Extension Spring: OD 10.01 mm, FL 68.91 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM140DB 04 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 10.01-mm outside diameter (0.394 inch) with 7.21-mm loop inside diameter (0.284 inch) and extends from a free length of 68.91 mm (2.713 inch) to a maximum extended length of 115.09 mm (4.531 inch). Made from Music Wire with a 1.4-mm wire diameter (0.055 inch), the spring delivers a spring rate of 1.539 N/mm (8.79 lb/inch) through its 40 total coils with an initial tension of 12.66 N (2.846 lb) for predictable extension behavior. The spring supports a maximum load of 83.582 N (18.79 lb) at full extension with a body length of 57.28 mm (2.255 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.
