Customization Water lubricated Bearing Solutions for your project
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.
♦ 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
♦ 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.

Why INDRON® Water-Lubricated Bearings Outperform THORDON？
When selecting a water-lubricated bearing, long service life, low wear, and stable performance under harsh marine conditions are critical. Independent test data from GB/T 9867, ISO 4649, and ASTM D5963 reveals a clear pattern: INDRON® engineered elastomer-alloy composites consistently exhibit lower wear volume than many common non-metallic materials—including several THORDON grades.
1.Lower Wear, Longer Life — Proven by Data
Under identical test conditions, several INDRON® materials rank among the lowest wear values:
GB/T 9867, ISO 4649 and ASTM D5963 Relative Volume Wears Comparison (m³)
Part of the data is abstracted from Thordon's Product Specifications
ASTM D5963 (Comparison of abrasion) (㎥)
Partial data from THORDON product description
Under the same conditions, INDRON® elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON® bearing has longer service life, higher reliability and lower maintenance cost.
INDRON hRBR and TITN exhibit lower wear than THORDON XL, SXL, HPSXL, and THORPLAS.
This means longer bearing life, reduced downtime, and significantly lower total operating cost.
2.Engineered for Harsh Marine Environments
INDRON® materials combine elastomer-alloy composite technology with high resilience and dimensional stability, offering:
● Superior resistance to abrasion from sand, silt, and debris
● Lower friction for cooler, quieter operation
● Excellent compatibility with water-lubricated systems
● Stable performance under high load and shaft misalignmen
● Many users report longer in-service intervals when replacing traditional non-metallic bearings with INDRON®.
3.Cost Savings Without Compromising Reliability
Because wear volume is directly linked to bearing lifespan, INDRON®'s lower wear data translates into:
● Longer replacement cycles
● Reduced maintenance labor and costs
● Lower shaft wear
● More stable performance for propeller shafts, stern tube systems, rudders, and pumps
In real marine applications—bulk carriers, workboats, fishing vessels, and tidal/wave-energy units—INDRON® bearings have repeatedly demonstrated longer life and reduced operational disruptions.
