2344 23478: Mounting ends of double direction angular contact thrust ball bearings of series 2344 and 2347 inrelation to double row cylindrical roller bearingsLubricationFAG angular contact thrust ballbearings can be lubricated eitherwith grease or oil.Their housing washers feature a lubricatinggroove and lubricatingholes at the centre. The lubricantsupply between the two rows ofballs utilizes the conveying effectof the bearing. For this reason thebearings require a considerablygreater amount of oil than a possiblyadjacent cylindrical roller bearing.At the design stage, attentionshould therefore be paid to the factthat this oil flow should not all goto the cylindrical roller bearings.FAG · 103
