Developed through years of research and on-site testing, Techemer ceramic bearings for water offer a stable and energy-efficient alternative to traditional metal bearings, perfectly suited for seawater circulation, cooling systems, and chemical process pumps.
With self-lubricating performance, excellent dimensional stability, and zero oil contamination, our ceramic bearings ensure reliable operation even in harsh water conditions.
Techemer's TSTN water-lubricated composite bearing material is engineered for demanding pump and marine applications and serves as a high-performance alternative to Thordon SXL. Carefully formulated with self-lubricating microcrystals and extreme pressure particles, TSTN offers low friction, high wear resistance, and reliable dry-start performance. Its PV capability of up to 100 MPa·m/s under water lubrication and resistance to adhesive wear make it ideal for critical guide bearings, thrust bearings, and bushings in heavy-duty environments.
Techemer high-temperature ceramic bearings are engineered using advanced silicon carbide (SiC) ceramics and innovative structural designs to meet the demands of extreme industrial environments.
Techemer ceramic guide bushings are engineered for marine, industrial, and renewable energy applications, offering superior wear resistance, corrosion protection, and maintenance-free performance.
Techemer ceramic bushing bearing for water pumps offers cutting-edge performance, corrosion resistance, and unmatched longevity.
Ceramic bushing with stainless steel housing for pumps. High temperature resistant, water-lubricated plain bearing with excellent wear and corrosion resistance, long service life and low maintenance.
Techemer ceramic bearings for hydro-turbine engineered for oil-free, water-lubricated operation. Designed for demanding hydro turbine and pump systems, these ceramic bearings provide excellent wear resistance, corrosion protection, and long service life while reducing maintenance and operating costs.
Techemer ceramic bearing technology is at the forefront of the industry, widely recognized for its exceptional wear and corrosion resistance in mining and chemical applications.

What Is a Ceramic Bearing for Water Pumps?
A ceramic bearing water pump uses high-hardness, corrosion-resistant ceramics (such as silicon carbide or silicon nitride) as the core material for its bearing components. These materials can run directly in water without any oil or grease lubrication — making them ideal for clean, eco-friendly, and maintenance-free operation.
What Makes Techemer Ceramic Bearings Different？
Traditional ceramic bearings are often limited by brittleness and installation sensitivity. Techemer's unique composite design overcomes these weaknesses through an integrated three-layer structure:
- Ceramic Bushing (SiC): High-hardness silicon carbide with outstanding corrosion resistance and wear strength.
- Dual-Metal Shaft Sleeve: Stainless steel with a tungsten carbide coating for excellent friction performance in water.
- Elastic Buffer Layer: German NDI engineering elastomer that absorbs vibration, reduces misalignment stress, and supports dry starts.
This innovative design allows ceramic bearings in water to perform smoothly under high load, high temperature, and high vibration conditions — achieving true “oil-free” operation without sacrificing durability.
Key Technical Advantages
- High Hardness & Wear Resistance: SiC ceramics reach HRC75–80, maintaining precision even under abrasive water flow.
- Corrosion Resistance: Proven performance in seawater, acids, and alkalis; weight loss under 0.2 mg/cm²/year in tests at 100°C
- Thermal Stability: Operates reliably at temperatures up to 1500°C (SiC) and 900°C (tungsten carbide)
- Self-Lubricating in Water: Maintains low friction without oil or grease, ideal for environmentally sensitive systems.
Each Techemer ceramic bearing consists of a high-hardness ceramic bushing, reinforced metal-ceramic shaft sleeve, and a flexible elastomer layer that absorbs vibration and protects the shaft from micro-abrasion.

FAQ - Ceramic Bearing for Water Pump
1
Why use ceramic bearings in water pumps?
Ceramic pump bearings are used because they offer several advantages over metal bearings:
- · Excellent corrosion resistance · Higher hardness and wear resistance
- · Lower friction and energy loss
- · Longer service life
- · Oil-free operation
These features make ceramic bearings ideal for industrial, marine, and chemical pump systems.
2
Are ceramic pump bearings better than metal bearings?
In many water-based environments, ceramic bearings outperform metal bearings because they do not rust and maintain performance under abrasive or corrosive conditions. Their low friction and high durability also reduce maintenance and downtime.
3
Can ceramic bearings run without lubrication?
Yes. Ceramic bearings can operate using water or process fluid lubrication, eliminating the need for oil or grease. This makes them ideal for environmentally sensitive applications and clean industrial systems.
