ENDURO BEARINGS Smra 2437 llb - 440c stainless (angular contact) - 24x37x7

Upgrade your bicycle with the high-performance SMRA 2437 LLB angular-contact bottom bracket bearing, designed for durability and optimal performance. Measuring 24mm x 37mm x 7mm, this bearing features 440C stainless steel alloy races and balls with a 90% fill of high-pressure, waterproof grease for maximum corrosion resistance. When properly installed (with the black seal in place for BBs) and correctly adjusted, Enduro Angular Contact bearings engage all the balls, distributing force evenly across a larger surface area, reducing wear and extending bearing life. This is especially crucial in applications like bottom brackets, where lateral loads are constantly changing, often causing premature failure. Not all stainless steel is equal—Enduro uses only 440C stainless steel for superior corrosion resistance and long-lasting performance in challenging environments. Although stainless steel has approximately 20% less load capacity and is slightly softer than standard 52100 chromium steel, it excels in wet conditions, frequent washing, or environments where sweat is an issue. Enduro stainless bearings come with a two-year anti-corrosion warranty. Ideal as a direct replacement for Shimano external cup bottom brackets with 24mm spindles, these bearings are available in various materials including high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. Engineered with deep groove races to accommodate larger balls and dual-lip labyrinth seals, they ensure long life and superior protection against the elements.
