Reducing energy consumption in refrigeration compressors by up to 5%, the new FAG axial ball bearings from The Schaeffler Group are available in four types, which can be freely combined. Both bearing washers can be supplied with or without raceways. Bearing cages are supplied in either sheet steel or plastic, matched to the operating environment. The sheet steel cage has a special “filigree” (twisted wire) design, which not only provides high rigidity, but is even more suitable than plastic cages for the high temperatures that occur in these bearing positions. The bearing materials are highly compatible with coolants and are resistant to varying temperatures. The raceways in the axial washers provide secure guidance for the balls and improve load distribution and ball rotation. Overall, these characteristics result in a reduced wear and which a longer operating life. Bearings with raceways on both sides are also available, which provide increased mounting security. In the basic design, the axial bearing washers are punched, through-hardened and polished, and both sides can be used as raceways. The size of the bearing can be adapted to suit individual mounting locations. Specifically matched to eccentric shaft bearings in refrigeration compressors, the rolling bearings replace the plain bearings that are normally used in these mounting positions.
