Enduro Lager 71902 LLB 15x28x7 ABEC 5

ABEC 5: 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 is 5: Steel bullets degree 5: Bullets with a spherical formation with a precision of 5/1,000,000. This is a military level and therefore excellent to use with precision applications. ABEC 5 Standard: this bearing must pass all tests; These are noise at high speed, very narrow tolerances que accuracy regarding indoor and outside diameter, perfect spherical shape, accuracy of the track and the finish of both lane and bullet. These bearings are treated with a high -quality Teflon lubricant (Rheolube 374A). 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.
