Quick answer: the Veybelt 900 series is a 27.2 mm small-pitch plastic modular belt platform with four surface styles: flat top (closed), flush grid (31.7% open), perforated flat top (31.7% open) and raised rib (31.7% open, accepts finger transfer plates). Molding is PP, POM or PE; belt strength is 17,500 N/m in PP and 40,300 N/m in POM. One drive system covers all four surfaces via the same 900 sprockets, so swapping to a different top later means changing the belt and nothing else.
What is the 900 series?
The 900 is our small-pitch, straight-running workhorse. At 27.2 mm pitch the chordal rise at the drive shaft is small and the nose can be tight, which is what you want for small products, packaging lines and belt-to-belt integration. Need more pull? Specify POM instead of PP and belt strength goes from 17,500 N/m to 40,300 N/m, better than double, on the same platform. Belts are bricked together from molded modules on hinge rods: width is whatever the line needs, and repairs happen module by module without pulling the belt off the frame.
| Pitch | 27.2 mm |
|---|---|
| Thickness | 9 to 13.7 mm depending on surface |
| Belt strength | 17,500 N/m (PP) / 40,300 N/m (POM) |
| Materials | PP / POM / PE |
| Standard colors | Natural, Grey, Blue, Brown |
| Drive | Positive sprocket drive, 9 / 12 / 18 / 20 teeth |
Choose your surface: the four 900 variants
| Variant | Open area | Thickness | Best for | Avoid when |
|---|---|---|---|---|
| 900 Flat Top | 0% (closed) | 10 mm | Small packaged goods and loose parts that would fall into or catch in openings; keeps spills on the belt | Anything that has to drain, dry or get washed through the belt |
| 900 Flush Grid | 31.7% | 9 mm | The most drainage and airflow in the series, at the lowest belt weight (9 mm thick): washdown, rinsing, cooling, dewatering | Product feet drop into the grid openings |
| 900 Perforated Flat Top | 31.7% | 10 mm | Product that needs full support underneath but still has to rinse or air-cool; same 31.7% open area with a smooth top | The product sits fine on a grid anyway; flush grid is thinner and lighter |
| 900 Raised Rib | 31.7% | 13.7 mm | Tight end transfers with finger transfer plates; product rides the rib crowns, so contact area is minimal, water drains under it, and pushers can sweep across the ribs | Small or soft product sags between the ribs, or you need a closed containment surface |
The decision usually comes down to the product base and the transfer points. Closed base or small footprint takes flat top. Drain-or-breathe duty takes flush grid or perforated flat top. Comb-plate transfers, pusher sweeps or minimum product contact take raised rib.
Matching sprockets
One sprocket family drives all four surfaces: the 900 series sprockets, POM (acetal), low friction, slow wearing:
- Teeth options: 9 / 12 / 18 / 20 teeth, the widest range in our small-pitch lineup. Choose by shaft height and belt speed. High counts run smoother with a larger pitch diameter; low counts keep the transfer nose compact.
- Bore types: square bore (self-centering, the usual choice), round bore, or a bushing insert when the shaft is worn or non-standard.
- How many per shaft: a sprocket every 100–150 mm across the width is the normal starting count. Only the middle sprocket gets locked to the shaft; the others float sideways to take up thermal expansion.
Accessories for a complete 900 conveyor
- Finger transfer plates: comb plates that mesh with the 900 raised rib surface, so product crosses belt ends without a gap.
- Flights: vertical cleats for incline/decline sections, available for the 900 series.
- Hinge rods: spare rods for module replacement and belt repair.
- Return wheels and pressure rollers: return-path support and hold-down on inclines.
How to spec your 900 order
To quote a complete 900 line we need five inputs. Send them over and the quote comes back as a confirmed BOM.
- Surface style (flat top / flush grid / perforated / raised rib) and material (PP, POM or PE); go POM where you need the 40,300 N/m rating
- Belt width and conveyor length (center-to-center)
- Product weight and speed, ambient/washdown temperature
- Shaft size, for matching square/round/bushing bores
- Accessories: finger transfer plates (raised rib only), flights (height and spacing), return components
