Series 11

Product catalog summary

Overview: This document is an excerpt from the Siegling Prolink Engineering Manual, detailing Series 11 side flexing belts with a 25 mm pitch. These modular belts are intended for light-duty applications in both food and non-food sectors, offering various surface patterns and materials.

Specifications:

Pitch: 25 mm (0.98 in)
Belt Width: Ranges from 175 mm (6.9 in) to 1000 mm (39.37 in), in 25 mm increments
Materials: Plastic (PBT) and stainless steel pins
Temperature Range: Varies by material, e.g., POM-CR from -45°C to 90°C (-49°F to 194°F)

Belt Types:

S11-45 GRT: Features a 45% open area with a lattice-shaped surface and replaceable caps, ideal for air circulation and drainage.
S11-45 GRT HD: Similar to GRT but includes Hold Down caps for added stability.
S11-33 FRT2: Has a 33% open area with a friction top for enhanced grip, featuring integrated friction pads.

Design Characteristics:

Lightweight all-plastic construction with tight radius capabilities.
Fixed outermost hinge to prevent deflection and edge catch points.
Suitable for both straight and radius conveying.
Optimized force transmission through inward offset sprockets and external idler support.

Sprockets and Idlers:

Available in various sizes with round or square bores.
Material: PA, Color: Light Gray.
Designed for side support and return roller without tooth engagement.

Compliance and Certifications:

Complies with FDA 21 CFR, EU regulations (10/2011 and 1935/2004), and Japanese MHLW Notification 370.

Additional Notes: Detailed measurements and tolerances are applicable at 21°C, with considerations for temperature deviations. More materials and colors are available upon request.

Idler Installation and Specifications: Refer to Chapter 5.2 for detailed sprocket installation instructions. Idler specifications include sprocket sizes with varying numbers of teeth (Z6 to Z20) and dimensions in millimeters and inches. Shaft bores are available in round and square shapes, ranging from 25 mm to 1.5 inches. The material used is Polyamide (PA) in light gray.

Modular Belts Series 11: This section covers the side flexing belt with a 25 mm pitch. Basic data includes color options such as Blue, Dark Blue, Uncolored, and White. Measurements are standardized at 21°C, with temperature deviation considerations outlined in Chapter 4.4. The open version base module for drainage is specified with a molded width of 100 mm (3.9 in).

Legend and Material Specifications: The legend provides a guide to series, open area, surface patterns, types, styles, colors, and material specifications. Key materials include Polyamide, Polyethylene, Polyoxymethylene, and Polypropylene, each with specific properties like high temperature resistance, impact resistance, and metal detectability. Note that colors may vary due to production processes.
