• Direct replacement / Upgrade for Stock SAB Goblin Bearing HC488-S

• Replace stock bearings with high quality Precision ABEC-5 Yellow nitrile rubber seal bearings with high tolerance, and ultra smoothness.
• These bearings are sealed, pre-greased and ready to go.
• The Yellow Nitrile Rubber seals help keep gear dust and metal shavings out, which is what can damage normal bearings that are not well sealed.
  
• The high quality Nitrile Rubber seals help keep the grease clean, contained, and uncontaminated.
• Sealed bearings usually have a longer lifespan than regular bearings in RC helicopter applications, especially when dust and debris are present.
• The special nitrile yellow seals can be removed and reinstalled quickly and easily, if desired by the user.
• Deep groove geometry helps support both radial and axial loads!

If a Retailer/Vendor does not specify an ABEC rating, it's likely ABEC-1, or lower(not even rated). ABEC-5 bearings are much tighter in tolerance, thus providing much higher accuracy, longer life, and ultra smoothness.
