Compression Springs Heavy Duty Series

Transcription

1 : HEAVY DUTY SERIES Compression Springs Heavy Duty Series Durable Springs Manufactured to Perform The Lee Spring Heavy Duty Series of compression springs includes a range of large size and high spring rate combinations. Selections are sorted in ascending order to mating hole/bore diameter sizes. Heavy Duty Series springs are available in Music Wire or Oil Tempered MB and Type 302 Stainless Steel. Springs in this series are pre-set to prevent length loss in operation and shotpeened for added fatigue resistance. The Music Wire/Oil Tempered MB springs are provided with a zinc plating finish for light corrosion resistance. The Type 302 Stainless Steel springs are passivated. Lee Spring Heavy Duty Series springs feature squared and ground ends. A squared end, also called a closed end, is made by reducing the coil pitch of the ends to zero. Squareness influences how a force produced by the spring can be transferred to adjacent parts. The ground ends provide flat bearing surfaces and additional stability. Squared and ground ends are particularly useful in applications in which 1) high-duty springs are specified, 2) unusually close tolerances on load or rate are needed, 3) solid height must be minimized, 4) accurate seating and uniform bearing pressures are required and 5) a tendency towards buckling must be reduced.

2 : HEAVY DUTY SERIES Compression Springs Heavy Duty Series Guide to using tables Lee Stock Number: Lee Spring Part Number, add suffix M for Music Wire or S for Stainless Steel. To Work In Hole Diameter: Suggested minimum hole size if needed for spring containment. Approx. Load at Solid Height: The load or force required to bring all coils into contact. Spring Rate: Change in load or force per unit of deflection. Price Group: Reference for price list. See fold-out section at rear of book.

Wire Diameter: In ascending order of size, within each group of outside diameters. Free Length: The overall height of the spring in the unloaded position. Solid Height: Length when fully compressed. Additional Information How to Determine Price Load at Solid Height figures are provided for reference only. During the manufacturing process all material and engineering tolerances may result in the number of coils being adjusted to maintain the correct spring rate and therefore affect solid height. It is general good practice to avoid compressing springs to their solid height in order to achieve longer life. A guide rod is recommended to prevent buckling of long springs. To figure the load at any working length based on nominal free length and spring rate use the formula: P = R x F where P is the load in lbs.; R is the spring rate in lbs per inch; F is the deflection in inches (or free length minus final spring length. 1.
