Extension Spring: OD 4.5 mm, FL 16.99 mm, Stainless Steel

Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM045B 02 S is a precision extension spring from the Standard Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 4.5-mm outside diameter (0.177 inch) with 3.58-mm loop inside diameter (0.141 inch) and extends from a free length of 16.99 mm (0.669 inch) to a maximum extended length of 37.31 mm (1.469 inch). Made from Stainless Steel with a 0.46-mm wire diameter (0.018 inch), the spring delivers a spring rate of 0.256 N/mm (1.46 lb/inch) through its 22.4 total coils with an initial tension of 0.519 N (0.1166 lb) for predictable extension behavior. The spring supports a maximum load of 5.706 N (1.2828 lb) at full extension with a body length of 9.83 mm (0.387 inch). The spring features Random loop position and Passivate per ASTM A967 finish for optimal performance.

Extension Springs: Standard Series

The Lee Spring Standard Extension Spring Series includes a wide range of size and rate combinations and in both inch and metric sizes. Standard Series springs are available in Music Wire, Type 302 Stainless Steel and Type 316 Stainless Steel. Metric Series springs are available in Music Wire and Type 302 Stainless Steel. The Music Wire springs are provided with a plating finish for light corrosion resistance. The Type 302 Stainless Steel springs are passivated, while Type 316 Stainless Steel springs are passivated and ultrasonically cleaned.
