Selection to Match Your Needs

Lee Spring LEM140ED 05 M is a precision extension spring from the Standard Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 15.01-mm outside diameter (0.591 inch) with 12.22-mm loop inside diameter (0.481 inch) and extends from a free length of 105 mm (4.134 inch) to a maximum extended length of 292 mm (11.496 inch). Made from Music Wire with a 1.4-mm wire diameter (0.055 inch), the spring delivers a spring rate of 0.259 N/mm (1.48 lb/inch) through its 60 total coils with an initial tension of 8.501 N (1.911 lb) for predictable extension behavior. The spring supports a maximum load of 57.115 N (12.84 lb) at full extension with a body length of 85.22 mm (3.355 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 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.
