Lee Spring announce expansion of standard Die Spring range

07 October 2016

As suppliers of ex-stock die springs, Lee Spring are keen to expand its standard ranges – in this case the Die Spring catalogue has been extended with 71 new items.

These new items in music wire or OTCS (chrome silicon steel) reduce the gap between different standard lengths with additional options over 6in lengths, so making it easier to choose a suitable standard spring. New lengths include 4, 5, 6, 7, 7.5 and 8in with eight different outer diameters to suit medium (grey), medium-heavy (purple), heavy (black) and extra heavy duty (orange) loadings.

Similarly to other Lee Spring die springs the new sizes are generally priced at 1/3 to 1/2 less than the cost of comparable rectangular wire springs, offering users a distinct value advantage. In independent testing conducted by the Institute of Spring Technology, Lee Spring’s die springs demonstrated a life-expectancy equal to traditional rectangular wire die springs.

Ex-stock die springs are not solely used in dies but find application in clutches, brakes, farm machinery and aircraft mechanisms. They are ideal for use as die springs or as heavy duty compression springs for any high stress, heavy load application.

Lee Spring standard die springs are shot-peened for extended life and pre-set to prevent loss of length in service. Importantly they are supplied with closed and ground ends to provide square seating with a large bearing surface – they are suitable for orientation either way up and for use in heavy duty applications. They are powder coated for corrosion protection. Custom variants are also available.
