Roll End Supports With Ceramic Bead Heads for Tension Leveller Cassettes
The roll end support sits on both sides of the roll cassette and restricts the axial movement of the intermediate roll and the work roll. The head is inlaid with ceramic beads, which is what lets the roll end turn against the support without galling.
- Size 29 by 51 mm
- Head inlaid with ceramic beads
- Assembled with bearings
- Fitted on both sides of the roll cassette
Key Benefits
What the ceramic head adds.
Axial Movement Controlled
The support restricts axial movement of the intermediate roll and work roll, keeping the roll set located as designed.
Low Friction Contact At The Head
Ceramic beads inlaid in the head handle the rotating contact at the roll end where a plain steel face would wear or gall.
Reliable Durable Structure
The structure is reliable and durable, with precise sizing so the assembly with bearings is correct.

How It Compares
Against a plain roll end sleeve.
| Plain roll end sleeve | The ceramic bead head handles rotating contact where a plain steel face would wear. |
|---|---|
| Re using worn supports | Worn supports let the roll drift axially, which changes the cassette geometry. |
| Improvised replacements | Precise sizing to drawing keeps the bearing assembly and roll location correct. |

Roll End Support With Ceramic Beads 29 by 51 mm FAQ
What does the roll end support do?
It is applied to both sides of the roll cassette in a tension leveller and restricts the axial movement of the intermediate roll and the work roll.
Why ceramic beads?
The head is inlaid with ceramic beads to handle the rotating contact at the roll end, which is where wear and galling would otherwise occur.
What size is supplied?
29 by 51 mm as standard, with other sizes produced to drawing or sample.
Is it supplied with bearings?
It is designed to be assembled with bearings. Tell us your bearing selection and we match the seat.
When should these be replaced?
During cassette rebuild, or whenever axial play appears in the roll set.
What do you need to quote?
Support dimensions or a sample, bearing type and quantity per cassette.
