O-rings and circular seals
Separate rings, verify singles and present for pickup or mandrel loading.
Flexible and surface-sensitive parts
O-ring, seal and gasket feeders for controlled assembly supply.
Separate and present flexible sealing components while managing adhesion, overlap, deformation, contamination and access for the receiving tool.
- Flexible components
- Low-marking contact
- Overlap control
- Vision or tooling
Direct answer
How are O-rings fed automatically?
O-rings can be separated and presented using purpose-tooled bowls, conveyors, flexible feeders, vision systems or dedicated magazines. The best method depends on diameter, cross-section, material, tackiness, static, deformation and the pose needed for assembly.
System and application overview
A seal can change shape while it is being handled.
Unlike a rigid component, an O-ring or gasket may stretch, fold, overlap or adhere to another part. Feeding should therefore be assessed under realistic temperature, contamination and storage conditions.
The final system may present the seal flat, on edge, centred in a nest or accessible to a gripper, mandrel or vacuum tool.
- Control overlap, sticking, static and distortion throughout the feed path
- Use contact materials that protect sealing surfaces and do not create contamination
- Define the final free-state shape and accessible pick features
- Add vision or sensors where doubles and partial overlap must be detected
Where it fits
Sealing components suited to application assessment.
Trials establish whether mechanical tooling, controlled conveying or vision-guided presentation provides the most stable result.
Flat gaskets
Control overlap and orientation of thin profiles with limited rigidity.
Rubber mouldings and plugs
Handle flexible caps, plugs, diaphragms and sealing inserts without damage.
Engineering decisions
Material behaviour changes with the environment.
Temperature, oil, mould release, static and storage pressure can affect how seals separate and move.
Adhesion and overlap
Tacky surfaces or static can create doubles that need controlled separation and verification.
Deformation
The presentation and gripper should not stretch, crease or permanently distort the part.
Cleanliness
Contact surfaces, coatings and cleaning access may be critical for medical, food or fluid-sealing applications.
Project definition
Information needed for an accurate recommendation.
The proposed method is selected from the actual component, accepted presentation and downstream process—not from a generic rate claim.
| Material and hardness | Elastomer type, Shore hardness, surface treatment, lubrication and cleanliness requirements. |
|---|---|
| Dimensions | Outside and inside diameters, section, flatness, free-state shape and tolerance range. |
| Incoming condition | Loose, bagged, stacked, oiled, powder-treated or compressed during storage. |
| Required presentation | Flat, centred, on edge, on a mandrel, in a nest or accessible to robot tooling. |
| Inspection | Single/double detection, dimensional presence, orientation and visible defect checks. |
| Acceptance | Representative batches across environmental and surface-condition variation. |
Evidence before approval
Send samples in the condition they reach production.
Clean laboratory samples may behave differently from warm, oily, static or compressed production parts. The trial should include the expected packaging and storage condition.
Common questions
O-ring and seal feeder questions.
Can O-rings be fed in a vibratory bowl?
Some can, particularly where size and material give stable movement, but flexible or tacky rings may suit a conveyor, magazine or vision-guided platform better.
How are double O-rings detected?
Detection may use mechanical separation, height sensing, vision, vacuum response or a combination depending on size and presentation.
Can lubricated seals be fed automatically?
Potentially. Lubrication changes friction and contamination control, so the actual production condition must be tested.
Can different seal sizes run on one system?
Flexible or change-part concepts may cover a family, but the separation method, pick accessibility and recipe controls must be verified for each format.
