Enduro bearings 689 llb - abec 3 (radial) - 9x17x5 Impac Sintered material for improved brakingA standard value that is used for measuring the 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 capacity, but the highest ABEC classes are not necessarily the fastest rotating parts. All quality producers around the world use at least the ABEC 1 as standard. At Enduro is the minimum ABEC 3 standard. ABEC 3: Steel bullets degree 10.
