Rubber Coated AT Timing Belts
Reinforced Trapezoidal Synchronous Belt with Functional Rubber Surface for Precision Conveying
Product Overview
Rubber Coated AT Timing Belts are synchronous transmission belts based on the reinforced trapezoidal AT tooth profile and integrated with a bonded rubber coating layer on the belt back. This structural combination allows the belt to deliver accurate positive-drive transmission while providing enhanced surface friction, cushioning, and controlled conveying performance.
The AT tooth profile is an upgraded trapezoidal geometry featuring increased tooth height and improved rigidity compared to the standard T series. This design enhances load capacity and reduces tooth deformation under operating stress. When combined with a functional rubber coating, the belt becomes suitable for synchronized conveying systems that require both mechanical transmission strength and stable surface interaction.
Rubber Coated AT Timing Belts are widely used in industrial automation, packaging machinery, and precision positioning systems where reinforced tooth strength and reliable surface grip are required in a compact transmission layout.
Belt Structure & Materials
The durability and performance of Rubber Coated AT Timing Belts depend on the integration of a reinforced synchronous base belt and a stable rubber surface layer. Conxu applies structured manufacturing control to ensure consistent bonding strength and dimensional precision.
1. Base Belt – AT Rubber Timing Belt
The core structure consists of an endless molded AT rubber timing belt featuring:
- Reinforced trapezoidal AT tooth profile
- Industrial synthetic rubber body
- Embedded high-strength tensile cords
- Precision-controlled pitch geometry
The increased tooth height of the AT profile improves torque capacity and rigidity compared to traditional trapezoidal belts.
2. Tensile Reinforcement Layer
High-strength tensile members are accurately positioned within the belt body to provide:
- Low elongation
- Stable pitch accuracy
- Improved load-bearing capacity
- Reliable synchronous transmission
This reinforcement ensures that the belt maintains precise synchronization even under dynamic load conditions.
3. Functional Rubber Coating Layer
A customized rubber coating is bonded to the back surface to enhance operational performance. Depending on application requirements, the coating may provide:
- Increased friction coefficient
- Anti-slip functionality
- Impact absorption
- Wear resistance
- Product surface protection
Coating thickness and rubber compound formulation can be adjusted to match specific mechanical and environmental requirements.
4. Controlled Bonding Process
The coating is applied using a controlled bonding process to ensure:
- Uniform thickness distribution
- Strong adhesion to the base belt
- Stability under repeated bending
- Resistance to delamination
This integrated construction allows the belt to operate reliably in synchronized conveying systems.

Tooth Profile Comparison for Coated Timing Belts
When adding surface coating to synchronous belts, selecting the correct tooth profile is essential.
| Profile | Tooth Geometry | Torque Capacity | Load Distribution | Positioning Accuracy | Backlash Level | Suitability for Coated Belts |
|---|---|---|---|---|---|---|
| HTD | Curvilinear | High | Even | Good | Low | Very Suitable |
| STD | Optimized curvilinear | High | Optimized | Very Good | Low | Very Suitable |
| RPP | Reinforced parabolic | High | Improved contact | Very Good | Low | Very Suitable |
| RHP | Reinforced curvilinear | Very High | Enhanced load sharing | Good | Low | Suitable |
| Trapezoidal (T) | Trapezoidal | Moderate | Edge stress concentration | Moderate | Moderate | Suitable (Light-Medium Load) |
| AT | Reinforced trapezoidal | High | Improved vs T | Good | Moderate | Suitable (Medium Load) |
| GT | Optimized curvilinear | High | Smooth engagement | Very High | Very Low | Very Suitable |
AT profile provides improved mechanical strength compared to standard trapezoidal belts, making it appropriate for coated applications requiring reinforced tooth structure without switching to curvilinear systems.
