Extension Spring: OD 7.01 mm, FL 22.1 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM140CA 01 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 7.01-mm outside diameter (0.276 inch) with 4.22-mm loop inside diameter (0.166 inch) and extends from a free length of 22.1 mm (0.87 inch) to a maximum extended length of 26.47 mm (1.042 inch). Made from Music Wire with a 1.4-mm wire diameter (0.055 inch), the spring delivers a spring rate of 22.301 N/mm (127.34 lb/inch) through its 10 total coils with an initial tension of 16.881 N (3.795 lb) for predictable extension behavior. The spring supports a maximum load of 114.008 N (25.63 lb) at full extension with a body length of 15.37 mm (0.605 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance. Extension Springs: Standard SeriesThe 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. The Type 302 Stainless Steel springs are passivated, while Type 316 Stainless Steel springs are passivated and ultrasonically cleaned. Lee Spring's Stock Extension Springs are supplied with full diameter loops (either to machine or crossover center style) at a random position with the exception of Metric Extension Springs which are specified to meet DIN Standards. Loop openings are approximately one wire diameter and the direction of wind is factory optional. Standard Extension Series (metric) Extension Springs have useful applications in various industries, including:
