PRODUCTS SPRINGS & SHOCK ABSORBERS DISC SPRINGS FOR A WIDE RANGE OF APPLICATIONS
With more than 100 years of experience in the production of high-quality discs springs, Schnorr’s products are used in a wide range of demanding applications in the aerospace, automotive, electrical, marine and rail industries. Available in the UK from IEC, the springs are manufactured to EN 16983 and 16984 from high quality spring
steels. These are available in standard sizes ranging from 6mm to 250mm OD, with special sizes to 1000mm OD and 80mm thick. For aggressive conditions, high alloyed materials are available; and, if required, heat or corrosion resistant materials such as Inconels and Nimonics are used. Slotted and non- slotted springs for preloading ball bearings are also available. The company’s expertise in the manufacture and heat treatment of its springs ensures that they are particularly suitable for dynamic loadings – a common area of failure for less well-made springs. The company can also supply tailor-made solutions to meet a customer’s exact needs.

WAVE SPRING SOLUTIONS Available from
TFC, Crest-to- Crest wave
springs operate as a load bearing
device, utilising a bending moment instead of relying on torsion. Providing the same force and deflection as traditional springs, this technology cuts material usage by up to 50%, while providing a lightweight and versatile product that can solve problems and enhance new product design. Edge coiling spring-tempered flat wire is used
to form the Single Turn springs, and this is said by the company to be more durable, precise and
repeatable than its stamped counterparts. The wave springs come in a variety of styles.
Popular types include: Crest-to-Crest wave springs; Crest-to-Crest wave springs + shim ends – reduce height and provide 360˚ surface contact; Single Turn wave springs – gap and overlap styles to replace stamp wave washers; Wavo Springs – round wire instead of flat, provides higher forces than single turn wave springs; Linear Springs – straight lengths to obtain axial pressure; and Nested wave springs – pre-stacked springs from a single continuous filament.

position after the cards have been ejected. The lighter it is the faster it can operate, so the compression springs perform a vital function in managing the forces involved. Needing to withstand aggressive
cleaning fluids, a special high grade of stainless steel was used for the springs.

IMPROVING PRODUCTION
Thurne’s CD Mono Card Dispenser slices and places bacon onto backing cards (L-Boards) used for the display or promotion of customer facing information, etc. For this, Lee Spring was able to create a spring set that released the potential speed of the dispenser while helping ensure machine reliability. The springs are used to shuttle cards quickly sideways and to position them accurately. They are then relied on to return the carriage to its correct
