25.4 mm (1.0 in)

Product catalog summary

Overview

This document compiles comprehensive technical specifications, material options, mechanical properties, accessory details, and installation guidelines for Ammeraal Beltech's uni series plastic modular conveyor belts and sprockets. It covers multiple belt series including uni S-MPB, uni SNB M2, uni JCB Y, uni QNB, and uni CNB, designed primarily for straight running conveyor applications with a nominal pitch of 25.4 mm (1.00 in).

1. Belt Specifications

Nominal Pitch: Consistently 25.4 mm (1.00 in) across all series.
Surface Types and Openings: Variants include flat, ribbed, rough top, and Y pattern surfaces with surface openings ranging from 0% (closed) to 34% depending on belt type.
Backflex Radius: Ranges from 23.0 mm (0.91 in) to 40.0 mm (1.60 in) depending on belt series.
Pin Diameter: Typically 4.0 mm to 8.0 mm depending on belt type.
Materials: Belt materials include POM-D, POM-SLF, PP, PE, and variants with multiple color options; pin and lockpin materials include PP, PE, PA6.6, PBT, and stainless steel (SS304).
Tolerances: General belt width tolerance is +0/-0.4% at 23°C (73°F) and 50% relative humidity; non-standard widths available on request in increments of 12.7 mm (0.50 in) or 76.0 mm (3.00 in).
Belt Widths: Standard widths range from approximately 39 mm (1.5 in) up to nearly 3,000 mm (117 in), with customization options.

2. Mechanical Properties and Load Capacities

Permissible Tensile Forces: Vary by belt width and material combination, e.g., from around 500 N for narrow PP belts up to over 104,000 N for wide POM-based belts.
Maximum Load per Drive Sprocket: Typically ranges from 500 N to 2,300 N depending on belt and pin materials.
Belt Weight: Varies with width and material, from approximately 0.3 kg/m to over 24 kg/m.
Minimum Number of Drive Sprockets per Shaft: Specified per belt width to ensure proper load distribution and durability.
Wear Strip Recommendations: Maximum spacing of 152 mm (6 in) on the carry side and 304 mm (12 in) on the return side to prevent premature belt wear.

3. Sprocket Specifications

Types: Molded, machined, and two-part sprockets available.
Pitch and Tooth Width: Standard pitch 25.4 mm (1.00 in); tooth widths vary by belt series (6.0 mm to 12.7 mm).
Sprocket Width: Typically 25.0 mm (0.98 in).
Bore Sizes: Range from approximately 19.1 mm to 90.0 mm with keyways; custom bore sizes available on request.
Load Considerations: Maximum load per sprocket specified but does not account for bore size; shaft sizing must be adequate for applied loads.
Accessories: Retainer rings available (refer to separate datasheet).

4. Accessories and Additional Components

Side Guides: Made from closed PP-I material with minimum indent dimensions and backflex radius of 75.0 mm (2.95 in).
Flights and Pushers: Flat and ribbed types with specified link sizes and widths; materials and colors vary by application.
Rubber Tops: Available in flat and tab types with defined dimensions and materials.
Finger Plates and Sliders: Designed for specific belt series to accommodate width variations and surface profiles.
Bottom Guides and Tabs: Provided with dimensional and material specifications for proper belt guidance.

5. Installation and Handling Guidelines

Follow uni Assembly Instructions specific to each belt series for correct sprocket positioning and belt installation.
Ensure shaft diameter and keyway sizing are adequate to handle maximum sprocket loads.
Maintain recommended wear strip spacing to extend belt life.
Consider environmental conditions (temperature, humidity) as they affect belt tolerances and performance.
