Information

ABEC 3 radial bearing with 8 mm inner diameter, 22 mm outer diameter, 7 mm width and double lip seal with light contact, running on 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 treads. 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 shells are manufactured in a vacuum process and hardened to Rockwell hardness R-62, followed by polishing to ABEC-3 Precision and noiseless operation.The riveted steel cage increases the toughness.
