Enduro Bearings 686 LLU - ABEC 3 Black Oxide - Ball Bearing - 6x13x5mm

Blacked ABEC 3 MAX radial bearing with 6 mm inner diameter, 13 mm outer diameter, 5 mm thickness and double-lip type sealing with strong contact, making a labyrinth seal. Black Oxide bearings with their additional Fe3O4 Iron Oxide (Magnetite) treatment got the corrosion resistance close to stainless steel, but with much better load capacity. ABEC 3 bearings use grade 10 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races. The high precision balls are within 10/1.000.000″ round, twice as round as the industry standard, at it's highest level. The alloy races are made from a vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement. The riveted Steel Retainer stands for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance.
