New high-performance beryllium copper (BeCu or sometimes CuBe) 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.
Hundreds of additional items swell the catalogue to 172 pages covering over 16,000 different spring types, including compression, extension, torsion and Belleville spring washers, plus engineers' spring selection kits.
Battery springs provide fast, efficient and reliable contacts. Beryllium copper, one of the hardest, strongest and most hard-wearing copper alloys, improves the physical properties of the springs, while silver plating enhances electrical and thermal conductivity performance and makes soldering easier. These high-performance battery springs will appeal to engineers who are developing devices requiring exceptional endurance and ruggedness. The springs supplement an existing range manufactured from nickel-coated music wire to match the nickel-plated containers used for most alkaline batteries. All the battery springs come in four mounting configurations - interior, exterior, adjustable and double - and are designed to adjust to varying battery lengths and provide secure, low-contact resistance and dependable connections. Custom designs can also be produced.
REDUX wave springs in over 200 new sizes have also been included, thereby extending the maximum hole diameter in which they will operate to 44.45mm (1.75inches). Wave springs perform a similar function to compression springs but they take up to approximately 50 per cent 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.
Constant force springs in high yield strength 301 stainless steel strip 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 1.02-73.42N (0.23-16.50lb). Typical applications include counterbalance springs, car seat belts and cable retractor mechanisms.
Lite Pressure compression springs in type 316 stainless steel are now available in a further 200 sizes. Designed to meet demands for compression springs combining low spring rates with large diameters, these high-index springs deliver 7-35kPa at 80 per cent 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. Full details are included in the catalogue, together with 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 guide to specifications and tolerances, glossary, geometric solutions, conversion data and mathematical symbols.
The breadth of choice in the new catalogue confirms Lee Spring's position as a leading global supplier.
