Techemer blank bearing material for vertical pump guide bearings. Water-lubricated, oil-free design with excellent wear resistance, long service life, and reliable performance.
High temperature and high load self-lubricating filament wound bearings for pumps. Oil-free design with strong load capacity, long service life, and reliable performance in harsh conditions.
Techemer water-lubricated radial bearing for turbine guide combines elastic polymer alloy construction with high wear and impact resistance, engineered for durable, oil-free operation in water-lubricated turbine, pump and marine applications. Designed for long service life and reduced maintenance, it supports multiple OEM installation methods.
Techemer TSTN water lubrication bearings are engineered to meet the rigorous demands of modern pump applications. Designed as a long-life and high wear-resistant alternative to Thordon SXL, these bearings run efficiently in fully water-lubricated conditions, eliminating oil lubrication and reducing maintenance while extending service intervals.
Techemer water-lubricated guide bearing bushings are engineered for modern pump systems where continuous water lubrication and long service life are essential. Designed as a reliable replacement for Thordon SXL, these bushings deliver excellent wear and corrosion resistance, low friction performance and extended maintenance intervals across centrifugal, submersible, irrigation and industrial pumps. The advanced elastomeric polymer alloy material ensures stable shaft support and reduced downtime in demanding operating environments.
A shaft thrust bearing is essential for controlling axial loads in vertical and propeller shaft systems. Techemer water-lubricated thrust bearings offer low friction, stable load capacity, and long service life for demanding applications.
Techemer maintenance-free ceramic bearing bushings provide advanced water-lubricated, self-lubricating solutions for mining equipment and heavy duty pumps challenged by abrasive slurry, corrosion and high temperature. Made with ultra-hard silicon carbide ceramics and engineered elastomer cushioning, these bushings deliver long service life, low maintenance and customizable fit for demanding industrial environments.
Techemer water-lubricated marine rudder and stern tube bearings engineered to replace Thordon bushings. Superior wear resistance, long service life and reliable performance for modern vessels.
Techemer water-lubricated stern tube bearings are ISO certified and engineered to deliver an extended service life and reliable performance in marine stern tube applications. Designed as equivalent replacements for Thordon bushings, these water-lubricated bearings exhibit superior wear and corrosion resistance, high load capacity, and low maintenance requirements, supporting cleaner vessel operation and longer maintenance intervals.
Techemer self-lubricating fore & stern tube marine bearings are engineered with an advanced elastomeric polymer alloy, providing superior wear resistance, low friction, and long service life under water-lubricated conditions. Designed to replace traditional Thordon SXL stern tube and rudder bearings, they offer environmental benefits, dry start capability, and reduced maintenance — making them ideal for bulk carriers, working vessels, yachts and deck machinery.
It provides rotational support, reduces friction during vane movement, and protects the shaft neck from wear. Traditional copper-based graphite mosaic bearings have long served this purpose — but Techemer non-metallic guide vane sleeves offer a superior alternative.

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.
