What types of bearings can be used underwater?

Underwater bearings are specialized components designed to withstand the unique challenges posed by submersion in water, including corrosion and lubrication issues. Selecting the right bearing material ensures longevity and performance in underwater applications.

Types of Bearings Suitable for Underwater Use

• Ceramic Bearings:

Made from materials like zirconium dioxide or silicon nitride.

Completely unaffected by seawater and can operate under high loads even when permanently submerged.

• Plastic Bearings:

Highly corrosion-resistant and effective in both freshwater and saltwater environments.

Generally more cost-effective but have lower load capacities compared to metal or ceramic options.

• 316 Stainless Steel Bearings:

Good for temporary submersion; they require a regular flow of water to prevent corrosion.

Suitable for low-load applications in freshwater environments but less effective when continuously submerged in saltwater without adequate water flow.

• Carbon/Graphite Bearings:

Ideal for submerged applications involving low viscosity liquids.

They do not suffer from the same atomic attraction issues as metal bearings, allowing for effective lubrication even with minimal liquid film.

• Hybrid and Coated Bearings:

These include hybrid bearings and Aqua-Bearings, which are designed to withstand moist environments and can handle various chemical exposures.
