Selection to Match Your Needs

Lee Spring LEM200HB 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 22-mm outside diameter (0.866 inch) with 17.98-mm loop inside diameter (0.708 inch) and extends from a free length of 80.8 mm (3.181 inch) to a maximum extended length of 192.81 mm (7.591 inch). Made from Music Wire with a 2.01-mm wire diameter (0.079 inch), the spring delivers a spring rate of 0.811 N/mm (4.63 lb/inch) through its 25 total coils with an initial tension of 16.111 N (3.622 lb) for predictable extension behavior. The spring supports a maximum load of 106.98 N (24.05 lb) at full extension with a body length of 52.17 mm (2.054 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
