MEDIUM LOAD COLOR CODE GRAY MEDIUM LOAD PLUS COLOR CODE BEIGE MEDIUM HEAVY LOAD COLOR CODE PURPLE HEAVY LOAD COLOR CODE BLACK EXTRA HEAVY LOAD COLOR CODE ORANGE Only HEFTY Die Springs offer you the economy of round wire and the durability of chrome silicon or music wire, plus the World Class Service you ve come to expect from Lee Spring. HEFTY Die Springs are ideal for any high stress, heavy load application. Our customers have found that our high-performance HEFTY Die Springs are also great for use in such diverse applications as clutches, brakes, farm machinery and aircraft mechanisms. And Lee Spring offers five different types of durable HEFTY Die Springs with different load ratings to fit standard diameters. Recent independent testing conducted by the Institute of Spring Technology has proven that Lee Spring s HEFTY Die Springs have a life-expectancy equal to traditional rectangular wire die springs. To find out what HEFTY Die Springs can do for your application as well as your budget, call us at , or visit us at TIPS FOR SELECTING AND USING HEFTY DIE SPRINGS a) Determine if springs will be used for short run, average cycle long run, rapid cycle or extra stress and then refer to appropriate section (medium load, etc.). b) Use as many springs in the die as space permits with the least amount of deflection. c) The more rapidly a spring is cycled, the greater the need to operate within the ideal operating range. d) Make sure hole and rod sizes in die are properly matched with spring. Faulty spring guidance will cause buckling and possible spring failure. e) Preventive maintenance on dies should be performed on a regular basis and die springs should be replaced at appropriate intervals to prevent downtime. f) Replace all springs in a die at the same time. This will insure an even distribution of the load. g) Do not rework die springs by grinding the inside or outside diameter or by cutting off coils. This could result in premature spring failure and possible die damage. h) Please note that load calculations for HEFTY springs are based on a deflection that is a percentage of the Free Length. Load at 50% Deflection should be interpreted to mean 50% deflection of the Free Length. The following is a sample calculation for the Load at 50% Deflection for Part Number LHL 375A 01, where Free Length = 1 inch and Rate = 56 lb/in and 50% of Free Length = 1/2 inch. The load is calculated by using the formula (found on page 3): P = R x F or R x F = P (i.e. 56 lb/in x 1/2 in = 28 lb.) 163
