ARC-Power Self-Tracking Timing Belts
ARC-Power Self-Tracking Timing Belts
ARC-Power self-tracking belts are heavy-duty polyurethane timing belts that combine high power transmission capacity with integrated belt tracking for demanding conveying and transport applications. Unlike standard self-tracking belts (TK/ATK series) which are primarily designed for general drive applications, ARC-Power belts are specifically engineered for heavy-load conveying where both high torque capacity and reliable flangeless tracking are required.
Texas Belting stocks ARC-Power belts in four series: BAT (arc-tooth), BATK (arc-tooth with K-guide), SFAT (side-flange tracking), and HK13 (heavy-duty K13 guide). Each series uses a different approach to self-tracking, allowing the best match to specific conveying requirements. All ARC-Power belts support backing materials on the conveying surface for product handling applications.
- Series: BAT, BATK, SFAT, HK13
- Pitches: 10mm, 15mm, 20mm (varies by series)
- Arc-tooth profile for heavy-duty power capacity
- Self-tracking without flanged pulleys
- Designed for heavy conveying and transport
- Configurations: open-ended, welded, truly endless
- Backing options for product handling
- FDA food-grade materials available
BAT-Series (Arc-Tooth)
BAT belts feature an arc-shaped tooth profile optimized for high power capacity with integrated self-tracking guidance on the back of the belt. The arc-tooth design provides smoother engagement and higher load capacity than standard trapezoidal profiles.
| Model | Pitch | Available Configurations | Min. Pulley Teeth |
|---|---|---|---|
| BAT10 | 10mm | Open-Ended, Welded, Truly Endless | 20 |
| BAT15 | 15mm | Open-Ended, Welded, Truly Endless | 20 |
BATK-Series (Arc-Tooth with K-Guide)
BATK belts add the K-profile V-guide to the arc-tooth design for enhanced tracking stability. The K-guide provides stronger lateral centering force than the standard BAT tracking profile, making BATK the right choice for applications with higher lateral loads or steeper inclines.
| Model | Pitch | Available Configurations | Min. Pulley Teeth |
|---|---|---|---|
| BATK10 | 10mm | Open-Ended, Welded, Truly Endless | 20 |
| BATK15 | 15mm | Open-Ended, Welded, Truly Endless | 20 |
SFAT-Series (Side-Flange Self-Tracking)
SFAT belts use a side-flange tracking system instead of a back-side V-guide. The side flanges ride against the pulley edges, providing self-tracking without reducing the tooth engagement area. This gives SFAT belts the highest power capacity of any self-tracking belt because the full tooth surface remains engaged with the pulley.
| Model | Pitch | Available Configurations | Min. Pulley Teeth |
|---|---|---|---|
| SFAT10 | 10mm | Open-Ended, Welded, Truly Endless | 15 |
| SFAT15 | 15mm | Contact us for details | 20 |
| SFAT20 | 20mm | Open-Ended, Welded, Truly Endless | 18 |
HK13 Self-Tracking
The HK13 is a heavy-duty self-tracking belt with an integrated K13 (13mm) V-guide designed for the highest tracking forces in large conveyor systems and material handling equipment.
| Model | Guide | Min. Pulley Teeth |
|---|---|---|
| HK13 | K13 (13mm wide) | 18 |
ARC-Power Series Comparison
The table below summarizes the four ARC-Power series to help you select the right belt for your conveying application.
| Series | Tracking Method | Power Capacity | Best For |
|---|---|---|---|
| BAT | Integrated back guide | High | Heavy conveying with standard tracking needs |
| BATK | K-profile V-guide on back | High | Heavy conveying with stronger tracking force needed |
| SFAT | Side flanges against pulley edges | Highest (full tooth engagement) | Maximum power with self-tracking, no tooth area loss |
| HK13 | K13 V-guide (13mm) | High | Large conveyors requiring maximum lateral tracking force |
Common Applications
ARC-Power belts are specified for heavy-duty conveying applications where reliable belt tracking is critical and flanged pulleys are impractical or undesirable. Typical applications include vertical and inclined conveyor systems, heavy product transport in packaging lines, food processing conveyors requiring washdown-compatible flangeless designs, material handling and sortation equipment, and any conveyor drive where the combination of heavy loads, vertical orientation, or lateral belt forces makes flanged pulleys inadequate or impractical.
ARC-Power belts can be fitted with backing materials (rubber Supergrip, polyamide, felt, food-grade surfaces) on the conveying side, and with welded profiles for product pushing and indexing tasks.
Frequently Asked Questions
ARC-Power belts are heavy-duty polyurethane timing belts that combine high power transmission capacity with integrated self-tracking. They are designed specifically for demanding conveying and transport applications where both heavy loads and reliable flangeless belt tracking are required. They are available in four series (BAT, BATK, SFAT, HK13), each using a different approach to tracking.
BAT belts use an integrated back guide for basic self-tracking. BATK belts add a K-profile V-guide for stronger tracking force. SFAT belts use side flanges that ride against pulley edges, maintaining full tooth engagement for the highest power capacity of any self-tracking belt. HK13 belts use a 13mm K-guide for maximum lateral tracking force in large conveyor systems. The choice depends on the balance of power capacity, tracking force, and conveying requirements in your application.
Yes. Each ARC-Power series requires matching pulleys: BAT and BATK need pulleys with the correct groove profile, SFAT needs pulleys with matching edge geometry, and HK13 needs K13-grooved pulleys. Standard flat-face or AT-profile pulleys cannot be used. Texas Belting can supply matched pulley sets for any ARC-Power configuration. Call 888-203-2358 for availability.
Choose ARC-Power when the application involves heavy-duty conveying with high load requirements and self-tracking is needed. Standard TK and ATK self-tracking belts are suitable for general drive applications at moderate loads. ARC-Power belts are specifically engineered for the combination of heavy torque transmission and flangeless conveying that standard self-tracking belts cannot handle.
SFAT belts have the highest power capacity because the side-flange tracking system does not reduce the tooth engagement area. In BAT, BATK, and HK13 belts, the back-side V-guide slightly reduces the effective tooth contact, resulting in approximately 10% to 15% lower capacity compared to an equivalent non-tracking belt. SFAT avoids this trade-off entirely.
Yes. ARC-Power belts support backing materials on the conveying (non-tooth) surface. Common options include rubber Supergrip for high friction, polyamide fabric (PAZ) for low friction, felt for delicate products, and FDA-compliant materials for food processing applications. Tooth-side backings are not used as they would interfere with the tracking profile.
Yes. ARC-Power belts are available in FDA 21 CFR 177.2600 compliant polyurethane with stainless steel tension members. The self-tracking feature is particularly valuable in food conveyors where flanged pulleys create cleaning difficulties. See the food-grade timing belts page for details.
Yes. Vertical and inclined installations are a primary use case for ARC-Power belts. The integrated tracking keeps the belt centered under all operating conditions without flanges. For steep inclines, a Supergrip rubber backing can be added to the conveying surface to prevent product slippage. For vertical product transport, welded profiles (flights, cleats) can be added to carry products upward.
