Perfect for Drones

Replaced stock bearings on my racing drone. Flight time improved due to less friction. Highly recommend for high RPM motors.

Very Smooth

Used these for a miniature projector fan. They are incredibly quiet and spin freely right out of the pack.

Good Value

Overall great bearings. One out of ten felt slightly gritty but the rest were perfect. Good price for the quantity.

Exact Fit
