Tapered Roller Bearings

Product Details:

Features Operating conditions for bearings in vibratory machinery Vibratory screens used for grading, in other words the separation of solid materials according to grain size and other vibratory machinery such as road rollers and saw frames are among the machines subjected to the most severe stresses. The rolling bearings fitted in the exciter units of these machines must support not only high loads and high speeds but also accelerations and centrifugal forces. In many cases, these applications involve adverse environmental conditions such as contaminated environments and excessive moisture. The special spherical roller bearings developed by FAG are matched to the operating conditions in vibratory machinery and have proved highly successful in practical use. In particular, the cages of the rolling bearings are subjected to stresses arising from high radial accelerations. In unfavourable cases, these may be overlaid by axial accelerations as well. The rotating imbalance generates rotating shaft deflection and additional sliding motion within the bearings. This increases the friction and therefore the operating temperature of the bearings. FAG special spherical roller bearings can support dynamic angular misalignments of up to 0,15°. For larger misalignments, please consult Application Engineering at Schaeffler.Basic designs of FAG special spherical roller bearings FAG special spherical roller bearings for vibratory machinery have main dimensions corresponding to dimension series 23 (DIN EN 616:1995-01, ISO 15). For the particular stresses occurring in vibratory machinery, we manufacture all the special spherical roller bearings described in this publication in accordance with specification T41A or T41D, see page 5. Very high load carrying capacity is achieved through optimum use of bearing cross-section as a result of further development of spherical roller bearings of series 223..-E1-XL in X-life quality.

Product Details:

A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
