FAG Bearing NJ1048-M1

Product description of FAG Bearing NJ1048-M1

Cylindrical roller bearings have a single or multiple row rolling element set based on cylindrical rollers. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. As a result, it can transmit higher forces, has greater rigidity and allows smaller rolling element diameters under the same load.

Depending on the design of the ribs on the bearing rings: axial forces can be supported in one or both directions axial displacements of the shaft relative to the housing are compensated without constraint in the bearing (in bearings with a semi-locating or non-locating bearing function) the bearings can be separated for easier mounting.

FAG Bearing NJ1048-M1, Cylindrical roller bearings are available in various designs, the characteristics of which are optimized for different applications depending on the structure of the bearings: The bearings are available in a single or double row design, with different combinations of ribs on the inner and outer ring, a full complement cylindrical roller set and with various cage designs.

FAG Bearing NJ1048-M1, ,Single row cylindrical roller bearings with cage are suitable where: • Bearing arrangements are subjected to very high radial loads • Not only high radial forces but also axial loads from one or both directions must be supported by the bearing position (semi-locating or locating bearing function) • Bearing arrangements must have very high rigidity • Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing (in the case of bearings with a non-locating or semi-locating bearing function) • High radial loads and very high speeds occur but the very high radial load carrying capacity of full complement cylindrical roller bearings is not required • The bearings should be separable (one bearing ring can be removed for easier mounting) • Cylindrical roller bearing with cage/full complement bearing, comparison of speed and load carrying capacity nG = limiting speed Cr = basic dynamic load rating SL1923 = full complement cylindrical roller bearing NJ23 = cylindrical roller bearing with cage

Cylindrical roller bearings with disc cage/with spacers are suitable where: • Bearing arrangements are subjected to very high radial loads and higher speeds occur • High dynamic inertia forces are present • Not only high radial forces but also axial loads from one direction must be supported by the bearing position (semi-locating bearing function) • High shock loads occur • Thermally stable conditions are required in the bearing even at higher speeds • The cages are subjected to high dynamic inertia forces; e. g. in vibratory machinery • Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing • The bearings should be separable for easier mounting; in vibratory machinery, for example, the bearing ring with circumferential load as well as the ring with point load should have a tight fit Cylindrical roller bearing with full complement bearing/standard cage/disc cage, comparison of speed and load carrying capacity nG = limiting speed Cr = basic dynamic load rating SL1923 = full complement cylindrical roller bearing NJ23 = cylindrical roller bearing with standard cage LSL1923 = cylindrical roller bearing with disc cage

FAG Bearing NJ1048-M1, Single row full complement cylindrical roller bearings are suitable where: • Bearing arrangements are subjected to particularly high radial loads • Not only very high radial forces but also high axial loads from one direction must be supported by the bearing position (semi locating bearing function) • Bearing arrangements operating under the conditions described above must have very high rigidity • Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing • Very high radial loads occur at lower speeds, i. e. the bearings do not need to achieve speeds as high as those of cylindrical roller bearings with cage • Particularly space-saving designs are required despite very high load • The bearings should be separable (not self-retaining) for easier mounting Cylindrical roller bearing with cage/full complement bearing, comparison of speed and load carrying capacity Cr = basic dynamic load rating nG = limiting speed

FAG Bearing NJ1048-M1,Double row full complement cylindrical roller bearings are suitable where: • Bearing arrangements are subjected to particularly high radial loads • Not only particularly high radial forces but also axial loads from one or both directions must be supported by the bearing position (semi-locating or locating bearing function) • Bearing arrangements must have very high rigidity • Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing (in the case of bearings with a non-locating or semi-locating bearing function) • Very high radial loads occur at lower speeds, i. e., the bearings do not need to achieve speeds as high as those of cylindrical roller bearings with cage • Space-saving designs are required despite very high load • The bearings should be separable for easier mounting (bearings with non-locating bearing function) bearing with cage/single row full complement bearing, double row full complement bearing, comparison of speed and load carrying capacity Cr = basic dynamic load rating nG = limiting speed
