What is the Enduro 6800 LLB Radial Bearing used for?

The Enduro 6800 LLB Radial Bearing - C3 Clearance | 10x19x5mm is a standard-design cartridge bearing used most often as a hub bearing in quick-release hub designs and pedal internals, with occasional duty as a frame pivot bearing. The C3 internal clearance is what makes this version the right call for hub work, where slight preload and thermal expansion under bearing seat tolerances need a bit of room to settle in. Deep-groove races, Grade 10 chrome steel balls, and a 90 percent fill of Mobilux NGLI 2 high-pressure waterproof synthetic grease give it long service life under daily abuse.

Enduro engineers every bearing in this line with the deepest race grooves possible to accommodate the largest balls the dimensions allow, which translates to more contact area and longer life under load. The LLB dual-lip labyrinth seals ride in a micro-groove to create a full labyrinth path, holding grease in and contaminants out without adding meaningful drag. For suspension pivot duty, Enduro recommends the MAX-type version of this size instead since MAX bearings are purpose-built for the twisting multi-directional loads at a pivot. This bearing is the right replacement for mechanics rebuilding QR hubs, pedal bearings, or any 10x19x5mm hub application.
