Application and Use
Cutlass bearings are vital components for supporting and aligning marine propeller shafts. Their water-lubricated rubber linings minimize friction, absorb vibration and ensure dependable long-term performance in harsh marine environments.
Brass vs. Phenolic Bearings
- Brass bearings: The preferred choice for standard marine applications thanks to strength, corrosion resistance and excellent load-handling capability.
- Phenolic bearings: Recommended for aluminum stern tubes or environments where galvanic corrosion must be avoided.
