Wear Parts & Planned Replacement
The recurring component families across all machine systems — what makes them wear, and how to replace them on a plan instead of on a breakdown.
Wear-part families
Typical Wear Parts
The exact items and wear limits are defined per machine in your Path Pack documentation. These families recur across configurations.
| Component | Affects | Early signals |
|---|---|---|
| Sealing jaw faces & elastic elements | Seal quality | Weak or uneven seals, face scoring |
| Cutting blades & anvils | Cut quality | Ragged cuts, incomplete cuts |
| Feed rollers & infeed belts | Product transport | Slipping, spacing drift, length variation |
| Drive & timing belts | Motion transfer | Tension loss, glazing, cracks |
| Guide contact surfaces & wear strips | Product positioning | Wear grooves, misalignment |
| Filters (air preparation, cabinet) | Air and cabinet quality | Saturation, pressure drop |
Planning Replacement
Two criteria — whichever comes first.
- The manual's wear limit: replace when the documented limit is reached, per your machine's spare parts and maintenance documentation.
- Your quality trends: weekly seal appearance, cut quality and spacing records reveal wear before faults — see Maintenance Records.
- Stock the families your consumption log shows consuming fastest; plan long-lead assemblies on a calendar instead of waiting for failure.
- Log every replacement with running hours and film used — the log becomes next year's stocking list.
Technical Note
No universal intervals are published here — wear depends on product, film and duty cycle, and Path Pack defines limits per machine. Short answers: Which parts are considered wear parts?
Ordering Wear Parts
Identification first — then quotation.
- Machine model and serial number
- Part number, where marked or listed
- Quantity and photos of the part installed
See Before Requesting a Part for the full checklist, or browse parts by system: Sealing · Cutting · Feeding · Motion.
