Graco 125834 Tri-Power AX48 Belt Details
The Graco 125834 Belt, Tri-Power AX48 is a high-performance V-belt engineered for durability, high torque, and continuous operation in industrial fluid-handling systems. Made from abrasion-resistant polyurethane reinforced with tensile fibers, it offers chemical resistance and long service life under load. The “Tri-Power” design helps minimize slippage, provide consistent tension, and enable smoother starts while maintaining drive efficiency throughout extended cycles.
Key Features
- Material: Reinforced polyurethane with high-tensile core
- Design: Cogged V profile (AX48) for secure grip
- Performance: High torque capacity, low stretch under load
- Durability: Chemical, ozone, and heat resistant outer layer
- Maintenance: Reduced wear on pulleys, longer maintenance intervals
Applications
This belt is well-suited for hydraulic-powered airless sprayers, especially in high-output contractor settings. It is optimized for systems that require reliable drive performance such as construction, industrial coating, and texture spraying.
