Product Description

ION - XNOVA 4020 / 4535 Performance ABEC-5 Yellow Seal Motor Bearing Set (3pcs)


Replacement bearings to fit:

  • USE FOR: X-NOVA motors 4020 up to Larger 4535 Motors
  • Includes: (3) True Nitrile yellow seal (to keep dirt/dust out), deep groove high RPM precision ball bearings


  • Replace your stock XNOVA motor bearings with these precision ABEC-5 "Yellow True Nitrile rubber seal" bearings with high tolerance precision, and smoothness.
  • Bearings are sealed and pre-greased for quick drop in replacement.
  • The Yellow Nitrile Rubber seals keep gear dust, metal shavings and other contaminants out, which is what can damage normal bearings that are not sealed.
  • The quality nitrile rubber seals keep the bearing grease uncontaminated and contained which prolongs the life of the bearings greatly.
  • Sealed bearings are known to have a longer lifespan than regular bearings in RC helicopter applications, especially when dust and debris are present.


If it doesn't specify which ABEC rating, it's likely that's it's ABEC-1, or lower!  Some helicopter kits come standard with ABEC-1 bearings. ABEC-5 bearings are much tighter in tolerance than ABEC-1 bearings, thus providing much higher accuracy, longer life, and more smoothness.
