Roll Cassettes for Scale Breakers
The roll cassette supports the working roll and intermediate roll inside a scale breaker so bending and deformation stay minimal. Because the roll box is the core of the machine, its precision decides the characteristics and quality of the sheet or coil produced.
- Dimensional tolerance within ±0.05 mm
- High strength alloy steel construction
- Premium load bearing units rated for dynamic load
- Optimised roller alignment system
Key Benefits
The core value of a well built cassette.
Stable And Reliable Processing
Consistent geometry keeps the scale breaking process stable and reliable from coil to coil.
Dimensional Accuracy And Surface Quality
Optimised roller alignment maintains stable product geometry, giving uniform thickness distribution and better surface quality.
Downtime Reduced
Durable construction reduces the unplanned stops that come from cassette wear and roll deflection.
Where It Is Used
Where cassettes are fitted.
- Scale breaker machines on pickling lines
- Tension balancing machine structures
- Wide strip preparation sections
- Continuous cold rolled strip processing
Who It Is For
- Pickling line maintenance teams
- Plants rotating spare cassettes for service
- Rebuild shops overhauling scale breakers
- Buyers replacing cassettes with inconsistent geometry
Problems It Solves
- Bending and deformation of working and intermediate rolls
- Thickness variation across the strip width
- Unplanned downtime from cassette wear
- Geometry differences between replacement cassettes
Technical Features
Construction and tolerance.
CNC Machining And Robotic Assembly
Precision CNC machining with robotic assembly guarantees consistent geometric parameters within 0.05 mm.
High Strength Alloy Steel
The cassette is constructed from high strength alloy steel with premium load bearing units rated for dynamic load.
Roller Alignment System
An optimised alignment system holds product geometry stable through continuous operation.

Manufacturing Process
Machine Data Review
Cassette envelope, roll count and interfaces are confirmed against your scale breaker.
CNC Machining
The cassette body is machined so geometry stays inside the 0.05 mm band.
Roll And Bearing Assembly
Rolls and bearing units are fitted and alignment set.
Inspection And Records
Alignment and dimensional records accompany the cassette.
Quality Control
- Geometric inspection within ±0.05 mm
- Bearing unit verification
- Alignment measurement on the assembled cassette
- Material certificate for the alloy steel
Customization Options
- Cassette geometry to your scale breaker
- Roll count and diameter as required
- Bearing selection for the dynamic load
- Spare cassettes for rotating maintenance
Use Guide
- Rotate a spare cassette during service so the line restarts sooner
- Check alignment against the as built record after rebuild
- Replace bearing units on schedule for your load
- Clean and dry cassettes removed from acid line areas
How It Compares
Cassette sourcing options.
| Hand assembled cassettes | Robotic assembly with CNC machining repeats geometry within 0.05 mm across every unit. |
|---|---|
| Standard steel frames | High strength alloy steel with dynamic load rated bearings suits continuous scale breaking duty. |
| Repairing in place | An exchange cassette moves the rebuild off the critical path of the shutdown. |

What tolerance do you achieve?
Geometric parameters are held within 0.05 mm through precision CNC machining and robotic assembly.
What is the cassette built from?
High strength alloy steel with premium load bearing units rated for dynamic load.
How does the cassette affect product quality?
It supports the working and intermediate rolls to minimise bending and deformation, which directly affects thickness distribution and surface quality.
Can you build to our existing scale breaker?
Yes. Send the cassette drawing or detailed photos with dimensions and we produce to match.
Do you supply rolls and bearings separately?
Yes, rolls and bearing units for the cassettes we build are available as spares.
What is needed to quote?
