Holistic implementation
for special machine construction in paper machine engineering

Benefit from our expertise:

We produce complex components, assemblies and bills of materials from a single source – precisely and reliably.

Where does it pinch in everydayspecial machine construction?

Questions many paper machine builders are familiar with

Do you repeatedly experience quality defects or complaints with highly stressed screws, bolts or fasteners that cause downtime?
Do your maintenance staff have to reorder special parts at short notice because the original bill of materials was incomplete or incorrect?
Do missing test certificates, untraceable material batches or incomplete documentation delay the approval and commissioning of your machines?
Does rework or clarification with suppliers lead to project delays and tie up valuable capacity in design and quality assurance?

If you’re nodding here, it’s worth taking a look at Stahlberg.

Your added value – at a glance

High-strength, media-resistant and wear-resistant materials
We use quenched and tempered steels, duplex and super duplex steels as well as nickel and titanium alloys that offer maximum strength, corrosion resistance and toughness – ideal for the enormous compressive, tensile and vibration loads in paper machines.

Specialized coatings
Surface treatments such as hard chrome plating, phosphating, anodizing or electroplated coatings ensure longevity in humid, chemically aggressive environments and prevent premature wear.

Custom-made geometries
Exact manufacturing to drawing – from special dimensions to large-format parts over 3,000 mm. Maximum fitting accuracy ensures smooth integration into roll, bearing and drive systems.

Complete inspection procedures / documentation
All destructive and non-destructive tests (hardness, tensile test, crack testing, ultrasonic, X-ray) as well as geometric measurements are documented. Every part is traceable, archived and approved in accordance with standards – for complete security in audits and ongoing operation.

From idea to delivery – your project cycle

Avoid costly downtime – with our
seamless project cycle:

A breakdown caused by a single defective component not only slows down your production – it also leads to delays, rising costs and missed delivery dates. This is exactly where our project cycle comes in: as early as consulting & design, we define critical characteristics, in the bill of materials check we close gaps, and through comprehensive quality & documentation we verify every property before the part reaches your plant. This minimizes the risk of unplanned downtime and gives you the decisive edge over competitors who still work with standard solutions.

Step	Our contribution	Your benefit
Consulting & design	Materials expertise, advice on surface finishing	Certainty that part and process match
Bill of materials check	Preparation of complex bills of materials / packing lists	No more missing items
Manufacturing	State-of-the-art manufacturing methods for machining, forming and surface finishing	Parts exactly to your specifications
Quality & documentation	Inspection, inspection plans, certificates, traceability, archiving	Complete inspection of manufacturing results, full documentation and thus a reduction in your own inspection scope, lifelong archiving of quality records
Logistics	Just-in-time, consignment warehouse and framework agreements with short-notice shipping of stored goods	Fewer complaints in your own incoming goods department, less effort thanks to goods inspected by Stahlberg – and spare parts exactly where you need them.

Materials +processes –precisely combined

Well-functioning paper machines require a choice of materials and processes that permanently withstand extreme loads, wear and changing operating conditions – and it all comes down to precise execution.

Stahlberg implements your specifications exactly: components for rolls, bearings and drive elements, wear-resistant surfaces for wet and dry sections, tight tolerances – fully documented and traceable.

Material groups at a glance

Quenched and tempered & structural steels for highly dynamic loads
Creep-resistant and heat-resistant steels for extreme temperatures
Titanium alloys for maximum service life
Stainless steels & duplex for corrosion-critical areas
Non-ferrous metals (e.g. aluminum, copper, nickel and titanium) for special applications

Typical processes (as specified)

Heat treatment: hardening, quenching and tempering, induction hardening for roll and bearing parts
Surfaces: hard chrome plating, phosphating, anodizing, electroplated coatings for wear and corrosion protection
Machining & finishing: precision turning, milling, grinding, honing for exact fits and surface qualities

Product solutions at a glance – manufactured exactly to your specifications

Stahlberg does not supply off-the-shelf standard goods, but coordinates the custom manufacturing of all components relevant to paper machines – according to drawing, specification and bill of materials, with the right specialist manufacturers, fully monitored and documented.

Our range includes:

Fastening technology (special screws, nuts, washers – high-strength, documented)
Precision turned & milled parts (bearing housings, roll mounts, fastening elements)
Assemblies & assembly kits (screw connections, brackets, including sealing and fastening elements)
Pipe/valve components (connectors, reducers, couplings)
Peripherals & spare parts packages (defined surfaces, clean and documented execution for spare and wear parts)

Every item is produced to your specifications – with inspection plans, certificates, traceability and archiving, for maximum operational reliability in paper machine engineering.

Holisticprocurement instead of “parts Tetris”

Do you also need roll mounts, housing components, screw connections, seal packs or precisely manufactured spare parts so that your paper machine goes into operation reliably and on schedule?

For us, procuring even the smallest special items is a matter of course – and the complete, documented implementation of your bill of materials is the basis of our offer.

Stahlberg looks at your paper machine project as a whole: we coordinate all items – from high-strength screws and special bolts to assemblies and bearing housings to complete spare parts packages – documented, on schedule and ready for assembly. This helps you avoid delays, reorders and unnecessary coordination effort.

We implement holistically:

Special components (e.g. roll mounts, bearing housings, dowel pins, special screws)
Complex assemblies (assembly kits including screw connections, sealing and fastening elements)
Multi-part bills of materials (with defined tolerances, inspection and documentation requirements)

"No compromises on quality: with us, you’re on the safe side"

Your quality – inspected by us. Right from the start.

Less effort, less risk – with your individual quality assurance agreement with Stahlberg. Complex bills of materials, safety-relevant components, tight tolerances – wherever every detail matters, quality is no coincidence. But ensuring this quality in-house ties up valuable time, resources and personnel.

Stahlberg takes a different approach:
With an individual quality assurance agreement, you hand over a large part of your inspection responsibility to our experienced hands – including all documentation, inspection reports and approvals according to current standards.

Reduction of internal inspection effort in incoming goods
Minimization of complaints through continuous quality controls
Access to pre-inspected stock from consignment inventory
Traceability for every component
Security toward your customers and in audits
Planning reliability through clear processes and documented standards
