Enduro bearings s6805 llb - 440c stainless (radial) - 25x37x7

STAINLESS: Enduro Bearings manufactures select ranges of bearings constructed with stainless 440C steel balls. This material offers maximum resistance to corrosion in all circumstances. Depending on the application, Abec 3 or Abec 5 quality is used. Stainless steel balls have 20% less capacity than the 52100 steel balls used in most of our bearings, but they do have better protection against corrosion. Enduro Bearings uses a CRC marine grease in these bearings as extra protection against contamination. LLB: Our most popular seal, consisting of a rubber finish with a metal core. Unlike the standard 2RS, we go a little further by machining a notch in the inner ring, where the seal can rotate with excellent efficiency and resistance compared to a lesser bearing. Rather than a single «lip» of a thick seal that rubs against an uneven surface, the LLB type uses 2 lips of seals, fine like a razor blade that slides in a notch with a light contact. The outer «lip» keeps out water and impurities, while the inner seal retains grease for smooth rotation and long intervals between services.

As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro stainless bearings all carry a full two year anti-corrosion warranty. The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid the plastic insert MR 2437 is the correct bearing for the job The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
