GB Series
Graphite bearings are made from high-strength carbon graphite material, designed for rotating equipment that承受s higher radial loads. Excellent self-lubricating properties make them particularly suitable for applications where grease lubrication is impossible or maintenance is difficult. Widely used in marine stern shaft bearings, pump bearings, agitator bearings, and various industrial machinery, operating stably in water, oil, and various chemical media.

GB series graphite bearings can handle radial loads ranging from 5~20 MPa depending on the grade and impregnation process. Provide specific operating parameters for the best grade recommendation.
Yes. Graphite bearings with corrosion-resistant impregnation operate stably long-term in seawater, making them ideal for marine stern shaft and seawater pump bearings.
