OneDrop Ball Bearing Conditioner is the only product that Harken recommends for use on ball bearing travelers and battcars to repel salt and dirt, and to protect, lubricate and condition the surface of the ball bearings, reducing friction and allowing the ball-bearings to roll freely and evenly.
Use OneDrop instead of dry-lubricant aerosols, which can result in ball bearings sliding rather than rolling, causing flat-spotting and subsequent failure of your blocks and cars.
