Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM160CD 03 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 8-mm outside diameter (0.315 inch) with 4.83-mm loop inside diameter (0.19 inch) and extends from a free length of 49.3 mm (1.941 inch) to a maximum extended length of 61.49 mm (2.421 inch). Made from Music Wire with a 1.59-mm wire diameter (0.0625 inch), the spring delivers a spring rate of 10.2 N/mm (58.24 lb/inch) through its 25 total coils with an initial tension of 21.81 N (4.903 lb) for predictable extension behavior. The spring supports a maximum load of 145.991 N (32.82 lb) at full extension with a body length of 41.28 mm (1.625 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
