Product catalog summary

Overview

The uni ACB Closed is a plastic modular belt designed for straight running conveyor applications. It features a nominal pitch of 40.0 mm (1.57 in) and a closed flat surface type, providing a smooth conveying surface with no openings. The belt is constructed primarily from POM-NL material with pin and lock components made from PA6.6 or PP, with options for stainless steel pins.

Specifications

Belt Tolerance: +0/-0.4% at 23°C/73°F and 50% relative humidity.
Nominal Pitch: 40.0 mm (1.57 in).
Backflex Radius: 60.0 mm (2.36 in).
Pin Diameter: 6.0 mm (0.24 in).
Surface: Closed flat surface.
Material Options: POM-NL for belt, PA6.6 or PP for pins and locks; stainless steel pins available.
Safety Edges: Optional orange or yellow edge links mounted alternately along belt edges.

Mechanical Properties and Dimensions

The datasheet provides detailed permissible tensile forces, belt weights, and minimum number of drive sprockets for various belt widths ranging from 203 mm (8.0 in) up to 4005 mm (157.7 in). Key data points include:

Belt Width (mm/in)	Permissible Tensile Force (N/lbf) POM-NL/PA6.6	Permissible Tensile Force (N/lbf) POM-NL/SS	Belt Weight (Kg/m / Ib/ft) POM-NL/PA6.6	Belt Weight (Kg/m / Ib/ft) POM-NL/SS	Min. Drive Sprockets per Shaft	Min. Wear Strips

Additional standard belt widths are available in increments of 50.7 mm (2.00 in), with non-standard widths available in 16.9 mm (0.67 in) steps.

Accessories and Inserts

The belt can be equipped with various inserts to increase contact area and wear surface:

EC Grip Surface: Electrical conductive insert made from POM-EC K material, increasing contact area from 25% to 49%, with surface resistivity of 1x10⁶ Ohm per IEC 60093/ASTM D257.
Wheel Plate Insert: Made from POM DK O, increasing contact area from 25% to 38%.
Flights and Pushers: Available in POM-NL material with specified dimensions; backflex radius increases to 120 mm (4.72 in) when flights are used.

Sprockets

Sprockets are designed to match the belt specifications with the following key features:

Standard sprocket tooth width: 6.5 mm (0.25 in).
Sprocket width: 33.2 mm (1.31 in).
Available in various sizes with bore diameters of 60, 90, and 120 mm.
Two-part and machined sprockets available upon request.
Max load per sprocket is specified but does not account for bore size; shaft sizing must be adequate for load.
