OneDrop™ Ball Bearing Conditioner and Lubricant is designed to be used on traveler cars and other ball-bearing applications to improve performance by reducing rolling friction. OneDrop Ball Bearing Conditioner is the only product that Harken recommends for use on ball-bearing travelers and battcars.
Only one drop of this new conditioner will repel salt, dirt, and other deposits to protect, lubricate, and condition the bearing surfaces. Reduced friction allows balls to roll freely and evenly, greatly improving traveler performance. McLube™ is a registered trademark of McGee Industries, Inc.
