Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM180DF 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 11.99-mm outside diameter (0.472 inch) with 8.38-mm loop inside diameter (0.33 inch) and extends from a free length of 87.2 mm (3.433 inch) to a maximum extended length of 134.8 mm (5.307 inch). Made from Stainless Steel with a 1.8-mm wire diameter (0.071 inch), the spring delivers a spring rate of 2.1 N/mm (11.99 lb/inch) through its 40 total coils with an initial tension of 17.851 N (4.013 lb) for predictable extension behavior. The spring supports a maximum load of 117.433 N (26.4 lb) at full extension with a body length of 73.94 mm (2.911 inch). The spring features Inline loop position and Passivate per ASTM A967 finish for optimal performance.
