Vertical Turbine Bearings
Composite - GM2401
The Composite GM2401 is built for very abrasive water environments, offering twice the abrasion resistance and lower friction than rubber. Its water-lubricated, grease-free design ensures easy installation and minimal maintenance downtime.
ThorPlas - White
ThorPlas-White is ideal for food equipment and potable water applications, with NSF/ANSI and WRAS approvals. It features low friction, minimal wear, and excellent dry run capability thanks to built-in lubricants. Easy to machine and install, it ensures reliable performance and compliance.
ThorPlas - Blue
ThorPlas-Blue is an engineered thermoplastic designed for high-pressure applications, with dry start-up capability and operation in water and chemicals up to 80°C (176°F). It offers excellent performance under pressures up to 45 MPa and ensures low wear in non-abrasive environments.
Thordon XL
Thordon XL is designed for clean water applications, offering long life, low dry friction, and good abrasion resistance. It ensures reliable performance and durability in demanding environments.
Thordon SXL
Thordon SXL is ideal for dry start-up applications, offering a low dry friction coefficient and operation in wet or dry conditions. It handles pressures up to 10 MPa and provides excellent resistance to abrasion, shock loading, and vibration.
Marine Bearings
Thordon Blue Ocean Stern Space
The T-BOSS (Thordon-Blue Ocean Stern Space) is a groundbreaking sterntube-less propeller shaft system that eliminates the need for oil-lubricated bearings, using Thordon’s seawater-lubricated COMPAC system instead. This design enables inspection and maintenance while the ship is afloat, reducing downtime and eliminating costly dry-docking for shaft-related repairs. By replacing lubricating oil with seawater, T-BOSS significantly cuts operational costs and environmental risks. With a lifetime bearing wear guarantee, it offers unmatched reliability and long-term savings for shipowners.
