Xiamen King Long Touring Car Bus Air Conditioner Double-groove
Idler Pulley
A comfortable cabin climate is essential for passenger
satisfaction, and the heart of this comfort is a flawlessly
operating air conditioning system. A worn or seized idler pulley
can disrupt the entire system, causing loud belt noise, premature
belt wear, and a complete loss of air conditioning. Nanjing
Dingguan Auto Parts Co., Ltd. proudly manufactures this Dual-Groove Air Conditioning Idler Pulley, the definitive replacement part for Xiamen King Long coaches and buses.
This is not just a pulley; it is a precision-engineered component
designed to maintain the integrity and efficiency of your vehicle's
A/C belt drive system.
Key Features & Benefits:
- Precision-Engineered Dual-Groove Design: Perfectly matches the dual-groove A/C belt used in King Long
buses, ensuring perfect belt alignment and stable power
transmission to the A/C compressor, preventing belt slippage and
ensuring optimal performance.
- High-Quality Internal Bearing: At its core is a durable, high-speed bearing designed for
continuous use. It provides smooth, quiet rotation and exceptional
longevity, minimizing friction and wear.
- Robust Construction: Manufactured from high-strength materials to withstand the
constant tension and high temperatures of the engine bay, this
pulley is built for long-term durability and resistance to wear and
tear.
- Guaranteed Direct-Fit Replacement: Engineered to OEM specifications for a seamless, bolt-on
installation. No modifications are required, saving mechanics
valuable time and labor costs.
- Restores System Integrity: Replacing a worn pulley is critical for maintaining correct belt
tension. This ensures the A/C compressor operates at peak
efficiency, delivering consistent, powerful cooling to the cabin.
As a specialized manufacturer, Nanjing Dingguan is your trusted
partner for reliable, high-performance aftermarket components that
keep your fleet running smoothly.
