Technical Summary of Smalley C/CS Series Crest-To-Crest® Springs

1. Product Overview

The document details the specifications and ordering information for Smalley C/CS Series Crest-To-Crest® Springs, designed for various engineering applications. These springs feature a radial wall, multi-wave design and are available in carbon steel and 17-7 PH stainless steel materials.

2. Material and End Options

Materials: Carbon Steel (default) and 17-7 PH Stainless Steel (indicated by suffix "-S17")
End Configurations: Plain ends (prefix "C") and squared-shim ends (prefix "CS")
Note: Certain part numbers marked with an asterisk (*) are not available with shim ends.

3. Dimensional and Performance Specifications

All dimensions are in inches unless otherwise noted. Key parameters include:

Operates in Bore Diameter: Internal diameter where the spring fits, ranging approximately from 1.125" to 2.000".
Clears Shaft Diameter: Shaft diameter clearance, ranging from 0.850" to 1.600".
Radial Wall Thickness: Thickness of the spring's radial wall.
Number of Waves and Turns: Multi-wave design with 3 to 20 waves, influencing load distribution and spring characteristics.
Wire Thickness: Ranges from 0.012" to 0.024".
Load at Work Height: Load exerted by the spring at its working height, ranging from 9 lb to 629 lb.
Free Height: Height of the spring when unloaded, from 0.300" up to 4.5".

4. Load Ratings and Size Series

The document provides extensive tables cataloging spring models with detailed mechanical properties, enabling precise selection based on application needs. Representative series include:

C112 Series: Bore 1.125", shaft 0.850", load 12–30 lb, wire thickness 0.012"–0.018".
C125 Series: Bore 1.250", shaft 1.000", load 12–60 lb, wire thickness 0.012"–0.019".
C137 Series: Bore 1.375", shaft 1.030", load 15–35 lb, wire thickness 0.012"–0.018".
C150 Series: Bore 1.500", shaft 1.140", load 20–60 lb, wire thickness 0.016"–0.018".
C175 Series: Bore 1.750", shaft 1.340", load 25–90 lb, wire thickness 0.018"–0.024".
C200 Series: Bore 2.000", shaft 1.600", load 25–90 lb, wire thickness 0.018"–0.024".

5. Ordering Instructions

Use prefix "C" for plain ends and "CS" for squared-shim ends.
Add suffix "-S17" to specify 17-7 PH stainless steel material.
Reference pages 134-135 for detailed ordering procedures (not included in this excerpt).
No tooling charges apply for special orders, facilitating customization.

6. Key Recommendations and Limitations

Dimensions and load ratings are theoretical and should be validated in actual application conditions.
Multi-wave design enhances load distribution and spring performance.
Some part numbers are not available with shim ends; verify availability before ordering.
Critical dimensions such as free height and work height must be considered for proper spring function.

7. Summary of Critical Parameters
