modular belts

Straight running belts | Pitch 8 mm (0.31 in)
Belts for light-duty food and non-food nose bar applications

Side view scale 1:1

Available surface pattern and opening area

S13-0 FLT
Closed, smooth surface

8 (0.31)

Design characteristics
S13-0 NPY
Closed surface
with negative pyramid pattern– Micro pitch belt with small transfer gaps
– Designed to run over nosebars/knife edges or rollers witha radius down to 3 mm (0.12 in) allowing, precise transferof even the smallest products– Versatile for conveying, drying and cooling applications

S13-0 CTP
Closed surface and pointed studs– Optimal design of sprocket teeth, and belt underside provides superior sprocket engagement, safe belt tracking
and favorable cleanability– Belt and sprocket design ensures superior load transmission and belt pull capacity

S13-34 FLTOpen (34 %), smooth surface– Headless pin making it very easy to install and remove thebelt for maintenance
