Techemer - Water-Lubricated Bearings & Shaft Seals Manufacturer Since 2008 — ISO-Certified | Fully Patented
Ceramic Bearing for Water Pump
Techemer Composites (Guangdong) Co., Ltd., under the INDRON® brand, is a leading developer and manufacturer of high-performance ceramic bearing water pump systems. Our bearings are engineered for long-term operation in harsh water environments — from seawater circulation and cooling pumps to high-temperature chemical process pumps.
INDRON® ceramic bearings for water combine precision ceramic materials with advanced damping structures, offering superior wear resistance, corrosion protection, and dimensional stability where traditional metal bearings fail.
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 INDRON® Ceramic Bearings Different？
Traditional ceramic bearings are often limited by brittleness and installation sensitivity. INDRON®’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.
Ceramic Bearings Material Performance Comparison
| Feature | INDRON® Ceramic Bearing | Metal Bearing | Polymer Bearing |
| Lubrication | Water / liquid medium | Oil / grease | Water / mixed |
| Wear Resistance | Excellent, >30,000 hrs | Medium | Moderate |
| Corrosion Resistance | Outstanding (SiC + WC) | Poor | Fair |
| Temperature Limit | 900–1500°C | 300°C | 120°C |
| Maintenance | Minimal | Frequent oil replacement | Periodic |

INDRON® ceramic bearings extend equipment life, reduce unplanned downtime, and lower total maintenance cost — the smarter choice for long-term reliability.
Engineering Design Highlights
The INDRON® ceramic bearing pump design integrates practical mechanical engineering with material science excellence:
- Inclined locking surfaces prevent ceramic cracking caused by thermal expansion.
- Circular cooling channels around the ceramic liner provide continuous liquid flow and enhanced heat dissipation.
- Double-layer shaft sleeve improves friction pair lubrication and dimensional fit in dynamic water conditions.
- Non-rotating end structure with stepped press-fit ensures long-term stability under axial load.
These design elements extend bearing life and maintain stable operation even in systems with high sediment or vibration.

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 |
INDRON® 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.
