A standard value used to measure the surface tolerance of roller bearings. There are five classes: 1, 3, 5, 7, and 9. The higher the ABEC class, the greater the precision, efficiency, and speed capacity, but the highest ABEC classes are not necessarily the fastest-rotating components. All quality manufacturers worldwide use at least ABEC 1 as the standard. For 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 either LLU or LLB seals, even when marked 2RS.
