Selection to Match Your Needs

Lee Spring LEM080CF 04 S is a precision extension spring from the Standard Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 8.99-mm outside diameter (0.354 inch) with 7.42-mm loop inside diameter (0.292 inch) and extends from a free length of 44.6 mm (1.756 inch) to a maximum extended length of 130.2 mm (5.126 inch). Made from Stainless Steel with a 0.79-mm wire diameter (0.031 inch), the spring delivers a spring rate of 0.159 N/mm (0.91 lb/inch) through its 40 total coils with an initial tension of 2.273 N (0.511 lb) for predictable extension behavior. The spring supports a maximum load of 15.836 N (3.56 lb) at full extension with a body length of 32.28 mm (1.271 inch). The spring features Inline loop position and Passivate per ASTM A967 finish for optimal performance.

Extension Springs: Standard Series

The Lee Spring Standard Extension Spring Series includes a wide range of size and rate combinations and in both inch and metric sizes. Standard Series springs are available in Music Wire, Type 302 Stainless Steel and Type 316 Stainless Steel. Metric Series springs are available in Music Wire and Type 302 Stainless Steel. The Music Wire springs are provided with a plating finish for light corrosion resistance.
