Work Roll for Tension Leveller Cassettes in 30 40 and 70 mm
The work roll is the part of a leveller cassette that contacts the strip and therefore sets flatness and surface quality. These rolls are produced in the industry standard diameters of Ø30 mm, Ø40 mm and Ø70 mm so they fit the majority of cassette designs without modification.
- Industry standard diameters Ø30, Ø40 and Ø70 mm
- Surface hardness HRC 58-62 and above
- Deep hardened layer for indentation resistance
- Ground to micron level tolerances
Key Benefits
Why the roll set decides cassette performance.
Flatness Across Different Metals
The rolls are engineered to deliver flatness and surface quality across a range of metal strip materials rather than one grade.
Indentation Resistance
Specialised heat treatment gives HRC 58-62 and above with a deep hardened layer, which is what resists indentation under continuous load.
Drop In Fit
Standard diameters match most cassette designs, so the replacement does not require machine changes.
Where It Is Used
Applications.
- Tension leveller cassettes on strip processing lines
- Coating line levelling sections
- Cut to length line levellers
- Non ferrous strip levelling
Who It Is For
- Plants running standard diameter cassettes
- Maintenance stores ordering by roll diameter
- Machine builders assembling cassettes
- Buyers replacing rolls that indent or wear early
Problems It Solves
- Indentation marks on strip from soft rolls
- Flatness loss as roll geometry wears
- Long lead times for cassette spares
- Rolls that do not match the original cassette tolerance
Technical Features
Roll specification.
High Grade Alloy And Tool Steel
Rolls are manufactured from high grade alloy steel and advanced tool steels chosen for hardness and toughness.
HRC 58-62 With Deep Case
Specialised heat treatment gives surface hardness of HRC 58-62 and above with a deep hardened layer.
Micron Level Grinding
Each roll is ground to micron level tolerances so the set is consistent inside the cassette.
Specifications
Standard diameters are listed. Other diameters are produced to drawing.
| Standard Diameters | Ø30 mm, Ø40 mm, Ø70 mm |
|---|---|
| Surface Hardness | HRC 58-62 and above |
| Hardened Layer | Deep hardened layer for wear and indentation resistance |
| Material | High grade alloy steel and advanced tool steel |
| Grinding Tolerance | Micron level |
| Fit | Suits a wide range of cassette designs |
Materials
- High grade alloy steel
- Advanced tool steel for higher duty
- Optional surface treatment by application
Manufacturing Process
Size Confirmation
Diameter, barrel length and journal detail are taken from the cassette or the drawing.
Machining
The roll is turned with allowance for heat treatment and grinding.
Heat Treatment
The surface reaches HRC 58-62 and above with a deep case.
Precision Grinding
The roll is ground to micron level tolerances and inspected.
Quality Control
- Hardness testing on the barrel
- Micron level dimensional inspection
- Straightness and runout check
- Set matching before packing
Customization Options
- Diameters outside the standard three
- Barrel length and journal to your cassette
- Hardness specification for specific strip materials
- Sets marked by cassette position
Use Guide
- Change rolls as a complete set inside one cassette
- Check the cassette seats for wear during the change
- Order by diameter and barrel length, not by machine name alone
- Store rolls oiled and supported
How It Compares
Against other work roll options.
| Lower hardness rolls | HRC 58-62 with a deep case resists indentation that softer rolls pick up within weeks. |
|---|---|
| Rolls ground to coarse tolerance | Micron level grinding keeps every roll in the set within the cassette tolerance band. |
| Non standard diameters | Standard Ø30, Ø40 and Ø70 mm sizes can be stocked and fit most cassette designs directly. |

Read MoreWork Roll for Tension Leveller Cassettes FAQ
Which diameters do you produce as standard?
Ø30 mm, Ø40 mm and Ø70 mm. Other diameters are produced to drawing when your cassette needs them.
What hardness do the rolls reach?
HRC 58-62 and above, with a deep hardened layer from specialised heat treatment.
Which strip materials can they handle?
A range of metal strips including carbon steel, stainless steel and non ferrous materials, within your cassette capability.
How tight are the tolerances?
Rolls are ground to micron level tolerances so the set stays consistent inside the cassette.
Can you supply matched cassette sets?
Yes. Work rolls, intermediate rolls and back up rolls can be supplied together as a matched set.
What do you need to quote?
Diameter, barrel length, journal detail or a sample roll, quantity per set and annual usage.
