Thousands of performance spring products
New high performance beryllium copper battery springs, REDUX wave springs, constant force springs and more sizes of stainless steel Lite Pressure compression springs have been added to Lee Spring's latest catalogue. The new product listings amount to hundreds of additional items that swell the catalogue to 172 pages containing over 16,500 different types of spring including compression, extension, torsion and Belleville spring washers plus engineers spring selection kits.
Over 200 new sizes of REDUX wave springs have been included and extend the maximum hole diameter in which they will operate to 44.45mm (1.75in). Wave springs perform a similar function to compression springs but they take up to approximately 50% less compressed height. Manufactured in stainless steel type 17-7 PH these springs offer optimum performance in static or slightly dynamic applications where space is critical or where radial and axial tolerances are tight.
Manufactured from high yield 301 stainless steel strip, constant force springs exert a near constant restraining force. The springs are usually tightly coiled on a drum and either the free end or the drum can be attached to the load. Four life cycle ranges are offered covering loads from 1.02 to 73.42N (0.23 to 16.50Ib). Typical applications include counterbalance springs, car seat belt and cable retractors mechanisms.
Two hundred more sizes of the company's Lite Pressure compression springs in type 316 stainless steel have also been added. Designed to meet demands for compression springs combining low spring rates with large diameters these high index springs deliver from 7kPa to 35kPa pressure at 80% deflection. Typical applications include valves, pistons, syringes, motor brushes, dispensers, contacts and toys.
Lee Spring's custom spring design and manufacturing service has also been strengthened with a dedicated email and technical team in place to handle the provision of tailored solutions. Full details are included along with a suite of reproducible specification forms for spring variants covering compression, extension, torsion, conical, swivel hook, drawbar, battery, wave, constant force and Belleville spring washers. Completing the catalogue are several data pages featuring a specifications and tolerance guide, glossary, geometric solutions, conversion data and mathematical symbols.
