SHELF LIFE AND STORAGE Timken guidelines for the shelf life of grease-lubricated rolling bearings, components and assemblies are set forth below. Shelf life information is based on test data and experience. Shelf life should be distinguished from lubricated bearing/ component design life as follows: SHELF LIFE POLICY Shelf life of the grease-lubricated bearing/component represents the period of time priorto use or installation. The shelf life is a portion of the anticipated aggregate design life. It is impossible to accurately predict design life due to variations in lubricant bleed rates, oil...

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 prepacked with general purpose grease suitable for their normal application. Frequent replenishment of the grease may be necessary for optimum performance. Care must...
