Enduro Bearings SMR 2437 LLB - ABEC 5 - Bottom Bracket Stainless Steel Ball Bearing - 24x37x7mm

SMR 2437 LLB - Stainless-Steel, Bottom Bracket bearing - 24mm x 37mm x 7mm

These Bottom Bracket bearings feature 440C Stainless Steel alloy races and balls with 90% fill, high-pressure, water-proof grease for maximum corrosion resistance

Not all stainless steel is created equal.

Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. 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 you 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 with 24mm BB spindles.

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 deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro groove creating a full labyrinth to provide ultimate protection against the elements.
