ENDURO S71806/29 LLB STAINLESS ANGULAR BB BEARING 30 X 42 X 7MM

S71806/29 LLB - Angular Contact, Stainless-Steel, Bottom Bracket bearing - 30 x 42 x 7mm -

This bottom bracket bearing, with angular-contact and ABEC-5 specifications, utilizes 440C stainless steel alloy races and balls that are filled up to 90% for maximum corrosion resistance. The high-pressure, water-proof grease ensures durability when properly installed (with the black seal in for BBs) and adjusted. The design of the Enduro Angular Contact (A/C) bearings engages all the bearing's balls, distributing force over a larger surface area, which greatly reduces wear and extends bearing life. This feature is essential for BBs, as they are subjected to constantly changing lateral loads that often cause premature bearing failure.

Not all stainless steel is created equal.

The ENDURO S71806/29 LLB STAINLESS ANGULAR BB BRNG 30 X 42 X 7MM uses only high-quality 440C stainless steel balls and races, providing exceptional corrosion resistance and longer lifespan even in challenging environments. This superior alloy offers remarkable durability and wear resistance due to its high carbon content, but it does come at a higher cost and requires specialized heat and cryogenic treatments for optimal performance. While stainless steel may have a 20% lower load capacity and be slightly softer than our standard 52100 chromium steel bearings, it serves as an excellent substitute for wet conditions, frequent bike washes, and areas prone to sweat.

This stainless steel bearing is compatible with SRAM DUB bottom brackets and has a 29mm outer diameter spindle. Its precise design ensures a perfect fit and smooth operation, making it an ideal choice for replacement use. Experience improved performance and longevity with this durable and reliable bearing.
