Application and Use
Cutlass bearings are critical components for supporting and aligning marine propeller shafts. Their water-lubricated rubber lining minimizes friction, absorbs vibration, and ensures reliable operation under continuous marine load and exposure.
Brass vs. Phenolic Bearings
- Brass bearings: Suitable for standard marine applications, providing durability, corrosion resistance, and excellent performance under dynamic loads.
- Phenolic bearings: Used in aluminum stern tubes or where galvanic corrosion needs to be prevented.
