Enduro Radial Bearing 61902 LLU / LLB A5 ABEC-5 (CN) HUB – 15 x 28 x 7mm

The Enduro Radial Bearing 61902 LLU / LLB A5 ABEC-5 (CN) HUB – 15 x 28 x 7mm is engineered for bicycle applications, featuring 52100 high-Carbon Chromium alloy races and grade 10 balls for maximum durability. Its deeper grooves accommodate larger balls, increasing bearing contact area and extending life. The LLU/LLB seal combination provides superior protection: a gray LLU seal faces outward to resist water and dirt, while a black LLB seal faces inward to retain the 90% fill Mobil XHP 222 high-pressure grease. Primarily used as a hub bearing, it can also function as a pivot bearing, offering robust performance against the elements.
