💡 Why use ceramic hybrid ABEC-5 bearings in small setups?
These tiny bearings need high performance with low friction.
-
Ceramic balls cut friction and heat for better RPM
-
ABEC-5 tolerances mean tighter precision and longer wear
-
Ideal for micro drones, reels, tools, and precision drives
-
Low maintenance and corrosion resistance
Small but mighty, grab this 10-pack and let your high-performance projects spin right!
Have not installed them yet, but based on past experience, they will be great.
I have performed detailed coefficient of friction tests on various types of clock bearings including plain pivots jewels and ball bearings. Ball bearings have fifty time less friction than plain pivots. My testing is quite scientific and uses a stop - start technique as exhibited by clock trains. The use of hybrid ceramics ensure no "adhesive wear" due to micro welding of like metals in contact. Use without lubrication for longest life and lowest friction.
Recommended by specialists to avoid micro welding
Bearing are being used to reduce friction in mechanical clocks. This has meant that less weight is required and therefore less wear on the clock
