Solid bearings

Good value for a pack of 10. One felt slightly stiffer than the others but loosened up after use.

Perfect for my drone build

Smooth rotation and very low friction. Noticed less heat buildup compared to steel bearings.

5 FAQ

Q: What is the ceramic material type?

A: We use Silicon Nitride (Si3N4) balls for high durability and heat resistance.

Q: Is the outer ring ceramic as well?

A: No, these are hybrid bearings. Only the balls are ceramic; the rings are high-carbon chrome steel.

Q: Do I need to lubricate them before use?

A: No, they come pre-lubricated with high-speed grease ready for installation.

Q: Can these handle axial loads?

A: They are deep groove ball bearings designed primarily for radial loads with limited axial capacity.

Q: Are these suitable for high-speed spindles?

A: Yes, they are designed for high RPM applications depending on the specific bore size.
