Roller covering in
rubber and polyurethane

Soremag covers, refurbishes and finishes your industrial rollers in rubber or polyurethane — from material selection to precision finishing, in-house.

What is roller covering?

Roll covering means applying a layer of rubber or polyurethane over a steel core, then machining it to the exact diameter, profile and finish your application requires.

Polyurethane or rubber for a roller: which one should you choose?

The right method: start from the

limiting factor
at your position. If abrasion, load or cutting is what kills your rollers, polyurethane is often the right starting point. If it is grip, damping, gentle contact or a specific chemical constraint, then rubber — provided you pick the right family. No material is “better” everywhere: only the one whose trade-offs match your speed, your temperature, your chemistry and your finish. Here are the strengths of each.

Rubber Rollers

Rubber “works” with the material: it deflects under load then returns to shape, creating a stable contact footprint. You choose it when grip, damping or a specific chemical constraint comes first. Everything is decided by the compound and the Shore A hardness, matched to your application.

Polyurethane Rollers

Cast polyurethane takes over as soon as abrasion, load or cutting becomes the limiting factor: at equal durometer, it carries more and resists cutting better, often with a much longer service life. Available from soft to very hard (Shore A to Shore D). Its limits: high heat and prolonged moisture (ester formulations).

Why cover a roller in rubber or polyurethane?

In a plant, a roller is almost never “just a cylinder that turns.” Here is what matters, topic by topic.

A roller can drive a material, press a product, guide a web, absorb an impact, apply pressure, protect a surface or resist abrasion. The cover acts as an

engineered layer
between the metal roller and the product in contact — so that it
works better, lasts longer and suits its environment
, instead of just making it look good.

Le rôle d'un recouvrement+

A steel or aluminum roller is strong and accurate, but its surface does not always behave the way you need: too hard, too slippery, too aggressive or a poor match for certain conditions. We keep the metal core and adapt the outside surface to the real duty. A cover can:

  • increase friction and grip;
  • protect the product being conveyed or processed;
  • absorb vibration and impact;
  • improve the drive of a web, a film, a sheet or a material;
  • reduce roller wear;
  • resist certain chemicals, oils, solvents or wet environments;
  • control the pressure between two rollers;
  • improve the finish quality of the final product.

That is what turns a plain roller into a

performance component
— with a direct impact on productivity, equipment life and production quality.

Caoutchouc ou polyuréthane : comment trancher+

A

rubber
is often chosen for flexibility, grip, cushioning and work under pressure (pull rollers, nip rollers, drive, guiding, applicators).
polyurethane
is chosen for its excellent resistance to wear, abrasion, cutting and load in demanding conditions. There is no single right answer: the right choice depends on the application.

What to look at:

  • the product in contact with the roller;
  • the rotating speed and the applied load;
  • the operating temperature;
  • the presence of water, oil, solvents or chemicals;
  • the level of abrasion;
  • the durometer and surface finish you are after;
  • the mechanical tolerances and the production environment.

For the detail compound by compound: see rubber rollers or compare polyester and polyether polyurethane further down this page.

Reconnaître un rouleau à recouvrir+

A worn roller can keep turning while no longer doing its job — that is often where production losses start. Common signs: loss of grip, web slippage, abnormal vibration, uneven wear, cracking or hardening of the cover, marks on the product, diameter out of tolerance, delamination.

See the full troubleshooting guide →

Un bon recouvrement, c'est un ensemble complet+

Material choice matters, but it is not the only factor. Roller preparation, grit blasting, the bonding system, the formulation, vulcanization or casting, final machining and quality control all have a direct impact on performance. A cover has to be designed as a whole:

metal roll body + surface preparation + bonding system + material + durometer + machining + surface finish + final inspection

Neglect a single element and the roller can wear out early, debond, vibrate or fall short of the expected performance. That is why it pays to work with a team that understands the materials, the mechanics of the roller and the industrial application.

In short:
we cover a roller to match its surface to a specific job — improve grip, protect the product, reduce wear, absorb impact, resist abrasion, control pressure and extend service life. Well chosen and well executed, the cover makes the roller more reliable and longer-lasting: less downtime, less rework, better quality and better returns.

Rubber: choosing the right compound

From natural rubber to Viton, every family has its strengths. Identify the dominant resistance you need, then the compound that delivers it.

Manchons interchangeables

Do you run sleeves?

Soremag covers, rebuilds and precision-machines the interchangeable sleeves that run on applicator, printing, laminating and transfer rollers.

Your main shaft stays on the machine. With our own set of service shafts and mandrels, sized for a range of sleeve diameters, we cover and grind without tying up your shaft. The sleeve travels on its own: less handling, less freight, and the line restarts sooner.

What the service covers +

Stripping the old cover, preparing the body, applying the new elastomer, remachining, precision grinding, profiling, grooving and final inspection. Durometer and surface finish are chosen for the application, not carried over from a standard.

Materials available +

A full range of rubbers and polyurethanes, silicones, foams and other specialty materials. The choice follows the fluid being applied, the temperature, the pressure and the finish you need — the same criteria as a solid roller.

