You can see your Timken engineer for more information. 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. 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 migration, operating conditions, installation conditions, temperature, humidity and extended storage.

Shelf life values, available from Timken, represent a maximum limit and assume adherence to the Timken suggested storage and handling guidelines.

Deviations from Timkens storage and handling guidelines may reduce shelf life. Any specification or operating practice that defines a shorter shelf life should be used. Timken cannot anticipate the performance of the grease lubricant after the bearing or component is installed or placed in service. For further information, please contact your Timken engineer.

Timken suggests the following storage guidelines for its finished products bearings, components and assemblies, hereinafter referred to as Products : kept in their original packaging until they are ready to be placed into service. Products should be stored in such a way that the packaging is not pierced, crushed or otherwise damaged. After a Product is removed from its packaging, it should be placed into service as soon as possible.

Do not use Product that has exceeded its shelf life as defined in Timkens shelf life guidelines statement. The storage area temperature should be maintained between 0 C 32 F and 40 C 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 isolated from undue vibration. Extreme conditions of any kind should be avoided. Inasmuch as Timken is not familiar with a customers particular storage conditions, these guidelines are strongly suggested. However, the customer may very well be required by circumstance or applicable government requirements to adhere to stricter storage requirements.

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 be exercised in lubricant selection, however, since different lubricants are often incompatible.

When specified by the customer, other bearings may be ordered pre-lubricated. Upon receipt of a bearing shipment, ensure that the bearings are not removed from their packaging until they are ready for mounting so that they do not become corroded or contaminated.

Bearings should be stored in an appropriate atmosphere in order that they remain protected for the intended period. Failure to observe the following warnings could create a risk of death or serious injury. Proper maintenance and handling practices are critical. Always follow installation instructions and maintain proper lubrication.

Never spin a bearing with compressed air. The rollers may be forcefully expelled. Warnings for this product line are found in this catalog and posted on www. Any questions concerning shelf life or storage should be directed to your local sales office.

Our tapered roller bearings stand up to extreme situations, including high-corrosive, high-temperature, vacuum or lowlubrication environments.

Use Timken tapered roller bearings to help your equipment excel when it faces combined radial and thrust loads. Our bearings are uniquely designed to manage both types of loads on rotating shafts and in housings.

From single- to double- to four-row configurations to thrust, choose from nearly 26, product combinations to find the right bearing for your application. Design Features Each tapered roller bearing contains four interdependent components: the cone inner ring , the cup outer ring , tapered rollers rolling elements and the cage roller retainer.

Tapered angles allow our bearings to efficiently control a combination of radial and thrust loads. The steeper the outer ring angle, the greater ability the bearing has to handle thrust loads.

To provide a true rolling motion of the rollers on the raceways, the extensions of the raceways and the tapered surfaces of the rollers come together at a common point, the apex, on the axis of rotation. Product Offering We have the most extensive line of tapered roller bearings available anywhere in the world. Single-, double-, four-row and thrust options are available in sizes ranging from 8 mm 0.
