What does ABEC 11 bearings mean?
ABEC is an acronym for Annular Bearing Engineering Committee of the AFBMA (Anti-Friction Bearing Manufacturers Association Inc). The ABEC scale of bearings is a set of standards for the manufacturing tolerances of bearings. All quality manufacturers around the world manufacture to at least ABEC 1 standard.
Are ABEC 1 bearings fast?
Higher precision bearings are designed to allow high precision machinery to operate smoother and sometimes at higher speeds than a standard bearing would allow. Keeping this in mind, a standard ABEC 1, 608ZZ is rated with a limiting speed of 32,000 RPM with grease lubrication and 38,000 RPM with oil lubrication.
The ABEC rating system goes
ABEC 1 Approximately equal to ISO P0
ABEC 3 Approximately equal to ISO P6
ABEC 5 Approximately equal to ISO P5
ABEC 7 Approximately equal to ISO P4
ABEC 9 Approximately equal to ISO P2
