SHELF LIFE AND STORAGE To help you get the most value from our products, Timken provides guidelines for the shelf life of grease-lubricated ball and roller bearings, components and assemblies . Shelf life information is based on Timken and industry test data and experience . SHELF LIFE Shelf life should be distinguished from lubricated bearing/ component design life as follows: Shelf life of the grease-lubricated bearing/component represents the period of time prior to use or installation . The shelf life is a portion of the anticipated aggregate design life . It is impossible to accurately predict...

A WARNING 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 . Tensile stresses can be very high in tightly fitted bearing components . Attempting to remove such components by cutting the cone (inner race) may result in a sudden shattering of the component, causing fragments of metal to be forcefully expelled. Always use properly guarded presses or bearing pullers to remove bearings from shafts, and always use suitable personal...

ENGINEERING SIZE RANGE • TYPES • CONFIGURATIONS SIZE RANGE Deep groove ball bearings are available in a variety of sizes and are the most popular of the rolling bearings. This type of bearing supports radial load and a small degree of axial load in both directions simultaneously. Deep groove ball bearings are popular due to their versatility, affordability, and capability to run at high speeds. Variations may differ based on bearing size and/or series. Timken offers deep groove ball bearings in a wide range of sizes and configurations. Offered sizes range from 3 mm toB400 mm BR bore, and maximum...

CAGES CAGES Cages (also referred to as retainers) make a vital contribution to overall bearing performance . They maintain uniform ball spacing in the bearing as the balls pass into and out of the load zone . Cages can impact several bearing operational characteristics such as: • Maximum rotational speed • Torque characteristics • Temperature limits • Lubricant flow There are a number of different cage types that are commonly used in deep groove ball bearings, the most popular being the riveted steel cage . Table 1 describes the most common cage types . TABLE 1. COMMON CAGE TYPES TIMKEN® DEEP...

BEARING SHIELDS AND SEALS Bearing shields and seals help keep lubricant in and dust, water and other contaminants out . Timken shielded deep groove ball bearings are available with one or two shields for coarse debris . Single shielded bearings allow for re-lubrication from the open side . Sealed ball bearings are available with one or two seals for improved protection in harsh environments . Offered in contact or non-contact configurations, Timken seals use high-performance Nitrile Buna Rubber with reinforced low-carbon steel case for standard operating temperatures . The following table summarizes...

BEARING LUBRICATION BEARING LUBRICATION Bearings must be lubricated to minimize friction between balls and raceways, as well as between balls and cages . Lubricants also help to protect the bearings from corrosion and, in some cases, to dissipate heat . Timken open ball bearings, as well as single-sealed/shielded bearings, are supplied with rust preventive (RP) covering all bearing surfaces . For such bearings, the end user selects and applies the desired lubrication type and quantity as required by the application . Timken double-sealed and double-shielded deep groove ball bearings are factory...
