Roller and Wheel Diagnostics

A recurring problem? We do not “make the same thing again”. We fix the root cause.

When a roller wears out too fast, when a wheel turns unstable, or when a cast part always breaks in the same place, making an identical replacement rarely settles the real problem. At Soremag, we do application diagnostics and industrial troubleshooting to stabilize the performance of your covered rollers (rubber and polyurethane), polyurethane wheels and cast polyurethane parts. The goal: cut your downtime, reduce scrap, improve the quality of the finished product and turn a recurring failure into a lasting solution.

The problems we see most often (and why they happen)

Premature wear / abrasion / tear-out

Wear that is “too fast” despite a “logical” durometer
Tear-out, cuts, chunking, tears
Wear at the ends (edge wear)

Quality problems (marking / lines / defects)

Marking, lines, surface defects, unwanted texture
Build-up, insufficient release
Unstable traction (slippage), product transfer

Debonding / adhesion

Cover debonding from the core
Failure linked to the preparation, the bonding agents, the cycling
Effect of chemistry, heat or cleaning

Vibration / instability / geometry

Vibration, chatter, runout
Poor pressure profile
Need for a crown, a taper or a special profile
Inadequate grooving and finish

From a “fragile roller” to a part that is stable in production

The answer is almost always a combination of six elements, adjusted together:

MatériauEPDM, nitrile, silicone, hypalon, polyuréthane ester/éther

DuretéShore adaptée à l'application réelle

Fini de surfaceLisse, mat, micro-texturé, poli

GéométrieDroit, bombé/crown, conique, profil spécial

Rainures / groovingDiamant, longitudinal, hélicoïdal, multi-entrées

Base mécaniqueMandrin/core, portées de roulement, alignement, équilibrage, runout

Describe how the roller behaves in service — that is where we find the right combination.

Define the symptom

What you observe, when, and the impact.

Describe the whole application

Machine, product, speeds, load/pressure, temperature, environment, cycles, stoppages.

Document the cleaning

Products, method, frequency, contact time, rinsing/drying, recent changes.

Analyze the chemistry & the abrasion

Choose the strategy

Material + durometer + finish + geometry/crown + grooving, + dual hardness if needed.

Manufacture / refurbish

Dimensional inspection, finish validation, consistency.

Stabilize

Maintenance + a preventive replacement plan.

Pulp and paper / Board

Maintenance manager

Problème : usure prématurée + perte de performance rapide → interventions répétées.
Intervention : visite sur site + analyse application/nettoyage + matériau optimisé + dureté revue.
Résultat : performance stabilisée + moins d'interventions non planifiées.

“We were caught in a loop: the roller lasted about three weeks, then performance dropped and we were back to replacing it. Trial after trial, our supplier had changed the material several times and ended up telling us: "raise the hardness, it will hold up". Soremag went about it properly: they came on site, looked at how it works, asked questions about the pressure, the speed, and above all the cleaning. Their recommendation was the opposite: a better-suited material and a lower hardness. Since then, we have taken back control. Performance stays stable, we plan our interventions instead of chasing downtime, and we finally have consistency. (translated from French)”

Solution appliquée : matériau adapté à l'usure + duro ajusté (à la baisse) + validation en service.

Mining / Optimization

Optimization Manager

Problème : roues critiques → remplacements imprévus + arrêts coûteux.
Intervention : échanges de données + 3 options en polyuréthane + optimisation géométrie + rainure.
Résultat : durée de vie prolongée + remplacement planifié + remise à neuf intégrée.

“We had always bought from the OEM, and it was always the same story: it would end up letting go at the wrong moment. We wanted to get out of "emergency" mode. With Soremag, we worked on it like a project: documents, operating conditions, constraints, and several technical exchanges. They proposed three polyurethane solutions — not a single "miracle recipe". The best one was then optimized with a different geometry and a groove on the diameter. That is where we saw the difference in stability. Today, we replace preventively rather than in an emergency, and the refurbishment makes the investment pay back very quickly. (translated from French)”

Solution appliquée : polyuréthane (option optimisée) + géométrie ajustée + rainure sur diamètre + programme de remise à neuf.

FAQ — your frequently asked questions (and our answers)

How do you determine the right material (rubber or polyurethane)? +

We start from the real application: chemistry in contact, abrasion, temperature, speed, pressure, cycles and cleaning. Then we adjust material + durometer + finish + geometry (crown) + grooving.

Does “harder” mean “longer lasting”? +

Not necessarily. A durometer that is too high can create slippage, marking, vibration or an inadequate pressure footprint. We aim for the solution that holds up in your real application.

Why does a roller mark the product? +

Often: pressure + profile (crown) + finish + vibration/runout. The fix can be a finish, a profile, a groove… or a mechanical correction upstream.

Why does build-up increase after a change in cleaning? +

Some products leave a film, change the friction or attack the surfaces. We want the whole routine (products + frequency + contact time), then we adapt the material and the finish.

Do you do retrofit / reverse engineering? +

Yes. We can reproduce a part, but our strength is above all to improve it: stability, service life, traction, resistance, and fewer defects.

What are the core, the journals and the shaft? +

Core: the internal base the cover is applied to. Bearing journals: the machined zones where the bearings sit. Shaft: structure and transmission of loads. A mechanical base that is out of tolerance can ruin the performance of the best cover.
