The storage area temperature should be maintained between 0 C (32 F) and 40 C (104 F); temperature fluctuations should be minimized. The relative humidity should be maintained below 60 percent and the surfaces should be dry. The storage area should be kept free from airborne contaminants such as, but not limited to, dust, dirt, harmful vapors, etc. The storage area should be isolated from undue vibration. Extreme conditions of any kind should be avoided. Due to the fact that Timken is not familiar with your particular storage conditions, we strongly suggest following these guidelines. However, you may be required by circumstances or applicable government requirements to adhere to stricter storage requirements. Most bearing components typically ship protected with a corrosion-preventive compound that is not a lubricant. These components may be used in oil-lubricated applications without removal of the corrosion-preventive compound. When using some specialized grease lubrications, we advise you to remove the corrosion-preventive compound before packing the bearing components with suitable grease. We pre-pack most housed unit types in this catalog with general-purpose grease suitable for their normal applications. It may be necessary for you to frequently replenish the grease for optimum performance. Be careful in selecting lubrication, however, since different lubricants are often incompatible. You may order housed units pre-lubricated with a specified lubrication. When you receive a bearing or housed unit shipment, do not remove products from their packaging until they are ready for mounting so they do not become corroded or contaminated. Store bearings and housed units in an appropriate atmosphere so they remain protected for the intended period.
