Roll Cassettes for 1660 mm Scale Breakers
The roll cassette supports the working roll and intermediate roll and keeps bending and deformation to a minimum, so it directly sets the dimensional accuracy and surface quality of the sheet or coil coming off the line.
- For 1660 mm scale breaker machines
- Dimensional tolerance within ±0.05 mm
- High strength alloy steel equivalent to DIN 1.2344
- CNC machining with robotic assembly
Key Benefits
The three things a good cassette protects.
Process Stability
Holding roll positions stable is what keeps the scale breaking process repeatable from coil to coil.
Dimensional Accuracy And Surface Quality
Consistent geometric parameters give uniform thickness distribution and a clean surface across the finished material.
Less Downtime
A durable cassette reduces the unplanned stops that roll deflection and wear would otherwise cause.
Where It Is Used
Where the cassette runs.
- 1660 mm scale breaker machines
- Pickling line entry sections
- Wide cold rolled strip preparation
- Tension balancing machine structures
Who It Is For
- Pickling line maintenance teams
- Plants standardising cassettes across positions
- Rebuild shops servicing scale breakers
- Buyers replacing a cassette whose OEM is unavailable
Problems It Solves
- Bending and deformation of working and intermediate rolls
- Thickness and surface variation on finished coil
- Downtime from cassette related failures
- Inconsistent geometry between replacement cassettes
Technical Features
Manufacturing and materials.
Precision CNC And Robotic Assembly
Consistent geometric parameters are guaranteed with dimensional tolerances within 0.05 mm.
Optimised Roller Alignment
The alignment system maintains stable product geometry through continuous operation.
High Strength Alloy Construction
Built from high strength alloy steel equivalent to DIN 1.2344 with premium load bearing units rated for dynamic load.
Specifications
Cassette dimensions match your scale breaker. Manufacturing data is listed below.
| Machine Width | 1660 mm scale breaker |
|---|---|
| Dimensional Tolerance | Within ±0.05 mm |
| Material | High strength alloy steel equivalent to DIN 1.2344 |

Materials
- DIN 1.2344 equivalent alloy steel frame
- Premium dynamic load rated bearing units
- Hardened roll surfaces
Manufacturing Process
Drawing Confirmation
Cassette envelope, roll count and interface points are confirmed from your machine.
CNC Machining
Frames are machined so geometric parameters stay within the 0.05 mm band.
Roll And Bearing Fitting
Rolls and load bearing units are fitted and alignment set.
Final Inspection
Alignment and dimensional records are produced before packing.
Quality Control
- CNC dimensional inspection within ±0.05 mm
- Bearing unit load rating verification
- Roller alignment measurement on assembly
- Material certificate for the alloy grade
Customization Options
- Cassette geometry to your scale breaker
- Roll count and diameters as required
- Bearing selection for your dynamic load
- Spare cassettes for rotating stock
Use Guide
- Keep one cassette in rotation so service happens off line
- Check alignment records against the as built report
- Replace bearing units at the interval set for your load
- Clean acid residue from cassette surfaces after removal
How It Compares
Cassette sourcing options.
| Manually assembled cassettes | CNC machining with robotic assembly holds geometric parameters within 0.05 mm consistently between units. |
|---|---|
| Standard structural steel frames | DIN 1.2344 equivalent alloy resists the load and wear of continuous scale breaking. |
| Repairing a worn cassette | A new cassette restores alignment and bearing condition together rather than fixing one symptom. |
