Instrument Compression Series (inch) Compression Springs

Precision Springs for Precision Products .

Lee Spring CI 010EG 01S is a precision compression spring from the Instrument Compression Series (inch), engineered for applications requiring reliable performance in moderate-load scenarios. This spring features an 0.218-inch outside diameter (5.54 mm) with a 0.234-inch hole diameter (5.94 mm) and extends to a free length of 0.25 inch (6.35 mm), making it ideal for instruments and assemblies where consistent and precise compression characteristics are critical. Made from Stainless Steel with a 0.01-inch wire diameter (0.25 mm), the spring delivers a spring rate of 0.991 lb/inch (0.174 N/mm) through its 1.4 active coils out of 3.4 total coils for predictable deflection behavior. The spring compresses to a solid height of 0.044 inch (1.12 mm) while supporting a maximum load of 0.204 lb (0.91 N) at full compression. The spring has Squared ends and a Passivate per ASTM A967 finish for optimal performance.

About the Compression Spring Instrument Series

The Lee Spring Instrument Series includes a wide range of size and rate combinations in a smaller, highly precise spring design. Selections are sorted in ascending order to mating hole/bore diameter sizes. Instrument Compression Springs are available in both inch and metric series. Inch 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 made from coated wire or 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. Lee Spring Instrument Compression Springs feature squared ends. A squared end, also called a closed end, is made by reducing the coil pitch of the ends to zero. Squareness influences how a force produced by the spring can be transferred to adjacent parts

Instrument Compression Series (inch) Compression Springs have useful applications in various industries, including:

  • Medical devices
  • Firearms
  • Pharmaceutical delivery devices
  • Lighting and electrical control
  • Petro-chemical processes
  • Communication devices
  • Aerospace
  • Testing and measurement equipment
  • Marine applications
  • Automotive
  • Locks and security devices
  • Precision Instruments
  • Hardware

...and many more applications
