FAG Spindle Bearings （Precision Bearings）

FAG Spindle Bearings(Sealed Spindle Bearings):

Sealed Spindle Bearings Spindle bearings are high precision functional parts that react sensi tively to damaging influences from the environment such as contamination and airflows. Proper greasing in terms of the amount and selection of lubricant is also a criterion that can directly affect machine service life, as the grease service life is in effect equal to the bearing service life. Early on, FAG set the standard for High Speed Spindle Bearings (HSS, HCS and XCS) with sealed bearings. Almost all spindle bearings are now offered with non-contact gap seals on both sides, as their special sealing advantages have gained acceptance on the market. Sealed FAG Spindle Bearings are filled with FAG ARCANOL L075 high performance grease and combine many advantages: • robust, compact unit • ready-to-fit, lubricated for-life, maintenance-free • factory-filled with optimum grease in the appropriate quantity • protected against contamination and airflow The wide range of applications for Sealed Spindle Bearings also marks the continuing trend from oil lubrication to grease lubrication. High Speed versions of FAG Sealed Spindle Bearings bear the abbrevia tion S (for Sealed) in their classification. Large-ball bearings, such as bearings of the B prefix, carry the designation 2RSD in their name.

Direct Lube Bearings:
 Where grease lubrication meets its limits, FAG Direct Lube (DLR) Bearings ideally complement the Spindle Bearing range. Direct Lube Bearings ensure reliable lubricant feed very close to the point of rolling contact. This is achieved by a  circumferential groove and radial supply holes. Integral precision O-rings seal the bearing against the spindle housing. FAG DLR Bearings reach extremely high speeds. The exceptional power density of this bearing design is not its only advantage. The design allows for the elimination of costly elements in the surrounding structure. The result is savings in both space and cost.
