Series 5

Product catalog summary

Overview: This document is a technical manual for Siegling Prolink Series 5 modular belts, focusing on side flexing and spiral belts with a pitch of 25 mm (0.98 in). It provides detailed specifications, design characteristics, material options, and compliance information for various belt types.

Design Characteristics: The belts are designed for both straight and radius conveying, featuring up to 45% open area for optimal air circulation and drainage. They include stainless steel hinge pins for high load capacity and lateral stiffness, reducing belt lifting in curves and preventing edge catch points.

Specifications: The belts have a pitch of 25 mm, with a minimum width of 100 mm and width increments of 25 mm. Hinge pins are 5 mm in diameter, made of stainless steel. Several belt types are detailed, including S5-45 GRT, S5-45 NTP, S5-39 FRT1, and S5-33 FRT2, each with specific open areas and surface designs.

Materials and Colors: Available materials include PE, PP, POM-CR, and PA, with color options such as white, dark blue, blue, beige, and black. Each material has specific temperature ranges and complies with FDA and EU regulations.

Technical Specifications: Detailed measurements and tolerances are provided for each belt type, including pitch, pin diameter, thickness, and minimum flex radii. Nominal belt pull capacities are outlined for straight and curved applications.

Compliance and Certifications: The belts comply with FDA 21 CFR, EU regulations (10/2011 and 1935/2004), and Japanese MHLW Notification 370, ensuring raw materials meet migration thresholds and safety standards.

Procedures: Installation instructions for sprocket and shaft dimensions are included, with guidance on temperature influence on belt dimensions and performance.

Recommendations: Accessories may impact minimum design radii, and specific configurations are recommended for optimal performance. For high-speed applications, ball-bearing support is advised to minimize friction.

Key Features: The belts offer excellent air circulation and drainage, integrated friction pads for increased surface friction, and reinforced side modules for enhanced belt pull capacity.

Additional Information: The document highlights restrictions on sprocket size and shaft options, advising consultation of the sprocket data sheet for compatibility. It also notes that belts made from PA material will absorb water in wet environments, affecting their nominal belt pull capacity.
