At PROEXPORT, we manufacture new dryer rolls and refurbish worn paper machine dryer cylinders. We combine hard chrome plating, machining, journal inspection, dynamic balancing and preparation for transport.
manufacture of new dryer rolls according to technical documentation or a supplied sample,
refurbishment of the working surface, journals and mechanical components,
diameters up to 600 mm, lengths up to 6,000 mm, and weights up to 2,500 kg.
Please upload a drawing, photos, or the basic specifications of the roller.
At PROEXPORT, you can order new dryer rolls as well as comprehensive refurbishment of worn paper machine rolls. We carry out the agreed scope of work: from technical assessment, hard chrome plating and machining through to dynamic balancing and preparation for transport.
We manufacture new dryer rolls in accordance with the customer’s technical documentation or based on a supplied sample.
We refurbish worn rolls, covering the working surface, journals, bearings and other components requiring repair.
We perform hard chrome plating on external and internal surfaces and then carry out the required finishing operations.
After applying the coating, we grind and polish the working surface and hone it where required.
As part of the refurbishment, we can inspect, repair or replace worn journals and bearings.
The finished roller undergoes dynamic balancing and can be prepared for domestic or international transport.
Please send us a drawing, photos, or a description of the roller—we will assess the scope of work involved.
We manufacture dryer rolls in accordance with the customer’s technical documentation and the requirements of the specific paper machine. The values below represent the range most commonly supplied.
| Body | steel |
|---|---|
| Working-Surface Coating | electroplated hard chrome coating |
| Maximum diameter | up to 600 mm |
| Maximum length | up to 6,000 mm |
| Maximum weight | up to 2,500 kg |
| Surface roughness after machining | Ra 0.08–0.16 |
| Typical thickness of a chrome coating | approx. 100 µm, to be determined with the customer |
| Finishing | grinding, polishing, honing |
| Runout | up to 0.02 mm, with requirements in accordance with the documentation |
| Custom Designs | including internal heating chambers, following an analysis of the documentation |
We confirm the final tolerances, machining range, and manufacturing parameters after analyzing the technical drawing, the condition of the cylinder, or the provided sample.
Dryer roll refurbishment involves more than restoring the hard chrome coating. At PROEXPORT, we assess the entire component: the working surface, journals, bearing seats and the mechanical work required to prepare the roll for further service.
We inspect the working surface, roll body, journals, bearing seats and mechanical components.
Depending on wear, we inspect, repair or replace the journals and bearing contact areas.
Refurbishment may include bearing replacement and inspection of the components responsible for correct roll operation.
We restore the working surface by applying a new hard chrome coating in accordance with the agreed scope of work.
After chrome plating, we perform finishing operations, including grinding, polishing, and, if necessary, honing.
After refurbishment, the roll undergoes quality inspection and dynamic balancing before preparation for installation.
Please send us photos, documentation, or a description of the damage—we will assess the extent to which the item can be restored.
For a worn dryer roll, the key question is whether it is suitable for refurbishment or whether manufacturing a new roll is the safer option. At PROEXPORT, we assess the technical condition first and only then recommend the scope of work.
Not sure which option to choose? Send the documentation, photos or the worn roll. We will assess its condition and advise whether refurbishment or manufacture of a new component is the better option.
The manufacture or refurbishment of a dryer roll starts with an assessment of the documentation, photos or the supplied component. This allows us to propose a scope of work matched to the actual condition of the roll and the requirements of the paper machine.
Please send the technical documentation, drawings, photos, or basic specifications for the roller.
We inspect the working surface, roll body, journals, bearing seats and mechanical components.
We present the recommended scope of production or refurbishment and explain the rationale behind it.
We perform the agreed-upon work: chrome plating, machining, mechanical repairs, polishing, or honing.
Once the work is complete, the roller undergoes a quality inspection and dynamic balancing.
We prepare the finished roll for shipment based on its dimensions, weight, and shipping requirements.
A drawing, photos, or basic specifications of the roller are sufficient to prepare a preliminary assessment.
When ordering a new roller or planning a refurbishment, the most common questions concern documentation, the scope of work, tolerances, chrome plating, and preparing the component for shipping. Below, we’ve compiled the most important points to clarify before sending an inquiry.
For dryer rolls, the quality of the hard chrome coating is only one consideration. The entire component matters: the body, journals, bearings, runout, balancing and preparation for installation. That is why PROEXPORT manages the agreed scope of work as one process rather than a series of separate manufacturing operations.
The customer does not need to arrange for chrome plating, journal repairs, bearing replacements, balancing, and transportation separately.
We can manufacture a new drying cylinder or refurbish an existing cylinder, provided its technical condition allows it.
We first assess the documentation, photos or the roll itself and only then propose the scope of manufacture or refurbishment.
We manufacture rollers in accordance with the customer's specifications. In confirmed projects, the runout achieved was up to 0.02 mm.
We prepare the rolls for transport based on their dimensions, weight, and delivery requirements.
Send us a drawing, photos, or a description of the problem—we'll get back to you with a recommended scope of work.
