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

1. Product Description and Options

The C/CS Series Crest-To-Crest® Springs are specialized multi-wave springs designed for precise radial and axial applications. Manufactured in the USA by Smalley, these springs come in two end configurations: plain ends (prefix "C") and squared-shim ends (prefix "CS"). Material options include Carbon Steel (default) and 17-7 PH Stainless Steel (suffix "-S17"). All dimensions are provided in inches.

2. Key Parameters and Definitions

Operates in Bore Diameter: Internal diameter where the spring fits.
Clears Shaft Diameter: Shaft diameter that the spring clears.
Radial Wall Thickness: Thickness of the spring wall in the radial direction.
Multi-Wave: Number of waves in the spring, influencing flexibility and load capacity.
Wire Thickness: Thickness of the wire forming the spring.
Turns: Number of coils or turns in the spring.
Load at Work Height: Load exerted by the spring at its working height, measured in pounds.
Free Height: Height of the spring when uncompressed.
Spring Rate: Theoretical spring rate in pounds per inch (lb/in).

3. Product Dimensions and Performance Data

The document provides extensive tabulated data for various spring models, detailing bore diameters (ranging from 1.125" to 2.000"), shaft clearances, number of waves and turns, wire thickness, radial wall thickness, load at work height, free height, and spring rate. These data enable precise selection based on application requirements.

4. Ordering Information

Use prefix "C" for plain ends and "CS" for squared-shim ends.
Add suffix "-S17" to specify 17-7 PH stainless steel material.
Special orders are available without tooling charges.
Detailed ordering procedures are referenced but not included (pages 134-135).

5. Notes and Limitations

Some part numbers marked with an asterisk (*) are not available with shim ends.
Spring rates are theoretical values provided for design guidance.
Reference dimensions assist in engineering design but should be verified for critical applications.
Stock items are available in both carbon steel and 17-7 PH stainless steel.

6. Manufacturer and Contact

All springs are manufactured in the USA by Smalley. Contact number: 847.719.5900.

7. Key Recommendations and Best Practices

Select spring size based on bore diameter and shaft clearance to ensure proper fit.
Match load at work height and free height to application requirements for optimal performance.
Choose material considering corrosion resistance and mechanical properties.
End type selection (plain or squared-shim) should align with installation and mounting needs.

8. Example of Critical Parameters (1.125" Bore Diameter)

Part Number	Clears Shaft Diameter (in)	Load at Work Height (lb)	Free Height (in)	Spring Rate (lb/in)
C112-L1	0.850	12	0.300	78
C112-L10	0.850	12	2.000	12
C112-M1	0.850	20	0.300	143
C112-H1	0.850	30	0.300	246

This table illustrates how variations in wire thickness and number of turns affect load capacity and spring rate.

Conclusion

This document is a comprehensive technical reference for engineers and purchasers to select and order Smalley C/CS Series Crest-To-Crest® Springs. It provides detailed dimensional and load data, material and end finish options, and ordering guidelines to ensure precise specification of compact, high-performance wave springs.
