Product description of FAG Bearing 29388-E1-XL-MB

FAG Bearing 29388-E1-XL-MB,Category: FAG Bearing > Rolling and Plain Bearings > Roller Bearings > Axial Spherical Roller Bearings

Axial spherical roller bearings are single row units comprising a shaft locating washer, housing locating washer and asymmetrical barrel rollers with cages. The cage holds the roller and cage assembly and the shaft locating washer together. The bearings can be dismantled. As a result, the bearing components can be fitted separately.

Axial spherical roller bearings can support very high axial loads and allow relatively high speeds. Since the raceways are inclined relative to the bearing axis, the bearings can also support radial loads.

Due to the geometry of the rolling elements and raceway, axial spherical roller bearings feature angular adjust-ability, which can compensate for shaft deflections and misalignment of the bearing seats.

Further key features in addition to angular adjust-ability are the high radial and very high axial load carrying capacity, even in the presence of shock type loads. Axial spherical roller bearings are suitable where:

bearing arrangements are subjected to high and very high axial loads
dynamic or static misalignment of the shaft relative to the housing, or deflections of the shaft, must be compensated by the bearing under axial loads
radial forces occur in addition to axial forces (maximum 55% of Fa)
a relatively high speed suitability is required in addition to a high load carrying capacity
high shock type loads must be supported
bearing parts are to be mounted separately (the bearings are not self retaining)

Axial spherical roller bearings are single-row roller bearings with an angular adjustment facility. They comprise solid shaft and housing locating washers and asymmetrical barrel rollers with cages. The cage holds the roller and cage assembly and the shaft locating washer together. The bearings can be dismantled. As a result, the bearing components can be fitted separately.

FAG Bearing 29388-E1-XL-MB, Axial spherical roller bearings can support very high axial loads and enable relatively high speeds. Both under the harshest of operating conditions. For example in gearboxes, calenders, engines in marine applications and rudder engines, lifting gear, construction machinery and rolling mills.

FAG Bearing 29388-E1-XL-MB, Axial spherical roller bearings, have two rows of symmetrical rollers, a common spheres outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. They are designed to accommodate heavy radial loads, combined with or without axial loads in both directions. The bearings are suited for both locating as well as non-locating bearing positions of shafts. Their split design makes them beneficial for inaccessible applications where mounting, dismounting and maintenance is a challenge. The split spherical roller bearings can be used in a number of different heavy-duty industries such as Mining, Mineral Processing and Cement.
