Features:
1. The unit adopts the big bearing to support the structure of the barrel rotated by the main engine, which can improve the rotating speed, accuracy, stability and extend the service life of the bearings.

2. Big bearing lubricated by the specialized hydraulic lubrication station with high performance, it also used labyrinthic seal ring, which is reliable ,no leakage and high production efficiency.

3. The barrel adopts three windows structure, entirely weld and distressing technology, good rigidity, high axiality, good stability.

4. The unit foundation is made of joint steel welded entirely, the up and down surfaces are  processed by the large-scale miller to improve the installation accuracy .

5. The both ends of barrel are assisted by the bearing, with high installation accuracy, stable operation, low noise, high speed rotation.