Where they run +

Applying dye, paint, varnish, adhesive or other coatings; wood finishing; printing; flexible packaging; laminating and converting film, paper or industrial sheet.

Polyurethane: ester or ether

Not all polyurethanes are equal. The choice comes down mainly to two base families — ester and ether — depending on whether you want pure mechanical performance or resistance to moisture.

Polyester polyurethane

Maximum mechanical performance

Built on ester polyols, it is the best in abrasion, in cut resistance and under heavy load, with good resistance to oils and hydrocarbons. Its Achilles heel is

hydrolysis
: in hot and humid or immersed service, the ester bonds break down, the cover softens and then falls apart. Reserve it for environments that stay
dry
. Typical service range ≈ −30 to 80 °C (indicative).

Polyether polyurethane

Water & cold resistance

Built on ether polyols, whose bonds resist hydrolysis: it is the choice as soon as there is water, steam, prolonged moisture or cold (better flexibility at low temperature, good rebound resilience, good resistance to microbes and mold). The trade-off: abrasion and load capacity slightly behind ester — a gap the right formulation and the right durometer close.

EsterpolyesterEntraînement haute charge · Abrasion sévère · Idlers · Nip durs
ÉtherpolyétherMilieu humide / eau · Basses températures · Lavage · Applications immergées

Indicative ratings (out of 5), based on the general properties of cast polyurethanes. The cover durometer, the cure system and the formulation shift these trade-offs. Soremag also develops dedicated formulations (e.g. PolySorNip for nip rollers).

Drawings lost? Material unknown? We rebuild it all.

Lost your original drawings? Your roller has a special formulation and you no longer know whether it is XNBR, SBR or something else? No panic: through

reverse engineering
, we start from your existing part and rebuild everything.

Real parts received at the shop: worn, cracked or debonded, often with no original drawings — we start from the part and rebuild everything.

1

Dimensional takeoff & drawing

We measure your roller and redraw it completely: dimensions, profile, target durometer and tolerances.

2

Laboratory material analysis

The existing cover is analyzed in the lab to identify its family and its properties — even with no documentation at all.

3

Faithful reproduction (or improved)

We reproduce the right material, the right durometer and the right finish for an identical roller — or an optimized one if your conditions have changed.

The job of the roller drives the cover

Driving, nipping, coating, squeezing, spreading, cooling: every position on a production line sets its own durometer, its profile, its surface finish and its groove pattern. A nip roller and an applicator roller can carry the same material and have nothing else in common. So we cover for the work the part has to do, not for a catalog category.

Circular economy: refurbish instead of buying new

Bringing an existing core back to life usually costs less than buying new, cuts the carbon footprint tied to manufacturing a complete part and shortens your supply lead times. A cheaper, greener and often faster choice.

Why send your rollers to Soremag

From the material to the part back in service — precision, balancing and traceability controlled in-house.

In-house precision grinding

Precision grinding to the required durometer, tolerance and surface finish, with no subcontracting.

Dynamic Balancing

Roller balancing to eliminate vibration and marking at high speed.

Retrofit & reverse engineering

Covering built from the old roller or from a sample, even without a drawing.

Laboratory validation + chemical engineer

The material and the durometer are validated in the lab, with traceability on every part.

Industries served

A material and a finish matched to the constraints of each industry.

Questions about roller covering

Can you cover a roller without the original drawing? +

Yes. Through reverse engineering, we reproduce the dimensions, the durometer and the profile of your roller from the old roller, a part or a simple sample, even with no drawing. If needed, we also adapt the material or the finish to the current requirements of your equipment.

How long does a cover last and what is the lead time? +

Service life and lead time depend on the type of cover, the durometer and the application. We offer pickup and delivery in Laval and Montreal, as well as service in Quebec, Ontario and the Maritimes, with emergency intervention available to cut your downtime.

Which Shore A hardness should I choose for my roller? +

The durometer is set to your application: load, speed, pressure, deflection, the grip you need and the environment. We recommend the material, durometer and surface finish package best suited to your process. Our Material Selection Guide details the trade-offs.

What information do you need for a quote? +

Ideally: the roller dimensions, the target durometer, the product in contact, the temperature, the speed, the load, the environment (dry, wet or oily) and the problem you are seeing. With that, we recommend the right material, durometer and finish. If needed, we also work from your old roller or from a sample.

What roller diameter and length can you cover? +

We run the largest multi-function CNC lathe linked to an in-house server, dedicated to rubber finishing, with a finished diameter up to

42 in. (1,066 mm)
and a length up to
20 ft. (6,096 mm)
. We cover small rollers just as well as very large parts.

Can the existing core be reused or do I need a new roller? +

In most cases, we take your existing roller and repair it and rebuild it to new — or simply resurface it if the core and the cover allow. Reusing the core cuts cost and lead time.

Do not let chance dictate your downtime.

Choosing the wrong material means risking early wear, quality rejects and costly downtime. Stop spending your budget on standard covers that do not hold up to your real conditions.

The verdict? There is no miracle material, only the right solution for YOUR equipment.

Stop guessing and let the Soremag specialists make the call. Tell us your worst production challenges (severe abrasion, extreme load, chemicals), and we will recommend

the right formulation
that will push up the service life of your rollers.
