• Durable Alloy Races: 52100 high-carbon chromium alloy races provide strength and long service life
• Grade 10 Balls: High-quality ball bearings help improve rolling efficiency and consistency
• LLU/LLB Seal System: Protective outer seal helps resist dirt and water, while the inner seal reduces drag
• High-Pressure Grease Fill: Mobil XHP 222 grease helps protect the bearing and maintain smooth operation

Product Overview
The Enduro Bearings 61902 LLU/LLB CN ABEC 5 radial bearing is engineered specifically for bicycle use, offering a strong balance of smooth rolling performance, durability and weather protection. Enduro’s deep-groove race design allows the use of larger balls, increasing contact area and helping to extend bearing life. The LLU/LLB seal combination places a more protective LLU seal toward the outside to guard against water and dirt, while the lighter-contact LLB seal faces inward to reduce drag and retain grease. This bearing size is generally used as a hub bearing and may also be used in some pivot applications, although MAX-type bearings are better suited for suspension pivots.
