NOTE: If a Manufacturer does not specify ABEC rating, it's likely ABEC-1, or lower(not rated). Many helicopter kits come standard with ABEC-1 bearings. ABEC-5 bearings are made much tighter in tolerance and precision when compared with ABEC-1 bearings, thus providing much higher accuracy, longer life, less vibration, higher efficiency, and more smoothness.

Below is a example to show precision differences between common ABEC 1, 3, and 5 rated bearings.
