The YNT55A is a high-precision, single-stage oil-lubricated rotary screw air end engineered for the most demanding industrial applications. As the flagship compression core of the Bebaios series, the YNT55A is designed to deliver a steady, efficient air supply while maintaining an exceptionally long service life.
What sets the YNT55A apart is its Global Compatibility. Built on a standardized technical platform, its internal components—including bearings and seals—are universal specifications. This means that no matter where your equipment is installed, genuine maintenance parts are easily accessible locally, ensuring zero-risk operation and minimal downtime for global industrial users.
Designed for the international market, all high-wear parts (SKF/FAG bearings and seals) are standard industrial sizes, making maintenance easy and affordable worldwide.
Featuring a specialized 6-bearing arrangement, the YNT55A is built for 24/7 continuous operation with a design life exceeding 60,000 hours.
The integrated casting housing is optimized for superior heat dissipation, allowing the air end to maintain stable performance even in high-ambient temperature environments (up to 45°C-50°C).
Every unit is dynamically balanced using advanced CNC grinding technology, resulting in whisper-quiet operation and extended service intervals for the entire compressor package.
