Selection to Match Your Needs

Lee Spring LEM050AB 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 3.51-mm outside diameter (0.138 inch) with 2.49-mm loop inside diameter (0.098 inch) and extends from a free length of 289.99 mm (11.417 inch) to a maximum extended length of 500 mm (19.685 inch). Made from Music Wire with a 0.48-mm wire diameter (0.019 inch), the spring delivers a spring rate of 0.051 N/mm (0.29 lb/inch) through its 560 total coils with an initial tension of 1.77 N (0.398 lb) for predictable extension behavior. The spring supports a maximum load of 12.01 N (2.7 lb) at full extension with a body length of 285.01 mm (11.221 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
