“When the turbine guide bearings installed at several hydroelectric plants in the U.S. suffered short lives and significant wear, the owners turned to lignum vitae material. Their experience has shown that this material, although more costly, can provide longer service life than composite and plastic bearing materials.”
The addition of the Vacuum Pressure Vessel compliments existing processes designed for total saturation to meet and exceed current Marine and Hydro standards.
Total saturation of a water lubricated bearing guarantees 100% reliability of bearing performance required for everything from large to small hydro.
Installation of this vessel has reduced lead times by reliably saturating material in hours and days vs weeks and months. Proper saturation is critical for water lubricated bearings.
This collapsed timeline was proven critical when LVNA was asked to provide 55 thrust and main guide bearings for the 1912 Historic Blewett Falls Hydro Station operated by Duke Energy. LVNA reverse engineered, produced working drawings, manufactured, and delivered in 30 days from PO. These new lignum vitae bearings will continue to produce clean renewable energy for many more decades.

Precautionary measures have been put in place to continue daily production. Our mission compels us to carry on during these extraordinary days.
It’s times like this that causes us to reflect and be grateful.
This week on Mythbusters Lori Ann and James debunk the lignum vitae availability myth. While walking through the shop they uncovered 500 tons of premium bearing grade material. If you thought you could no longer obtain genuine lignum vitae, THINK AGAIN! #hydro #lignumvitae #bearing #thrustbearings #material

- It’s The Air Entrainment
A simple and cost-effective way to address ongoing premature failure, degradation and performance problems in polymers is shifting to lignum vitae bearings and seals.
The no-excuse solution lignum vitae is inherently able to adapt to extreme and dynamic operating environments:
- Zero Clearance
- Run of river water, No Filtering*
- Zero Wiping or Smearing of Material
- High Resistance to Shock, Edge Loading/Vibration issues
- Low Coefficient of Friction
- Oil/Grease-Free Operation
- No Hydrolysis Degradation/perfect memory
- Conforms to Worn Shafts
- Only industrial Renewable Bearing
- Mixed-mode of Lubrication/Dry Start & Hydrodynamic
- First water-lubricated bearing – 1854, the same for centuries
Our team of engineers and specialists collaborates with plant operators to understand their unique challenges to design long-term solutions made with lignum vitae. Contact us to see how the Lignum Vitae North America personalized approach can lead to the superior solution for your needs.
