1 E1 Spherical Roller Bearings The new standard for performance and operational reliability

2 FAG s innovative E1 spherical roller bearing provides increased reliability, greater economic efficiency, and superior performance. Backed by 90 years of FAG field research and supported by the latest developments in kinematics, material sciences and manufacturing processes, the E1 outdistances the competition with extended life owing to its superior design and technology. With the E1, FAG has set the new standard for spherical roller bearings. Superior performance for the same price. FAG E1 spherical roller bearings are universally suited to virtually any industry. Whether exposed to high radial or axial loads, unbalanced forces, vibration stress, high speeds, angular misalignment or constant high temperature E1 bearings from FAG are designed to rise to the conditions to keep machinery operating. Characteristics E1 spherical roller bearings are made for heavy-duty applications. They feature two rows of syetrical barrel rollers, which can align freely in the spherical outer ring raceway, thus compensating for shaft deflections and misalignment of the bearing seats. Unlike other spherical roller bearings, these bearings have no center lip on the inner ring, allowing for a maximum number of longer rollers with a large diameter. The close contact between the rollers and raceways yields a uniform stress FAG. 2 distribution, and the optimization of roller size permits distinctly higher load carrying capacity than conventional spherical roller bearings. A Large Range The FAG E1 program consists of 100 basic types spanning eight spherical roller bearing series, for shafts ranging from 20 to 200. FAG E1 spherical roller bearings are available with either a cylindrical or a tapered bore. Spherical roller bearings with a tapered bore are mounted onto a shaft with an adapter or withdrawal sleeve. For particularly punishing operations where vibratory stressing must be accoodated, FAG offers special design E1 bearings with narrow tolerances and increased radial clearance (suffix T41A). Design Features The basic design of FAG E1 spherical roller bearings incorporates the following standard features: normal tolerances of radial bearings (special design T41A with narrow tolerances) normal clearance, with increased radial clearance (C3, C4) available on request a lubricating groove and three lubricating holes in the outer ring (except sizes to 21307E1TVPB) S1 heat treatment for operation at temperatures as high as 200 C or 392 F cylindrical or tapered bore

3 Standard Cages Depending upon the bearing series and size, FAG E1 spherical roller bearings are equipped with either a pressed steel, machined brass, or molded polyamide cage. In many instances, the choice between two of the three is available. Series 222E1 and 223E1, from 25 to 180 bore, are available with a two piece, pressed steel cage (no suffix). The cage is outer ring riding, supported by a metallic guide ring in the outer ring. For highest possible wear resistance, a roller riding machined brass cage (suffix M) is available for most sizes in most series. Standard Cages for FAG E1 Spherical Roller Bearings Pressed Steel Machined Brass Molded Polyamide outer ring guided roller riding inner ring guided (suffix M) (suffix TVPB) Series Bore Reference 213E1 up to E1 up to 36 up to E1 up to 30 up to E1 up to E1 up to E1 up to E1 up to E1 up to 28 Advantages The considerably higher load carrying capacities and inherently lower bearing temperatures of FAG E1 spherical roller bearings promote increased operational reliability and a longer service life. In newly built machines, smaller bearings match the performance of previously used larger bearings. This permits downsizing and consequently a more costefficient bearing with less friction, less lubricant consumption and higher speeds. FAG. 3
