Enduro bearings 6702 2rs - abec 3 (radial) - 15x21x4

ABEC 3: A standard value used to measure the w tolerance of the surface of the roller bearings. There are five classes: 1, 3, 5, 7 and 9. The higher the ABEC class the greater the precision, efficiency and speed capability, but the highest ABEC classes are not necessarily the fastest rotating parts. All quality manufacturers around the world use at least ABEC 1 as standard. At Enduro the minimum standard is ABEC 3. ABEC 3: Steel balls Grade 10. Track in an alloy of chrome 52100 and high-quality carbon. ABEC 3 standard. Depending on their application, these bearings use LLU or LLB seals; even when marked with 2RS.
