Proven Performance & Long Lifespan – From Drydock to Drydock
The World’s Most Reliable Water-Lubricated Bearings for Marine Vessels, Trusted Since 1862.
The Challenge
Maintaining Peak Performance to your next drydock – and beyond
Marine vessels operate in some of the harshest environments on earth. Stern tube and propeller shaft bearings face constant stress, vibration, and exposure to saltwater and potential abrasives. Traditional bearing solutions often fall short, leading to:
- Costly Downtime: Unscheduled dry-docking and repairs due to bearing failures.
- Shaft Damage: Scoring and wear caused by inferior bearing materials.
- Oil Leakage: Environmental damage, regulatory penalties, and reputational harm.
- Frequent Replacements: Short lifespans of composite and plastic bearings.
- High maintenance costs: Forced lubrication systems add complexity.
Lignum Vitae water-lubricated bearings offer a proven, sustainable, and superior alternative, ensuring reliable performance and protecting our oceans.
The Lignum Vitae Advantage
Unmatched Reliability for Marine Vessels
A Century of Service
From the earliest sailing vessels to modern day aircraft carriers, Lignum Vitae bearings have a proven track record in demanding marine applications. They outlast complex composite bearing systems by 4X, minimizing maintenance and maximizing on-charter time.
100% Oil-Free, Zero Pollution
Eliminate additional complex lubrication systems and the risk of accidental discharge. Lignum Vitae is naturally self-lubricating and completely biodegradable. PFAS Free.
Built to Withstand the Toughest Conditions
From the abrasive waters of the Amazon to the harsh conditions of the open ocean, Lignum Vitae evolved to handle it all. As the hardest of ironwoods it is dense, durable, and resistant to rot, water, and insects.
Shaft-Friendly Material
The hardest of the ironwood species, Lignum Vitae is still softer than steel, and its self-lubricating properties help flush away sand and silt. This means no scoring or damage and no need for expensive returning of the shaft.
Naturally Self-Lubricating
Lignum Vitae is saturated with resin that lubricates as it heats. This allows it to lubricate in two modes – direct AND hydrodynamic – in comparison with composite bearings single direct mode.
The Tightest Tolerances
Lignum Vitae’s unique cellular structure helps it mold to imperfect shaft surfaces.
