Series 7

Product catalog summary

Overview
The document is an excerpt from the Siegling Prolink Engineering Manual, focusing on Series 7 straight running modular belts with a pitch of 40 mm (1.57 in). These belts are designed for heavy-duty non-food applications and are manufactured by Forbo Siegling GmbH.

Design Characteristics

Closed-hinge design for high belt pull capacity.
Small pitch relative to belt thickness, suitable for compact, heavily loaded conveyors.
Robust design with a large surface contact area for superior wear life.
Closed solid edge with a flame retardant version available (PXX-HC) compliant with DIN EN 13501-1.

Basic Data

Pitch: 40 mm (1.57 in).
Minimum belt width: 80 mm (3.15 in), 360 mm (14.2 in) for belts with FRT-surface.
Width increments: 20 mm (0.8 in).
Hinge pins: 6 mm (0.24 in) made of plastic (PBT) or stainless steel.

Belt Types and Features

S7-0 FLT: Closed, smooth surface with flat top.
S7-0 SRS: Closed, slip-resistant surface, pleasant to walk and kneel on.
S7-6 FLT: Open (6%) smooth surface for increased drainage capacity.
S7-0 NSK: Closed surface with a non-skid pattern for safety.
S7-6 NSK: Open (6%) surface with a non-skid pattern and drainage holes.
S7-0 FRT1: Closed surface with friction top and replaceable rubber pads for increased grip.

Materials and Specifications

Available in various colors: Anthracite (AT), Black (BK), Uncolored (UC), White (WT), Yellow (YL).
Complies with DIN EN 13501-1 Cfl-s1 and DIN 4102 B1 for flame retardancy.
Temperature range: -45°C to 90°C (-49°F to 194°F) for most materials.
Nominal belt pull and weight vary by material and configuration.

Applications
These belts are suitable for applications requiring high durability and specific surface characteristics, such as slip resistance or drainage capacity, in non-food heavy-duty environments.

Temperature Influence Overview
This section of the Prolink manual discusses the impact of temperature on the performance and specifications of modular belts. It emphasizes the importance of considering temperature variations when evaluating belt dimensions and tolerances, which are standardized at 21°C (69.8°F).

Flex Radii Specifications
The document outlines various flex radii for different components: r1 for side flex, r2 for front flex on rollers, r3 for back flex on load-bearing rollers, r4 for back flex on Hold Down shoes, and r5 for back flex on rollers. These specifications are crucial for ensuring the belt's flexibility and performance under varying conditions.

Compliance and Material Options
The belts comply with DIN EN 13501-1 Cfl-s1 and DIN 4102 B1 standards, indicating their flame retardant properties. Various materials and colors are available upon request, allowing customization based on specific application needs.

Material and Performance Data
The manual provides detailed data on materials used for belts, pins, and rubber components, including their nominal belt pull, weight, width deviation, and temperature range. For example, POM AT with PBT UC and R2 BK has a nominal belt pull of 3426 N/mm and operates between -45°C to 90°C (-49°F to 194°F).

Sprocket and Wheelstopper Details
The document includes specifications for sprockets and wheelstoppers, highlighting dimensions, material, and color options. It notes that all measurements are rounded to the nearest inch and advises consulting chapter 6.3 for detailed sprocket and shaft dimensions.

Pin Retained Rollers (PRR)
This section describes the use of pin retained rollers for applications requiring low back pressure accumulation or product separation. It provides formulas for calculating allowable belt pull and emphasizes the importance of proper roller positioning.

Legend and Material Codes
The manual includes a legend explaining various codes used for series, surface patterns, types, styles, colors, and materials. This helps users understand the specifications and select appropriate components for their needs.
