✔️ 105mm bore x 160mm outer diameter sealed bearing pair
This item consists of two sealed ceramic ball bearings designed for high RPM applications. These units are commonly found in electric motors, bicycle hubs, or food processing machines where non conductive materials prevent corrosion.
✅ Zirconia ceramic balls resist rust and oxidation effectively
✅ Low density material cuts down rotation weight and inertia
✅ PTFE cage minimizes friction and temperature rise fast
✅ Rubber seals protect lubrication from dust entering gaps
