ATN Convertible Profile Timing Belts
ATN Convertible Profile Timing Belts
ATN Convertible belts are polyurethane timing belts with T-shaped slots molded into the back surface that accept snap-in conveying profiles. Profiles can be installed, repositioned, and removed by hand without tools, adhesive, or welding. This allows a single belt to be reconfigured in minutes when conveying requirements change, saving hours of downtime compared to traditional welded-profile conveyor belts.
Texas Belting stocks ATN belts in three pitches (ATN10, ATN12.7, and ATN20) with a wide selection of standard and custom snap-in profiles including flights, cleats, dividers, pushers, and cup holders. ATN belts use the AT-type curvilinear tooth profile for positive drive engagement, and are also available in FDA-compliant food-grade materials. For welded (permanent) profile belts, see the profile timing belts page.

ATN10: 10mm Pitch
The most compact ATN pitch for light to medium-duty conveying. ATN10 is widely used in packaging lines, small parts handling, and sorting systems where frequent profile changes are needed.
| Configuration | Available Widths (mm) | Details |
|---|---|---|
| Open-Ended | 25, 32, 50, 75, 100 | Sold per meter, cut to length |
| Truly Endless | 25, 32, 50, 75, 100 | Standard pitch lengths available |
ATN12.7: 12.7mm (1/2") Pitch
A unique pitch that bridges metric and imperial sizing for maximum design flexibility. The ATN12.7 provides higher load capacity than ATN10 while remaining compatible with 1/2" pitch imperial drive layouts.
| Configuration | Available Widths (mm) | Details |
|---|---|---|
| Open-Ended | 25, 32, 50, 75, 100 | Sold per meter, cut to length |
| Truly Endless | 25, 32, 50, 75, 100 | Standard pitch lengths available |
ATN20: 20mm Pitch
The heavy-duty ATN option for large product handling and high-load conveying. ATN20 belts accept the largest snap-in profiles and are used in heavy conveyor systems, palletizing equipment, and industrial material handling.
| Configuration | Available Widths (mm) | Details |
|---|---|---|
| Open-Ended | 32, 50, 75, 100, 150 | Sold per meter, cut to length |
| Truly Endless | 32, 50, 75, 100, 150 | Standard pitch lengths available |
ATN Pitch Comparison
The table below compares the three ATN pitches, including the T-slot width that determines which snap-in profiles each pitch accepts.
| Profile | Pitch | Belt Height | Tooth Height | Slot Width | Applications |
|---|---|---|---|---|---|
| ATN10 | 10mm | 7.5mm | 3.5mm | 5.0mm | Light to medium conveying, packaging |
| ATN12.7 | 12.7mm (1/2") | 9.0mm | 4.5mm | 6.0mm | Versatile, bridges metric and imperial |
| ATN20 | 20mm | 14.0mm | 7.0mm | 8.0mm | Heavy-duty conveying, large product handling |
ATN Connecting Kits
ATN belts can be joined in the field using connecting kits, eliminating the need for factory splicing. This allows on-site belt installation and length adjustments without removing the conveyor from service. For additional field joining methods, see the connecting and joining belts page.
| Version | Type | Application |
|---|---|---|
| Version C | Single-sided connection | Standard applications, moderate loads |
| Version DC | Double-sided connection | Higher load capacity, improved joint strength |
| Version DC-PRO | Professional double-sided | Maximum strength and reliability for demanding applications |
Available Snap-In Profile Types
ATN snap-in profiles are available in a wide range of shapes and materials to match specific product handling requirements. Profiles are manufactured in polyurethane, rubber, silicone, and FDA-compliant food-grade materials.
| Profile Type | Function | Common Applications |
|---|---|---|
| Straight flights | Product pushing and separation | Incline conveyors, spacing, indexing |
| Angled flights | Directional product diverting | Sorting lines, merge/divert stations |
| T-cleats and L-cleats | Product retention and backstops | Incline and decline conveyors |
| Finger separators | Individual product isolation | Bottling, pharmaceutical packaging |
| Cup holders | Round product nesting | Bottle and can handling |
| Custom-molded shapes | Application-specific geometry | Any specialized product shape |
Common Applications
ATN Convertible belts are specified wherever conveyor flexibility is a priority. Typical applications include packaging lines with frequent product changeovers, food and beverage bottling and filling systems, pharmaceutical blister pack and cartoning equipment, contract packaging operations that handle multiple product formats, e-commerce fulfillment sorting systems, and any conveyor application where downtime for profile changes must be minimized.
Frequently Asked Questions
ATN belts have T-shaped slots molded into the back (non-tooth) surface. Conveying profiles have a matching T-shaped base that snaps into these slots by hand. No adhesive, welding, or special tools are required. Profiles can be repositioned, replaced, or reconfigured in the field in minutes, allowing the same belt to be adapted for different products or line configurations.
ATN profiles snap in and out of the belt by hand. A typical profile changeover on a conveyor line can be completed in minutes rather than the hours required for welded profile belts. This makes ATN belts ideal for contract packaging operations and lines that handle multiple product formats.
ATN belts are available in ATN10 (10mm pitch), ATN12.7 (12.7mm / 1/2 inch pitch), and ATN20 (20mm pitch). The 12.7mm pitch is unique to the ATN series and bridges metric and imperial sizing. Choose ATN10 for light-duty conveying, ATN12.7 for medium loads with imperial compatibility, and ATN20 for heavy-duty product handling.
Yes. In addition to hundreds of standard profile shapes (flights, cleats, dividers, pushers, cup holders), custom profiles can be manufactured to match specific product geometries and conveying requirements. Contact Texas Belting at 888-203-2358 with your application details for custom profile options.
Yes. ATN belts function as standard power transmission timing belts without any profiles installed. The T-slots on the back surface do not interfere with pulley engagement on the tooth side. This allows the same belt to serve as both a power transmission belt and a configurable conveyor belt.
Yes. ATN belts are available in FDA 21 CFR 177.2600 compliant polyurethane with stainless steel tension members. Food-grade snap-in profiles are also available, creating a fully hygienic convertible conveying system suitable for food processing and pharmaceutical applications. See the food-grade timing belts page for details.
Yes. ATN connecting kits (available in Version C, DC, and DC-PRO) allow belts to be joined on-site without welding equipment. This enables field installation and length adjustments without removing the conveyor from service. For more on field joining methods, see the connecting and joining belts page.
ATN snap-in profiles offer maximum flexibility: profiles can be changed, repositioned, or removed in minutes without tools. Welded profiles offer higher attachment strength and are better for permanent installations where the profile configuration never changes. ATN is the better choice for lines with frequent product changeovers, contract packaging, and applications where conveyor flexibility reduces downtime. Many facilities use both systems across different lines.
