Flexible conveyor belt 9.1

spiralperforatedcurved

Product overview
Spiral and side-flexing conveyor belt with 50 mm pitch, designed for medium to heavy‑duty food and non‑food conveying. Suitable for spiral towers with cage drives as well as straight and curved conveying systems.

Design characteristics

• Side‑flexing modules in a brick pattern for high tensile loads
• Clip‑free hinge pin attachment for reliable jointing
• Stainless steel hinge pins (6 mm) for high load capacity and excellent lateral stiffness
• Reduced belt support and stable belt position in curves
• Adjustable collapse factor (Cc) from 1.3 to 2.9 to adapt to spiral geometry

Basic data
Pitch: 50 mm (1.97 in)
Belt width min.: 100 mm (3.9 in)
Width increments: 50 mm (1.97 in)
Hinge pins: 6 mm (0.24 in), stainless steel

S9.1-57 GRT (CW/CCW) | 57% Opening | Grid top
Spiral belt variant with 57% open area for excellent air circulation and drainage. Contact area 31%; largest opening Ø = 24 mm (0.94 in). Lattice‑shaped surface with clip‑free hinge pin fitting. Special inner‑radius edge modules (SMT) allow the collapse factor to be adjusted (Cc = 1.3–2.9) and ensure smooth conveying.

Sprockets
Available in various sizes with round or square sprocket bore to suit different drives and shaft types.

Media
2D and 3D CAD data available. Assembly and installation video available.
