Quick answer: the Veybelt 1100 series is a 15.24 mm (0.6 in) micro-pitch plastic modular belt, the smallest pitch we make in a straight-running belt. Two surfaces: flat top (fully closed, 9 mm thick) and flush grid (7.7% open). Materials are POM or PP, rated 12,300 N/m in PP and 31,100 N/m in POM. Both surfaces share the same 1100 sprockets, so a later surface change does not touch the drive.
What is the 1100 series?
The 1100 exists for transfers. At 15.24 mm the pitch is 40% finer than a 1 in platform like the 1000, so the belt articulates around very small sprocket and nosebar radii. Confectionery, baked goods, pouches, vials, electronic components: product this small passes belt-to-belt without tipping or wedging in the gap. The fine pitch also flattens chordal action, so items ride quietly through infeed and discharge instead of bouncing. If the run is long or the load adds up, order POM; at 31,100 N/m it carries more than 2.5 times what PP does. Modules are injection molded and brick-layed on hinge rods, so any width builds up and any module swaps out on site.
| Pitch | 15.24 mm (0.6 in) |
|---|---|
| Thickness | 9 mm (flat top) |
| Belt strength | 12,300 N/m (PP) / 31,100 N/m (POM) |
| Materials | POM / PP |
| Standard colors | Natural, Blue |
| Drive | Positive sprocket drive, 16 / 24 / 32 teeth |
Choose your surface: the two 1100 variants
| Variant | Open area | Best for | Avoid when |
|---|---|---|---|
| 1100 Flat Top | 0% (closed) | Tight transfers of small or tip-prone product: confectionery, biscuits, pouches, caps and closures, pharma and electronic components on a smooth closed deck | The process needs drainage, airflow or wash-through |
| 1100 Flush Grid | 7.7% | Micro-pitch lines that also have to drain or breathe: rinse and air-cool sections where 7.7% of opening sheds liquid without giving up the tight transfer | Product feet fit into the 7.7% openings, or you actually need serious open area; a larger-pitch flush grid drains far better |
Deciding is quick here. Small closed base: flat top. Has to drain and the footprint clears the openings: flush grid. One pitch, one material list, one sprocket set either way.
Matching sprockets
Both surfaces are driven by 1100 series sprockets, molded POM (acetal) running quietly against the belt hinge with little wear:
- Teeth options: 16 / 24 / 32 teeth. At 15.24 mm pitch the 16-tooth gives a very small pitch diameter, which is exactly what a tight-transfer end wants; 24 and 32 teeth fit larger shafts and faster lines.
- Bore types: most orders are square bore, which self-centers. Round bore and bushing inserts exist for worn or non-standard shafts.
- How many per shaft: figure one sprocket for every 100–150 mm of belt width. Retain the center sprocket only; leave the rest loose so the belt can move across the shaft as temperature changes.
Accessories for a complete 1100 conveyor
- Hinge rods: spare Nylon/PP rods for module replacement and belt repair.
- Return wheels and pressure rollers: keep the return strand supported and the belt held down on slopes.
- Bearing bushings and bushing inserts: axial positioning of sprockets and bore adaptation to your shaft diameter.
