Wave Spring: OD 37.85 mm, FL 21.34 mm, Stainless Steel Type 17-7 PH

REDUX™ Wave Series (metric)

Redux Wave Springs with Big Performance.

Lee Spring LWM40 100 2134S is a precision wave spring from the REDUX™ Wave Series (metric), engineered for applications requiring controlled spring force in extremely limited axial space with superior load-to-height ratio. This spring features a 37.85-mm outside diameter (1.49 inch) with a 40-mm hole diameter (1.575 inch) designed to work over a 30-mm rod diameter (1.181 inch). Made from Stainless Steel Type 17-7 PH with a 0.41-mm wire thickness (0.016 inch), the spring provides a free length of 21.34 mm (0.84 inch) and compresses to a working height of 6.73 mm (0.265 inch) with a solid height of 3.25 mm (0.128 inch). The spring delivers a spring rate of 6.85 N/mm (39.113 lb/inch) with a nominal load of 100 N (22.481 lb) through its 3.5 waves per turn configuration and 3.38 -mm radial wall (0.133 inch). With a Passivate per ASTM A967 finish, this wave spring provides consistent performance for applications requiring maximum force in minimal space, including bearing preload, valve assemblies, and precision mechanical systems where conventional coil springs cannot achieve the required load-to-height performance.

REDUX™ Wave Springs: Space-Saving Compression Spring Solutions

Lee Spring's REDUX™ Wave Springs

Lee Spring's REDUX™ Wave Springs deliver superior performance in space-constrained environments where traditional compression springs fall short. These innovative wave springs are specifically engineered to replace conventional round wire compression springs in applications demanding precise load deflection specifications within minimal installation space.

Key Benefits of REDUX™ Wave Springs

  • Space Optimization: Up to 50% reduction in assembly size and weight compared to traditional coil springs.
  • Precision Engineering: Manufactured from premium Type 17-7 Stainless Steel flat wire with continuous precise coils, uniform diameters, and wave heights for consistent performance.
  • Superior Load-to-Space Ratio: Equal deflection and load characteristics in a dramatically reduced operating height.

Technical Specifications

Constructed from Stainless Steel Type 17-7 PH, a precipitation-hardened alloy that provides exceptional strength and corrosion resistance. Springs utilize pre-tempered flat wire formed into continuous coils, eliminating weak points found in welded or joined spring designs.

These wave springs operate reliably at temperatures up to 650°F (340°C), making them suitable for high-temperature applications where conventional springs may fail. All springs receive a passivated surface finish that enhances corrosion resistance and provides a clean, professional appearance.

The continuous coil construction with uniform diameter and wave heights ensures predictable load-deflection curves and consistent performance across the entire spring range. This precision manufacturing approach eliminates the variability often encountered with traditional compression spring production methods.

Applications for Wave Springs

  • Space-critical assemblies requiring load deflection control
  • High-temperature applications up to 650°F
  • Precision instruments and devices
  • Automotive components
  • Aerospace applications
  • Medical devices
  • Electronic assemblies
