FAG special spherical roller bearings with Durotect® CK coating have been developed with vibratory machinery applications in-mind. The special hard chromium coating contributes to reducing friction and wear, also protecting against displacement as a result of thermal influences.


  • Able to withstand the severe stresses of vibratory machinery.
  • The Durotect® CK coating is applied to the bore, and prevents the common issue of fretting corrosion between the bearing bore and the shaft.
  • Dimensions and tolerances comply with DIN/ISO dimensions, allowing for easier replacement/interchange.
  • Capable of supporting high loads.
  • Can compensate misalignment.
  • Various sizes also available in the premium X-life quality, delivering higher performance levels and an extended service life.
  • X-life bearings are marked by the "XL" suffix in the bearing designation.
