Sliding bearings:

1. High load - bearing capacity:  It can bear large radial and axial loads, and is suitable for heavy - load and high - impact working environments. 

2. Low friction loss : With a low friction coefficient, it can reduce energy loss and improve overall efficiency.

2. Simple structure :Simple in design, easy to install and maintain. 

High - speed deep - groove ball bearings:

1. High - speed deep - groove ball bearings : It can operate stably at high speeds, meeting the high - speed requirements of the main shaft motors of large - scale ships.

2. Load - bearing capacity : It can bear radial and axial loads simultaneously and has a compact structure.

3. Low noise and vibration : It generates less noise and vibration during operation, improving the overall stability. It can bear radial and axial loads simultaneously and has a compact structure.

Thrust bearings:

1. Thrust bearings :  Used to bear axial loads, suitable for the thrust requirements of the main shafts of large - scale ships.

2. High rigidity and stability:  With excellent rigidity and stability, it can maintain an accurate working state under high loads.

2. Load - bearing capacity : It can bear radial and axial loads simultaneously and has a compact structure.

Additional Notes:
