Enduro Bearings S71806 LLB - 440C Stainless (Angular Contact) - 30x42x7

STAINLESS: Enduro Bearings produces certain ranges of bearings manufactured with 440C stainless steel balls. This material offers maximum resistance to corrosion in all conditions. 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 offer 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 recess 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 rubbing against an uneven surface, the LLB type uses 2 sealing lips, thin as a razor blade that slides into a recess with light contact. The outer "lip" keeps water and impurities out, while the inner seal retains the grease for smooth rotation and long maintenance intervals.

Made from high-quality 440C stainless steel, this angular contact bearing features ABEC-5 precision and a dimension of 10mm x 42mm x 7mm, suitable for various bottom bracket applications. The waterproof, high-pressure grease ensures maximum corrosion resistance, ideal for wet and demanding conditions. With correct installation and adjustment, Enduro angular contact bearings ensure an even distribution of force across all balls, which reduces wear and extends service life—crucial in applications with constant side loads such as bottom brackets. Made from premium 440C stainless steel, known for its high strength, hardness, and wear resistance, these bearings offer superior durability and corrosion resistance, even in harsh environments. They are suitable as a direct replacement for BB30, PF30, BB386, and other bottom brackets with a 30mm OD spindle, and come with a two-year anti-corrosion guarantee. With deep grooves, double lip seals, and available in ceramic-hybrid and XD-15 variants, these bearings are designed for optimal protection and performance. Weighing only 24.8g, they combine lightweight design with high durability for demanding cycling applications.
