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.

Installation & Maintenance Tips
- Ensure pulleys are aligned within ±0.5 mm to avoid uneven wear.
- Tension the belt to the recommended preload specified in the manufacturer documentation.
- Inspect visually every 200 operating hours for glazing, fraying, or edge damage.
- Replace if cracking or excessive wear appears to prevent slippage or drive failure.
- When replacing, release tensioner, remove worn belt, align pulleys, install new belt, and re-tension.
Benefits of Using the 125834 Belt
- Improved uptime due to reduced slippage and consistent torque transfer.
- Longer service life thanks to reinforced materials and resistance to heat and chemicals.
- Stable operation even in demanding spraying environments.
- OEM-matched component ensures reliable replacement fit and performance.
Frequently Asked Questions
The 125834 belt uses the AX48 cogged V-belt specification. Refer to the Graco parts manual for exact length and width details.
It may fit machines that require an AX48 belt, but correct pulley dimensions and tension requirements must match. Compatibility should always be confirmed before installation.
Inspect the belt every 200 hours of operation. Replace as soon as any glazing, cracking, or slipping is detected.
No lubrication is required. The belt is designed to operate dry, and lubricants may reduce friction or damage the material.
