About Custom Feeder Compression Springs
A feeder compression spring advances or returns a moving element within a constrained mechanism. Its body may need a non-circular outline to fit the channel, and its end features must locate against the follower and base. Describe the complete installed path and load range: matching a free length alone does not establish reliable feeding or acceptable end-of-travel force.
Key Design Characteristics
- Provide the internal channel shape and follower contact details.
- Check the spring envelope through the full follower movement.
- Specify force at the start, intermediate positions and end of usable travel.
Choosing Between Related Designs
This page focuses on the guided feeding function. A rectangular body outline can be made from round wire and should not be confused with rectangular-section wire. Consider body shape and wire section separately.
Specification and Inspection Review
Define a functional test in the mating channel as well as dimensional and load checks. State unacceptable rubbing, snagging or permanent deformation so assembly behaviour is included in acceptance.

What to Define for This Spring
Use these product-specific inputs to describe your requirement. Final dimensions, material and performance are confirmed against the drawing and operating conditions.
| Specification item | What to define |
|---|---|
| Channel envelope | Internal width, depth, guide features and restricted regions. |
| Body geometry | Coil shape, wire size and free length. |
| End location | Follower connection and base seating details. |
| Force through travel | Required loads at identified follower positions. |
| Operating conditions | Cycle range, environment, friction and finish requirements. |

Next Steps for Your Spring Design
Once the spring style is selected, confirm how it works in the assembly, which material suits the environment, how it will be manufactured and which dimensions and performance points should be controlled on the drawing.
Materials
Choose the material for the environment
Review spring wire and surface condition with the required cycle range and contact against the channel.

Compression Springs
Rectangular-Wire Compression Springs
Compression springs made from rectangular-section wire, specified by section width, thickness, winding orientation and working load.
Compression Springs
Cylindrical Compression Springs
A straight, constant-diameter coil for predictable axial force where the spring works inside a bore, around a guide, or between two flat seats.
Compression Springs
Conical Compression Springs
A tapered compression spring for assemblies that need a changing diameter, improved stability, or a lower compressed package than a conventional straight coil can provide.
Product Questions
Feeder Compression Springs FAQ
Is matching the free length enough for replacement?
No. The channel, end interfaces and force at installed positions must also match. Record dimensions and working loads from the actual mechanism.
Does a non-circular feeder body require rectangular wire?
Not necessarily. Body outline and wire cross-section are different design choices. Identify both on the drawing.
RFQ
Send the Working Requirement
A drawing is ideal. If you do not have one yet, provide the dimensions, load or torque, travel, environment and expected quantity that matter in the assembly.
