TIMKEN Overview Most bearing types are typically shipped protected with a corrosionpreventive compound that is not a lubricant. Such bearings may be used in oil-lubricated applications without removal of the corrosionpreventive compound. When using some specialized grease lubrications, it is advisable to remove the corrosion-preventive compound before packing the bearings with suitable grease. Some bearing types in this catalog are pre-packed with general purpose grease suitable for their normal application. Frequent replenishment of the grease may be necessary for optimum performance. Care must...
