Enduro Lager MR 27537 LLB 27.5x37x7 ABEC 3

ABEC 3: A standard value that is used for measuring the wtolerance 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, the minimum standard ABEC 3. ABEC 3: Steel bullets degree 10. Baan in an alloy of chrome 52100 and high -quality carbon. ABEC 3 Standard. Depending on their application, these bearings use LLU or LLB closures; Even when they are marked with 2RS. LLB: our most popular seal, consisting of a rubber finish with a metal core. In contrast to the standard 2RS, we go a little further through the mechanical placement of a notch in the inner ring, where the seal can run with an excellent efficiency and a resistance compared to a lesser bearing. Rather than a single «lip» of a thick seal that sands against an uneven surface, the type of LLB uses 2 lips of seals, fine such as a razor blade that slides into a notch with a light contact. The outer «lip» keeps water and impurities out, while the inner seal retains the fat for smooth rotation and long intervals between the maintenance.
