Spare Parts & Components
Components for every line type we supply, matched by drawing, sample or model number, with replacement intervals and installation guidance attached.
- All line types
- Built to OEM standard
- Drawing, sample or model number
- Replacement intervals included
Parts as part of the line
A single worn component can stop a line for days. Ordering from the original equipment maker can mean a long lead time, while a part made without the original specification often fails early or damages the equipment around it.
Our spare parts service works from the same technical basis as the line scope: the drawing, the material, the heat treatment and the duty the part actually sees. That is what makes a replacement behave like the part it replaces.
Technical matching
Specification and material recommended against the line model and operating conditions.
Long-term supply
Support continues for lines that are no longer covered by their original maker.
Built to standard
Critical parts made to the original drawing, with material and hardness recorded.
Guidance attached
Installation advice and replacement intervals supplied with the part, not just the part.

Cut-to-length and slitting line parts

How to order
Two routes cover most requests: manufacture from a drawing or sample, or supply a standard part from the model number. The first fits worn mechanical parts; the second fits electrical, hydraulic and bearing items.
- Nameplate, drawing or a clear photograph with a size reference all work as identification
- Equipment model and parameters are enough for us to check the original configuration
- Old parts can be sent for reverse engineering when no drawing exists
Custom manufacture from drawing or sample
| Step | Action |
|---|---|
| 1 | Send the drawing (PDF or DWG), a physical sample, or dimensioned photographs |
| 2 | Engineers confirm dimensions, material and heat treatment, then quote |
| 3 | Production, typically 15 - 60 days depending on complexity |
| 4 | Inspection against the drawing, with a report issued |
| 5 | Packaging and shipment to the address you nominate |
Order by model number
| Step | Action |
|---|---|
| 1 | Send the part model or a nameplate photograph with brand and specification |
| 2 | We check stock or supplier availability and confirm the quotation |
| 3 | Standard parts usually ship within a few days of confirmation |

Questions
Questions we hear on this line
How do I identify the part I need?
A nameplate photograph, the OEM drawing, a dimensioned photo of the old part, or the equipment model and parameters are all enough to start. Where no drawing exists, the old part can be sent for reverse engineering.
Can a manufactured part match the original?
Critical parts are made to the original drawing and standard, with material, heat treatment, precision and hardness recorded. The inspection method is agreed before production, not after.
What warranty applies to spare parts?
Warranty is set by part category and stated in the quotation, covering quality-related failures rather than damage from installation or operation. Terms for rolls and air knives are agreed case by case.
Is there a minimum order quantity?
Standard parts can be ordered as single pieces. Custom-made parts usually start at two to four pieces depending on the process and material.
Which brands can you supply?
Mechanical parts are manufactured to the original standard and marked accordingly. Electrical, hydraulic and bearing items come from the named brands or agreed equivalents, and client-specified brands can be quoted on request.
