Canted Coil Spring Seals Overview

Canted Coil Springs also known as: Slant Coil Spring, Wire Wound Spring, Wound Spring, Slant Coil.

Handa energizers are Canted (or slanted) Coil springs that produce a very flat load curve when compressed. They are used to energize U-cup seals and other components providing constant predictable loads throughout their wide deflection range. The Slant Coil spring has a flat load to deflection curve which means that the force emitted stays constant over a wide deflection range. This feature makes it perfect for high-speed rotary systems or applications which require tight control of running friction or breakout. It may also be used within devices that require a quick disconnect where many engagement and disengagement cycles are necessary.

Custom sizes and materials are also available.

Materials And Plating available include:

Materials: Stainless steel (e.g., 302, 316), Platinum Iridium, MP35N, Elgiloy®, Beryllium copper, Inconel®, Hastelloy® etc.,

Plating: Gold, Silver, Tin, and Nickel plating available.

How a Canted Coil Spring Works

Canted coil springs, are engineered to deliver consistent force, uniform contact pressure, and multi-directional load support. At Handa Spring, we specialize in designing and manufacturing custom canted coil springs that meet the highest performance standards for demanding applications.

1.Constant Force Through Working Deflection Range

Canted Coil Spring Deflection Force | Handa Spring

As the spring is further compressed, its load remains relatively constant throughout the working deflection range. This continues until the maximum deflection point, where the individual coils come into contact with one another. Beyond this point, no further deflection is possible.

Unlike traditional sealing elements such as O-rings or V-springs, which exert a force that increases proportionally with deflection, Handa’s canted coil springs provide only the required force needed for mechanical retention or electrical conductivity. This results in:

Lower insertion and breakaway forces
Reduced component wear
Longer operational cycle life

This constant force profile is especially valuable in applications involving high mating cycles or sensitive assemblies.

2.Electrical Design Considerations

Canted Coil Spring Plating Data | Handa Spring

In electrical and EMI shielding applications, the performance of a canted coil spring depends not only on its geometry but also on the material and surface finish. Key design factors include:

Base wire material (e.g., stainless steel, Elgiloy®, beryllium copper)
Plating material (e.g., gold, silver, nickel)
Plating thickness

Applying a conductive plating layer over the spring’s wire significantly enhances its electrical conductivity, improves signal integrity, and ensures consistent grounding.

At Handa Spring, we offer a range of plating options to match your specific performance and corrosion resistance requirements.
