BlackBearing Bearing 6902-2RS

BLACK BEARING 6902-2RS BEARING

Black Bearing bearings are specifically designed for cycling to withstand the most extreme conditions. Each component (balls, rings, cages, and grease) is manufactured and assembled with precision. They come in different versions to suit your needs.

Series B3

BLACK BEARING B3 bearings feature steel balls and are originally mounted by the vast majority of cycle manufacturers (frames, wheels, pedals...), urban sports (roller skates, scooters, skateboards, BMX...), motorcycles, ATVs, and modeling. They are manufactured in the largest factories and have been selected for their reliability, performance, and value for money.

• High-quality steel
• Quality grease
• Quality balls

Series B5

A Black Bearing B5 bearing is synonymous with reliability, smoothness, and durability. It is the best-selling bearing in the range.

• SAE52100 chrome steel balls
• SAE52100 chrome steel rings with ground raceways
• Chrome steel cage
• Reinforced "2RS" seals for better resistance to water and dust
• Superior quality grease

Series B5S

Stainless steel offers significant corrosion resistance. However, it is softer than steel, making this bearing less durable than a standard B5 steel bearing. The B5 Stainless Steel bearing is recommended for wet conditions.

• KS440 stainless steel rings with ground raceways
• AISI-304 stainless steel cage
• "2RS" seals resistant to water and dust
• Superior quality grease
