Information

ABEC 3 radial bearing with 15 mm inner diameter, 28 mm outer diameter, 7 mm width and double lip seal with light contact, running in a groove in the sense of a labyrinth seal. ABEC 3 bearings use grade 10 chrome steel balls and 52100 high carbon chrome alloy raceways. The precision balls are round with a deviation of 10/1000000", which is twice as round as the industry standard. The alloy of the bearing cups are manufactured in a vacuum process and hardened to Rockwell hardness R-62. Then they are polished to a mirror finish for ABEC-3 Precision and silent operation The riveted steel cage increases toughness.
