Chrome Plated Work Rolls From 16 mm to 68 mm With Matched Back Up Rolls
This range covers work rolls from 16 mm to 68 mm supplied as a system with chrome plated back up rolls for tension balancing. Pairing the two means wear rates match, so the whole roll system reaches its service life together instead of one part forcing an early change.
- Work roll diameter 16-68 mm
- Supplied with chrome plated back up rolls
- Electroplated chrome surface at HV 800-1000
- Lower friction coefficient against the strip
Key Benefits
Why the pairing matters.
System Durability
Work rolls systematically paired with chrome plated back up rolls deliver durability and operational stability in demanding strip processing.
Hardness With Lower Friction
Electroplated chrome raises surface hardness to HV 800-1000 while reducing the coefficient of friction against the strip.
Longer Life For Roll And Strip
The combination extends service life of both the roll system and the quality of the processed strip material.
Where It Is Used
Applications.
- Tension balancing roll systems
- Multi roll leveler cassettes
- Continuous high load strip processing
- Modern metallurgical production lines
Who It Is For
- Plants running tension balancing machines
- Maintenance stores ordering roll systems
- Machine builders assembling roll cassettes
- Buyers replacing rolls that wear unevenly
Problems It Solves
- Work rolls and back up rolls wearing at different rates
- High friction marking the strip surface
- Short service life under continuous high load
- Sourcing a specific diameter inside the 16-68 mm band
Technical Features
Roll system specification.
Full Diameter Coverage
Precision engineered work rolls cover the comprehensive diameter range from 16 mm to 68 mm.
Chrome Plated Back Up Rolls
Back up rolls are chrome plated as well, so the whole contact chain resists wear.
HV 800-1000 Surface
Electroplated chrome surface treatment brings roll hardness to HV 800-1000 with a lower friction coefficient.
Specifications
Roll dimensions and plating are produced to your cassette drawing.
| Work Roll Diameter | 16-68 mm |
|---|---|
| Surface Hardness After Plating | HV 800-1000 |
| Back Up Rolls | Chrome plated, supplied as a matched system |
| Surface Roughness | 0.1 micron class |
| Plating Reference | Coating thickness up to around 0.3 mm depending on the build |
| Duty | Continuous high load strip processing |
Materials
- Alloy steel roll bodies
- Electroplated chrome surfaces on work and back up rolls
- Ground journals
Manufacturing Process
System Review
Work roll and back up roll dimensions are taken together so the system is matched.
Machining
Roll bodies are turned to size with plating allowance.
Heat Treatment And Grinding
Bodies are treated and ground before plating.
Electroplating And Finish Grinding
Chrome is deposited and finish ground to the target diameter and hardness condition.
Quality Control
- Surface hardness testing after plating
- Diameter and straightness inspection
- Roughness measurement in the 0.1 micron class
- Matched set verification before packing
Customization Options
- Any diameter within 16-68 mm
- Matched back up roll dimensions
- Plating thickness by strip material
- Complete cassette sets
Use Guide
- Replace work and back up rolls together to keep wear matched
- Check strip surface for marks as an early wear signal
- Regrind before chrome wears through
- Keep a matched spare set for each cassette type
How It Compares
System supply against single roll replacement.
| Replacing work rolls only | Matching work and back up rolls keeps wear balanced so the system lasts longer as a whole. |
|---|---|
| Unplated back up rolls | Chrome plating on both roll types resists wear through the entire contact chain. |
| Standard catalogue diameters | Any diameter within the 16-68 mm band can be produced to your cassette drawing. |

Read MoreChrome Plated Work Rolls 16-68 mm FAQ
Are the back up rolls included?
The rolls are designed as a system with chrome plated back up rolls. We can supply work rolls alone or the matched system depending on your maintenance plan.
What surface hardness is achieved?
Electroplated chrome treatment gives HV 800-1000 surface hardness while reducing the coefficient of friction.
What diameters can you produce?
Work rolls from 16 mm to 68 mm, produced to your cassette drawing.
How does this extend strip quality?
Lower friction and a harder surface reduce pickup and marking, so surface quality holds through the campaign.
Can we order a spare matched set?
Yes, many plants keep one matched set per cassette type so a change can be completed in a single shutdown.
What do you need to quote?
Work roll and back up roll dimensions or drawings, cassette model, strip material and quantity.
