Selection to Match Your Needs

Lee Spring LEM200DB 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 10.01-mm outside diameter (0.394 inch) with 5.99-mm loop inside diameter (0.236 inch) and extends from a free length of 31.6 mm (1.244 inch) to a maximum extended length of 37.47 mm (1.475 inch). Made from Music Wire with a 2.01-mm wire diameter (0.079 inch), the spring delivers a spring rate of 31.801 N/mm (181.58 lb/inch) through its 10 total coils with an initial tension of 32.939 N (7.405 lb) for predictable extension behavior. The spring supports a maximum load of 220.009 N (49.46 lb) at full extension with a body length of 22.07 mm (0.869 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
