FAG B70..-TVP-P4 series spindle bearings

FAG spindle bearings are manufactured under the highest cleanliness conditions and using state-of-the-art washing technologies. Furthermore, their quality is assured by means of 100% “end-ofline” noise testing.

Due to the cleanliness conditions and the preservation methods and agents applied, they can be directly greased and mounted by the end user without the need for additional intermediate cleaning processes. The use of cages guided by the rolling elements in FAG spindle bearings with the suffix P4 allows an increase of up to 30% in the speed of grease distribution.

FAG Spindle bearings with numerous advantages

  • higher limiting speeds compared to competitor products
  • rapid availability
  • minimal noise
  • efficient in mounting and commissioning
  • new ball-guided polyamide cage TVP
  • data matrix code on the bearing: high level of security against counterfeit bearings
  • marking of the width tolerance on the bearing and the packaging
  • available in numerous sizes: from d=25mm to d=100mm
  • for high continuous loads.

Areas of application

  • milling spindles in the medium speed range
  • main spindles with external drive
  • spindles in machining centres
  • high speed electric motors.
