EUROPE ASIA NORTH & SOUTH AMERICAOur stock spring product listing continues to grow. In this catalogueyou’ll find hundreds of new springs including high performanceberyllium copper battery springs, REDUX wave springs, constantforce springs and more sizes of 316 stainless steel Lite Pressurecompression springs. In total over 16000 different types of spring.Beryllium copper, one of the hardest, strongest and most hardwearing copper alloys, improves the physical properties of ourlatest battery springs while a silver coating enhances electrical andthermal conductivity performance and makes soldering easier. Thesehigh performance battery springs will appeal to engineers who aredeveloping devices where exceptional endurance and ruggednessare key requirements.Both our standard and beryllium copper spring types are designedto adjust to varying battery lengths and provide secure, lowcontact resistance and dependable connections. All provide fast,efficient and reliable contacts in most situations where portablepower is required, for example, in self contained moulded batterycompartments or tailored applications. Our standard range isproduced in nickel coated music wire to harmonize with the nickelplated containers commonly used in the manufacture of alkalinebatteries. The use of similar materials prevents galvanic corrosionand enhances wear resistance. The nickel also adds corrosionprotection and superior electrical conductivity.Four mounting configurations are offered – interior, exterior,adjustable and double - all of which have been developed to workwith the most popular battery sizes.restraining force. Usually they are tightly coiled on a drum andeither the free end or the drum is attached to the load. Four lifecycle ranges are offered covering loads from 1.02 to 73.42N (0.23 to16.50Ib). Typical applications include counterbalance springs, car seatbelt and cable retractor mechanisms.Two hundred additional sizes of Lite Pressure compression springsin Type 316 stainless steel have been added. Designed to meetdemands for compression springs combining low spring rates withlarge diameters these high index springs deliver from 7 to 38kPapressure @ 80% deflection. Typical applications include valves,pistons, syringes, motor brushes, dispensers, contacts and toys.Lee Spring’s custom spring design and manufacturing service hasalso been strengthened with a dedicated email and technical teamin place to handle the provision of tailored solutions. Full details areincluded along with a suite of reproducible specification forms forspring variants covering compression, extension, torsion, conical,swivel hook, drawbar, battery, wave, constant force and Bellevillespring washers.As previously we feature compression, die, extension, continuouslength, torsion springs and Belleville washers.Sensibly our stock spring choice covers the most commonly requestedsizes but we also offer ‘specials’ based on our stock range as wellas tailored conical springs, swivel hook springs, drawbar springsconstant force and wave springs.Completing the catalogue are several data pages which include aspecifications and tolerance guide, glossary, geometric solutions,conversion data and mathematical symbols.The breadth of choice in this new catalogue confirms Lee Spring’sposition as the leading global supplier of springs.REDUX wave springs perform a similar function to compressionsprings except they take up to approximately 50% less compressedheight. Manufactured in stainless steel type 17-7 PH our wavesprings offer optimum performance in static or slightly dynamicapplications where space is critical or where radial and axialtolerances are tight.Also new in this catalogue are constant force springs. Produced inhigh yield 301 stainless steel strip these springs exert a near constantCustom spring design and manufactureSprings can be designed to an almost unlimited variety ofconfigurations and over the years Lee Spring have manufacturedliterally millions of ‘custom’ designed springs.Custom designs are normally considered when either theperformance characteristics required (e.g. environmental conditions,product life cycle, and load capabilities) or physical size andconfiguration requirements exceed the scope of what is availablefrom our comprehensive stock range.2Sales Hotline: Tel: +44 (0)118 978 1800 Fax: +44 (0)118 977 4832 or order online @ www.leespring.co.uk
