Uncover the Power of Cutlass Bearings: Enhance Vessel Performance and Efficiency

Cutlass bearings are the unsung heroes of the marine industry, silently ensuring smooth operation and extended longevity of propeller shafts. These precision-engineered components play a critical role in safeguarding vessels from costly repairs and downtime.

Cutlass Bearings: The Essential Components for Marine Propulsion

Cutlass bearings are cylindrical, rubber-lined bearings that provide support and reduce friction between the propeller shaft and the stern tube. Their unique design allows for slight misalignment, compensating for hull movement and vibrations.

Bearing Type	Material	Applications
Rubber	Nitrile, EPDM	General marine vessels
Bronze	Manganese bronze	Heavy-duty commercial vessels
Composite	Fiberglass, carbon fiber	High-performance racing boats

Parameter	Value
Bearing Diameter	20-150 mm
Bearing Length	10-500 mm
Maximum Shaft Speed	2,500-5,000 RPM

Proven Benefits of Cutlass Bearings

Cutlass bearings offer numerous advantages that enhance vessel performance and efficiency:

Reduced Friction: The smooth rubber lining minimizes friction, reducing energy loss and improving propulsion efficiency.

Prevents Wear: The robust construction of cutlass bearings prevents premature wear of the propeller shaft, extending its lifespan.

Quieter Operation: Cutlass bearings effectively absorb vibrations and noise, creating a more comfortable working environment for crew and passengers.

Extended Maintenance Intervals: Properly installed and maintained cutlass bearings can significantly extend maintenance intervals, reducing downtime and operational costs.

Success Stories
