Roll End Sleeves for Tension Leveller Cassettes
The roll end sleeve sits at both sides of the work rolls in a tension leveller cassette and restricts the axial movement of the work roll and intermediate roll. It is assembled with bearings, so dimensional precision decides how well the roll set stays located.
- Size 38 by 100 mm
- Black coated surface
- Assembled with bearings
- Restricts axial movement of work and intermediate rolls
Key Benefits
Small part, specific job.
Axial Location Maintained
By restricting axial movement of the intermediate and work rolls, the sleeve keeps the roll set where the cassette design intends.
Precise Fit With Bearings
The sleeve is assembled with bearings, and precise sizing is what makes that assembly reliable.
Durable Structure
The structure is reliable and durable in continuous cassette service, with a coated surface for protection.
Where It Is Used

How It Compares
Sleeve options.
| Ceramic bead roll end supports | The plain sleeve suits positions where the ceramic bead head is not required. |
|---|---|
| Re using worn sleeves | A worn sleeve lets the roll drift axially, which changes the roll set geometry. |
| Non standard replacements | Precise sizing to the original drawing keeps the bearing assembly correct. |
