Lee Spring has added new constant-force and wave springs to its portfolio, increasing its stock spring range to more than 15,500 different types The new springs will be launched in the UK at the Southern Manufacturing Exhibition in February 2008, and custom designs will also be offered

Manufactured from high-yield 301 stainless-steel strip Lee Spring's constant-force springs exert a near constant restraining force to resist uncoiling.
This natural inbuilt stress resists load at an even rate and makes them suitable for use in retractor mechanisms.
Common applications include counterbalance springs, car seat belt and cable retractors.
Constant-force springs are usually tightly coiled on a drum and either the free end or the drum can be attached to the load.
Four lifecycle ranges are offered, 2500, 4000, 13000 and 25000, covering loads from 0.3 to 7.48kg.
Lengths vary from 356 to 1524mm, thicknesses from 0.10 to 0.51mm and widths span the range 6.35 to 31.75mm.
Wave springs perform a similar function to compression springs but they take up to approximately 50% less compressed height space thanks to a sinewave design that allows tangential contact.
These springs also offer greater control of axial movement and consistent load transfer.
Produced in stainless steel type 17-7 PH, Lee Spring's wave springs offer optimum performance in static or slightly dynamic applications where space is critical or where radial and axial tolerances are tight.
Stock sizes range from rod sizes of 6.35 to 25.40mm to suit hole diameters from 9.53 to 31.75mm and in spring rates from 0.81 to 5.33kg/mm. Request a free brochure from Lee Spring ...
