Wave spring RFQ data for engineering review
A clear RFQ should describe the available space, required load and working environment. If you only have a sample, photos and measured OD, ID, height and wire section are enough to start.
Request QuoteLoad and working height
Provide target load, installed height, maximum compression height, expected travel and the load points that matter most.
Material and service
Share temperature, media, corrosion, lubrication, cleaning exposure, cycle duty, finish needs and storage conditions.
Quantity and documents
Tell us sample quantity, batch volume, delivery target, material certificate, dimensional report and load test requirements.

Wave Spring Specification and RFQ Data Checklist
| Specification item | Why it matters | Typical RFQ note |
|---|---|---|
| Spring form | Single-turn, multi-turn, nested, open-end or plain-end geometry changes load, travel, installation and seating. | If unsure, send sample photos and describe the function in the assembly. |
| OD, ID and radial width | Sets the fit with shaft, housing, bore, groove and mating components. | Send drawing dimensions, groove dimensions or measured sample photos. |
| Wire thickness and wire width | Controls stress, spring rate, manufacturability and available radial space. | Measure the flat-wire section or provide the drawing tolerance. |
| Free height, working height and solid height | Defines usable travel, load window and safety margin before over-compression. | Include installed height, maximum compression height and available axial space. |
| Target load at working height | Controls spring rate, wave count, turn count, layer count and material choice. | If unknown, describe the preload function and the problem being solved. |
| Number of waves, turns and layers | Affects load-deflection curve, travel, stability and nested or multi-turn behavior. | State existing design data if it is a replacement project. |
| End form and seating face | Open ends, overlap ends and plain ends behave differently against grooves and flat mating faces. | Share whether the spring seats against a flat face, groove, bearing ring or rotating part. |
| Material and environment | Affects corrosion resistance, temperature capability, relaxation, fatigue and cleanliness. | Share temperature, media, moisture, chemicals, cleaning exposure and expected life. |
| Surface finish and edge condition | Finish and edge condition can affect corrosion, friction, seating and fatigue performance. | Ask for passivation, oiling, black oxide, phosphating or other finish only when the service requires it. |
| Quantity, samples and documents | Helps plan sample route, production method, inspection and commercial review. | State sample quantity, batch volume, material certificate, dimensional report and load test needs. |
Wave spring load is sensitive to geometry, material condition, end form, friction and installation guidance. Final dimensions should be confirmed against the real assembly.
Wave Spring Material Review Options
| Material family | Typical grades | When to review |
|---|---|---|
| Spring steel | Carbon spring steel / alloy spring steel | Cost-sensitive preload in controlled indoor service. |
| Stainless steel | 301 / 304 / 316 / 17-7PH | Moisture, clean equipment, light corrosion or stronger stainless spring performance. |
| Nickel alloys | Inconel X-750 / Inconel 718 | High temperature, relaxation resistance, valve duty or severe service. |
| Corrosion-resistant alloys | Hastelloy C-276 | Chlorides, acid, scrubber service or aggressive chemical environments. |
| Finish options | Passivation / oiling / black oxide / phosphating by review | Reviewed when corrosion, handling, storage or mating-surface behavior matters. |
Custom wave spring sourcing notes
A wave spring is a flat-wire spring used when an assembly needs axial force but cannot accept the height of a traditional coil spring. Buyers usually search for custom wave springs when the available space, load, travel or material is already limited by the equipment design.
For an accurate quotation, send OD, ID, radial width, wire thickness, wire width, free height, working height, target load, material, temperature, cycle duty, surface finish, quantity and the drawing or sample photos. If the design is still open, share the shaft, housing or groove dimensions and the function of the spring in the assembly.
Wave springs are often reviewed for bearing preload, mechanical seals, valve and actuator assemblies, pumps, compressors, gearboxes, motors, connectors and compact mechanisms. Stainless steel, 17-7PH and nickel alloy options should be reviewed before geometry is locked when corrosion, heat or relaxation matters.
Common Product Questions
What is a wave spring?
A wave spring is a flat-wire compression spring formed into waves around a ring. It can provide axial force in a shorter space than many coil spring designs.
When should I use a wave spring instead of a coil spring?
Wave springs are useful when the assembly needs spring force but axial height is limited, such as bearings, seals, connectors, pumps, gearboxes and compact mechanisms.
What is the difference between a wave spring and a Belleville washer?
A Belleville washer is a conical disc spring that carries load through disc deflection. A wave spring uses waves in flat wire to provide travel and load in a low-height space. The better choice depends on load, travel, diameter, stress and assembly guidance.
What data is needed for a custom wave spring RFQ?
Useful RFQ data includes OD, ID, radial width, wire thickness, free height, working height, target load, material, temperature, cycle duty, quantity, drawing and the mating shaft or housing dimensions.
Can wave springs be made from Inconel or Hastelloy?
Yes. Stainless steel is common, but Inconel X-750, Inconel 718, Hastelloy C-276 and other alloys can be reviewed when heat, corrosion, relaxation or long service life is critical.
How do I choose single-turn, multi-turn or nested wave springs?
Single-turn wave springs are usually reviewed for low-height preload and light travel. Multi-turn wave springs are useful when more travel is needed. Nested wave springs are reviewed when the available height is limited but the target load is higher.
Can FeTech quote a wave spring from a sample instead of a drawing?
Yes. Clear photos plus measured OD, ID, radial width, wire thickness, wire width, free height and installed height are enough to start a preliminary review. A drawing is still preferred before final production.
Why is installed height important for a wave spring RFQ?
Wave spring force is normally specified at a working height, not only by free height. The installed height, maximum compression height and target load point help engineers check travel, stress and over-compression risk.
