Selection to Match Your Needs

Lee Spring LEM075CD 08 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 8-mm outside diameter (0.315 inch) with 6.48-mm loop inside diameter (0.255 inch) and extends from a free length of 59.99 mm (2.362 inch) to a maximum extended length of 168.71 mm (6.642 inch). Made from Stainless Steel with a 0.74-mm wire diameter (0.029 inch), the spring delivers a spring rate of 0.116 N/mm (0.66 lb/inch) through its 66.3 total coils with an initial tension of 1.371 N (0.3082 lb) for predictable extension behavior. The spring supports a maximum load of 13.895 N (3.1237 lb) at full extension with a body length of 47.04 mm (1.852 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.
