Selection to Match Your Needs

Lee Spring LEM120D 11 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 9.5-mm outside diameter (0.374 inch) with 7.11-mm loop inside diameter (0.28 inch) and extends from a free length of 89.99 mm (3.543 inch) to a maximum extended length of 168.22 mm (6.623 inch). Made from Stainless Steel with a 1.19-mm wire diameter (0.047 inch), the spring delivers a spring rate of 0.503 N/mm (2.87 lb/inch) through its 60.8 total coils with an initial tension of 5.706 N (1.2828 lb) for predictable extension behavior. The spring supports a maximum load of 44.983 N (10.1126 lb) at full extension with a body length of 75.77 mm (2.983 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.
