Back Up Rolls for Leveling Machines Built on 20 Years of Component Focus
This roll line is the product of two decades spent refining one component. The back up roll supplies the rigidity behind the work rolls, and everything in the specification, from heat treatment depth to grinding class, exists to keep that rigidity stable through a long service life.
- Over 20 years of experience on this component
- Deep heat treatment and precision grinding
- Geometry in the 0.005 mm class
- Surface finish around 0.2 micron
Key Benefits
What two decades of process work delivers.
Stability Shift After Shift
Exceptional stability and repeatable precision mean the leveling line does not need re tuning between shifts.
Wear Resistance And Service Life
Deep heat treatment with precision grinding gives the wear resistance that modern steel rolling production demands.
Process Knowledge In The Product
Thousands of hours of process optimisation on this one component are reflected in the roll specification.
Where It Is Used
Lines that use them.
- Precision leveling lines in steel plants
- Coating line leveler cassettes
- Non ferrous strip leveling
- Cut to length line leveling sections
Who It Is For
- Plants where leveling stability is a delivery requirement
- Maintenance teams replacing worn back up rolls
- Machine builders specifying roll systems
- Buyers seeking a specialist rather than a general roll shop
Problems It Solves
- Leveling precision varying between shifts
- Back up roll wear transferring into work roll deflection
- Short roll life under modern rolling loads
- Inconsistent quality between roll suppliers
Technical Features
Specification points.
Deep Heat Treatment
Hardness is developed deep into the body so the roll survives repeated regrinding without losing support capability.
Precision Grinding To 0.005 mm Class
Geometric accuracy in the 0.005 mm class with a 0.2 micron finish keeps contact even along the barrel.
Specialist Component Focus
The design reflects continuous refinement of back up rolls specifically, not a general roll catalogue.

Manufacturing Process
Application Review
Machine type, cassette position and strip programme are reviewed with your drawing.
Turning
Roll bodies are turned with heat treatment allowance.
Deep Heat Treatment
Hardness is developed through the body for long regrind life.
Precision Grinding And Inspection
Rolls are ground to the 0.005 mm class and inspected before packing.
Quality Control
- Hardness and case depth verification
- Roundness and cylindricity measurement
- Surface finish inspection
- Runout check on journals
Customization Options
- Dimensions and journal detail to your machine
- Hardness specification for the strip programme
- Matched sets per cassette
- Repeat supply against an agreed drawing
Use Guide
- Change back up rolls as a set
- Suspect the back up side when flatness returns soon after a work roll change
- Regrind within the stated allowance
- Store and handle rolls so journals stay protected
How It Compares
Against general purpose roll supply.
| General roll shops | Two decades of focus on back up rolls specifically, with a documented hardness and grinding specification. |
|---|---|
| Shallow hardened rolls | Deep heat treatment supports more regrinds and a longer usable life. |
| Rolls without geometric records | Inspection records to the 0.005 mm class let you verify what you installed. |

How is this different from your other back up roll line?
It is the same component focus expressed as a long experience build, with deep heat treatment and 0.005 mm class grinding. We will advise which specification fits your machine and strip programme.
What accuracy do you grind to?
Geometry in the 0.005 mm class with surface finish around 0.2 micron.
Will they fit our existing cassette?
Yes, rolls are produced to your drawing or sample so they fit the existing housings and seats.
How long do they last?
Life depends on strip material, load and tonnage. Deep heat treatment and grinding accuracy are what extend it, and we can advise regrind intervals for your duty.
Can you supply repeat orders to the same drawing?
Yes, we keep the drawing on file so repeat sets are identical.
What do you need to quote?
Roll drawing or sample, machine type, line width, strip material and quantity per set.
