Do Timken® bearings come pre-lubricated?
Most Timken bearings are protected with a thin film preservative that, although excellent at preventing rust and corrosion, is not a lubricant. Because our preservative is compatible with most oils and greases, it is not necessary to clean the preservative off prior to adding lubricant. Timken also produces a wide range of special package bearing units that are “pre-lubricated” at the factory. These include “AP” Railroad bearings, automotive hub assemblies, housed units, wide inner ring ball bearings, pillow block units and some ball bearings. Because these units are pre-lubricated, it is not necessary to remove seals to add any additional grease.
