Fixed sections
Sections clamped on a shaped shaft or by through bolts; replacement requires partial disassembly.
Sectional brushes
A sectional brush is a set of identical sections mounted on a common shaft. Sections tile the working length; a worn section can be replaced without touching the rest, at the cost of joints between sections.
Variants
Split sections
Two-part sections mounted without removing the shaft; the joint line must match the load.
Mixed layouts
Full sections with spacer rings or end elements; the layout is recorded in the request.
Dimensions to check
Parameters for a sectional brush request
| Parameter | What to state |
|---|---|
| Section width | Axial width of one section and the tolerance between sections. |
| Working length | Total covered length and how joints are distributed along it. |
| Section diameter | Outside diameter over filament and bore or seating on the shaft. |
| Shaft | Diameter and profile, section fixing method. |

Limits and caveats
- Joints between sections leave narrow gaps; the practical effect depends on the material and the belt.
- Section layout is integer geometry — see the section layout tool, not an installation instruction.
- Mixing sections from different manufacturers is not assumed compatible.
Versus a roller brush: A roller brush is one continuous working surface; a sectional brush trades continuity for replaceability. The comparison is editorial: the choice belongs to the engineer and the manufacturer.
