Extension Spring: OD 2.01 mm, FL 22.5 mm, Stainless Steel

Instrument Extension Series (metric)

Precision Springs for Precision Products.

Lee Spring EIM025A 06 S is a precision extension spring from the Instrument Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 2.01-mm outside diameter (0.079 inch) with 1.5-mm loop inside diameter (0.059 inch) and extends from a free length of 22.5 mm (0.886 inch) to a maximum extended length of 51.33 mm (2.021 inch). Made from Stainless Steel with a 0.25-mm wire diameter (0.01 inch), the spring delivers a spring rate of 0.09 N/mm (0.516 lb/inch) through its 73.8 total coils with an initial tension of 0.222 N (0.05 lb) for predictable extension behavior. The spring supports a maximum load of 2.825 N (0.635 lb) at full extension with a body length of 19 mm (0.748 inch). The spring features Random loop position and Passivate per ASTM A967 finish for optimal performance.
