What Is a Water Lubricated Bearing?
A water lubricated bearing is a type of sliding bearing that uses water—fresh or seawater—as its primary lubricant. Unlike oil-lubricated systems, it does not require external lubricants, reducing pollution, maintenance needs, and operational costs.
They are particularly suitable for applications like:
- Marine stern tube and rudder bearings
- Vertical and horizontal water pumps
- Water turbines and hydro guide bearings
- Ship propulsion shafts and dredging equipment
By eliminating oil circulation systems, water lubricated bearings deliver cleaner, simpler, and safer solutions for critical rotating machinery.
Techemer Material Advantages
All of our water lubricated bearings are made with proprietary Techemer elastomeric polymer alloy, developed in-house by Techemer's R&D team. These materials feature high-performance self-lubricating microcrystals and extreme pressure particles that ensure long service life, even in severe conditions like dry starts, abrasive environments, and high load systems.
Key Material Benefits:
- Excellent dry-running capability with minimal wear
- Self-lubricating particles embedded throughout the matrix
- Dynamic surface pressure resistance up to 12 MPa
- Low friction coefficient and high abrasion resistance
- Long-term temperature resistance up to 170°C (HTR17 grade)
- Environmentally friendly: no oil, no risk of marine pollution
Our materials are designed to perform reliably in both dry and water-lubricated conditions, offering a balanced combination of strength, durability, and sustainability.
Water Lubricated Bearings vs. Traditional Lubricated Bearings
Why Water Lubricated Bearings Are the Smarter Choice
When comparing water lubricated bearings with traditional lubricated bearings (such as oil-lubricated or grease-lubricated types), it's clear that water-lubricated systems offer significant advantages in terms of sustainability, cost-efficiency, and system simplicity.
Widely used in marine, hydro, pump, and dredging industries, water lubricated bearings are rapidly replacing conventional lubrication systems in both new designs and retrofit upgrades.
| Feature | Water Lubricated Bearings | Traditional Lubricated Bearings |
| Lubrication Medium | Clean water, seawater, or process water (no oil required) | Oil, grease, or synthetic lubricants |
| Environmental Impact | Eco-friendly, no leakage risk, no oil pollution | Potential oil spills, marine and environmental contamination |
| System Complexity | No oil tanks, piping, or filters needed | Requires oil circulation systems, seals, and pumps |
| Dry Start Capability | Supported with self-lubricating materials | Not recommended, may cause early failure |
| Maintenance Requirements | Minimal maintenance, no oil changes | Regular lubrication checks and servicing needed |
| Service Life | Long service life with wear-resistant materials | Dependent on lubrication quality and seal integrity |
| Cooling Performance | Naturally cooled by the water environment | Requires separate oil cooling systems |
| Application Adaptability | Ideal for seawater, sediment-laden, and eco-sensitive environments | Best for clean, sealed, and controlled environments |
Techemer water lubricated bearings offer a cleaner, more reliable, and more cost-effective solution compared to traditional lubricated bearings, especially in demanding marine and industrial conditions.
