Benefits of our Bearing:
– The Only Renewable Industrial Bearing
– NSF/ ANSI 61 Certified –Drinking Water System Components
– Long Life • Low Friction • Excellent Startup Ability
– Zero Tolerance –Touches the Shaft
– Zero Pollution • Eliminates Oil or Grease
– Operates in Dirty or Silty Environments
– High Performance & High Edge Load
• Requires zero tolerance – Especially important for older applications with some wear or instability, unlike composite bearings that require inordinate clearance for fear of touching and wiping or smearing the shaft.
• Contains guaiac gum that acts as the lubricant. This water impervious gum glazes the bearing surface, which stays intact for decades, even in dirty or silty water. Unlike other lubricants that are free to flow away from the bearing, guaiac gum is bound in a homogeneous fiber that cannot drain away.
• Contains no abrasives or composites requiring shaft treatments or special coatings.
• Known as the most steel friendly material in use. No moving parts, Nothing to rust or corrode
• Nature’s perfect combination of hardness and lubricity for running against steel.
• Zero wiping or smearing of material onto the shaft, thereby eliminating residual buildup and “thumping.”
• Excellent performance in dirty and silty water, with documented case of 67 years of service on original bearing set in Army Corps of Engineers’ application.
• No need to filter the water or add lubricants required by some composites.
• Easy to install, even when replacing old bearings in remote or crude conditions.
• The only renewable, natural, industrial underwater bearing.
• Requires no grease, oil or other lubricants, which may spill in surrounding water.
• No threat to air, water, or soil, with nothing going into landfill.
• No manufacturing pollution, toxic metals, PCBs, plastic, VOCs, or exotic chemicals.
• The forest is actively managed to preserve the supply of Lignum Vitae into perpetuity through an internationally recognized agency.
