Extension Spring: OD 6.3 mm, FL 70 mm, Stainless Steel

Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM080C 13 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 6.3-mm outside diameter (0.248 inch) with 4.72-mm loop inside diameter (0.186 inch) and extends from a free length of 70 mm (2.756 inch) to a maximum extended length of 132.49 mm (5.216 inch). Made from Stainless Steel with a 0.79-mm wire diameter (0.031 inch), the spring delivers a spring rate of 0.284 N/mm (1.62 lb/inch) through its 69.7 total coils with an initial tension of 2.705 N (0.608 lb) for predictable extension behavior. The spring supports a maximum load of 20.416 N (4.5898 lb) at full extension with a body length of 60.55 mm (2.384 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.
