This double-row radial bearing features 52100 high-carbon chromium steel races paired with Grade 10 balls. The double-row design minimizes flex in the BB spindle while doubling the bearing contact area, enhancing stability and longevity. Deep-groove raceways, LLB seals, and 90% fill of high-pressure waterproof grease ensure smooth performance and protection against daily wear and the elements.
This bearing is used exclusively in Stronglite ISIS bottom brackets.
Enduro bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. All bearings are engineered with the deepest groove races possible to accommodate the largest balls and feature dual-lip seals riding in a micro-groove to form a full labyrinth, providing superior protection against dirt, water, and other contaminants.
