7. FRETTED SHAFTS & SLEEVES
When shaft scoring occurs. A newly installed Lip Seal riding in same location on shaft will leak.
Water penetrates the bearing immediately…in all cases corrosion is RAPID and Bearing Life is reduced

8. Fretted Shafts & Sleeves
When shaft scoring occurs. A newly installed Lip Seal riding in same location on shaft will leak. A SpediSleve Seal is often used.
While an improvement, the seal eventually fails, water penetrates the bearing immediately…in all cases corrosion is RAPID and Bearing Life is reduced

23. 615 Additive Plating Technology

24. 615 HTG – Technology Overview
Chesterton's 615 is formulated using a surplus of Lubricity, EP and Anti-Wear additives, blended into a highly refined G III base oil, and thickened with a metallic organo-sulfonate complex. The resulting grease is "Best in Class" with respect to EP, Lubricity, Corrosion & Water Resistance.
Unlike conventional Aluminum, Calcium, & Lithium soap and complexed thickeners, Chesterton 615 is immune to hydrolysis or water breakdown. The grease remains functional even in heavy water contaminated bearings and equipment.
Chesterton's 615, with QBT (Quiet Bearing Technology) uses state of the art tribological technology to reduce vibration and ultra-sonic bearing noise. Proprietary polar and non-polar additives and thickener chemically fuse to the metal surfaces filling in asperities to form a "wear shield" on the metal surfaces.
This fusion of lubricating additives and thickeners to the molecular surface of the metal, protects the bearings from WEAR, PRESSURE and WATER CORROSION.
