Roll Units for High Accuracy Tension Leveling Machines With 16 mm Work Rolls
A 16 mm work roll is slender enough to deflect under leveling load, and once it deflects output and strip surface quality both fall. These roll units support the work rolls and intermediate rolls so the small diameter geometry stays true across the strip width.
- Built for 16 mm diameter work rolls
- High surface hardness with uniform distribution
- Deep hardened layer with anti spalling performance
- Strong overload impact resistance
Key Benefits
Why support units decide what a small diameter cassette can do.
Deflection Prevented
The primary function is to support work rolls and intermediate rolls so 16 mm rolls do not deflect or deform under load.
Output Protected
Without stable support, roll deformation reduces production output and damages the surface quality of sheet and strip.
Suited To High Speed Lines
The combination of hardness, toughness and overload resistance fits high speed, large output, high precision leveling lines.
Where It Is Used
Where these units sit.
- High accuracy tension leveling machines
- Small diameter multi roll cassettes
- Thin gauge strip leveling lines
- Precision sheet finishing sections
Who It Is For
- Plants running 16 mm work roll cassettes
- Maintenance teams chasing flatness problems to the support side
- Equipment builders assembling high accuracy levelers
- Buyers replacing deformed roll units
Problems It Solves
- Deflection of slender 16 mm work rolls
- Surface quality damage caused by roll deformation
- Output loss when the cassette cannot hold geometry
- Spalling on support rolls after overload
Technical Features
Mechanical properties.
Uniform Hardness Over The Body
High surface hardness is distributed uniformly over the entire roll body rather than concentrated at the contact zone.
Balanced Neck And Barrel
Roll neck and barrel are balanced for strength and toughness, which is what resists overload impact.
Anti Spalling Surface
Reliable anti spalling performance keeps the support surface intact through repeated load cycles.

Manufacturing Process
Cassette Data Review
Roll count, spacing and unit dimensions are taken from drawing or sample.
Machining
Support roll bodies and unit frames are machined to position tolerance.
Heat Treatment
The deep hardened layer is built with uniform hardness across the body.
Assembly
Units are assembled, alignment checked and marked by position.
Quality Control
- Hardness and layer depth verification
- Position tolerance check on the assembled unit
- Runout measurement on support rolls
- Overload related surface inspection before packing
Customization Options
- Unit geometry for other work roll diameters
- Roll count and spacing to your cassette
- Plating specification per strip material
- Matched replacement sets per machine
Use Guide
- Replace units in complete rows so support is even
- Inspect for spalling whenever flatness drifts
- Keep bearings and seats clean during assembly
- Record which position each unit came from before removal
How It Compares
Against other support arrangements.
| Fewer larger support rolls | Dedicated roll units keep small diameter work rolls supported along the whole barrel instead of at a few points. |
|---|---|
| Standard hardness support rolls | Anti spalling performance and overload resistance survive the shock loads high speed lines produce. |
| Running deformed units | Replacing the unit restores geometry, which is what returns output and surface quality. |

Read MoreRoll Units for High Accuracy Tension Leveling With 16 mm Work Rolls FAQ
Why do 16 mm work rolls need dedicated units?
At that diameter the roll deflects under leveling load. Without stable support, deformation reduces output and damages the surface quality of the sheet or strip.
Can you supply units for other work roll diameters?
Yes. The same construction is produced for other diameters. Send the cassette drawing and we adapt the unit geometry.
What hardness do the support surfaces reach?
High surface hardness with uniform distribution over the roll body and a deep hardened layer, with anti spalling performance under repeated loading.
How do we know the units are worn?
Flatness drifts and marks appear on the strip even after a work roll change. That usually points to the support side.
Do you supply complete cassettes as well?
Yes, roll units, work rolls, intermediate rolls and cassettes are produced in the same shop.
What is needed for a quotation?
Cassette drawing or sample unit, work roll diameter, line width and quantity of units required.
Restore Your Cassette Geometry
Send the cassette drawing or a photo of the worn unit and our engineers quote a replacement set.
