Quick answer: the Veybelt 400 series is a 50.8 mm (2 in) pitch, heavy-strength plastic modular belt platform rated at 39,200 N/m (PP). Two surfaces: flush grid (15.9 mm thick) and raised rib (21.5 mm thick), both 29.4% open, built in widths in multiples of 50.8 mm on the same 10/12/16-tooth 400 sprockets. Shared sprockets make the surface decision reversible; the frame and shafts stay put.
What is the 400 series?
The 400 is the heavy end of our straight-running range. At 39,200 N/m (PP) it carries the highest belt strength of our 50.8 mm pitch platforms, which is why it ends up on long conveyors, heavy unit loads and hard industrial service: cases, crates and totes, tire and lumber lines, pallet-adjacent transport, washdown sections that still carry real weight. Both surfaces pass water and air freely through the 29.4% open area. Modules are injection molded in PP or PE and brick-lay on hinge rods in 50.8 mm width steps; site repair means pulling a rod and dropping in fresh modules.
| Pitch | 50.8 mm (2 in) |
|---|---|
| Belt strength | 39,200 N/m (PP) |
| Thickness | 15.9 mm (flush grid) / 21.5 mm (raised rib) |
| Open area | 29.4% (both surfaces) |
| Materials | PP / PE |
| Standard colors | Grey, Natural, Brown |
| Standard width | Multiples of 50.8 mm |
| Drive | Positive sprocket drive, 10 / 12 / 16 teeth |
Choose your surface: the two 400 variants
| Variant | Open area | Best for | Avoid when |
|---|---|---|---|
| 400 Flush Grid | 29.4% | Heavy washdown and draining duty: crates, cases and totes on long or hard-pulling conveyors where the 39,200 N/m rating and wash-through cleaning both earn their keep | Small or unstable product has to cross the discharge flush; that is a raised rib and finger plate job |
| 400 Raised Rib | 29.4% | Tight product transfer. The ribs accept finger transfer plates for a near gap-free discharge, carry product on minimal contact area, and leave room between ribs for dewatering and pusher-style side transfer | Product is narrow or floppy enough to sag between the ribs, or the job wants a full flat carrying plane |
Strength and open area are identical on both, so decide by the transfer and the product base. Stable cases and totes with conventional end transfers run on flush grid. Small, unstable or end-transferred product that must cross the discharge without tipping goes on raised rib with finger transfer plates.
Matching sprockets
Both belts drive on the same POM (acetal) 400 series sprockets:
- Teeth options: 10 / 12 / 16 teeth. Drive shaft height and belt speed make the call; a higher count engages more smoothly and gives a larger pitch diameter.
- Bore types: square bore (self-centering, fitted on most builds), round bore, or a bushing insert for worn or non-standard shafts.
- How many per shaft: baseline is one sprocket per 100–150 mm of belt width. Lock the center sprocket; the outboard ones must stay free to float on the shaft or thermal expansion will bow the belt.
Accessories for a complete 400 conveyor
- Flights: vertical cleats in 50 / 102 / 150 mm heights for incline/decline sections, compatible with the 400 series.
- Finger transfer plates: comb plates that mesh with the raised rib surface for a near gap-free discharge.
- Hinge rods: spare Nylon/PP rods for module replacement and belt repair.
- Return wheels and pressure rollers: return-path support and hold-down for incline/decline sections.
- Bearing bushings and bushing inserts: sprocket axial positioning and bore adaptation to your shaft diameter.
