Mountain bikers refreshing a linkage or pivot that uses a 6804 (20 x 32 x 7 mm) bearing.
The Enduro 6804 LLU MAX is a 20 x 32 x 7 mm cartridge bearing made for the slow, heavily loaded movement of suspension pivots. Enduro pioneered MAX-type bearings for mountain bikes, and this size has been used as a pivot bearing by brands including Orbea and Santa Cruz.
MAX bearings pack in as many balls as possible through a slot ground into the races, giving 35 to 40% more load capacity than a standard radial bearing. Deep-groove races, Grade 10 balls and LLU full-contact double-lip seals on both sides keep the grease in and the grit out, with a 90% fill of Almagard high pressure grease.
Because of the filling slot, MAX bearings trade a little smoothness for strength, which is exactly what a pivot needs. For hubs and other fast-spinning jobs, a standard radial 6804 is the better pick.

MAX design
The maximum number of balls is loaded through a ground slot in the races, giving 35 to 40% more load capacity than a standard radial bearing, which suits slow, high-load suspension pivots.
LLU seals
Full-contact, double-lip labyrinth seals give the most protection from water and dirt.

Maybe not for
Size 6804: 20 mm bore, 32 mm outside diameter, 7 mm wide. Sold as a single bearing, so count how many your linkage needs.
Replace pivots as a set
Pivot bearings usually wear together, so replace every bearing in the linkage at once. Press them in with a proper bearing press that pushes on the outer race, never by hammering on the seals.
Bearings made for bikes.
Enduro Bearings makes cartridge bearings designed specifically for bicycles, from hubs and bottom brackets to headsets and suspension pivots.
The range covers high-carbon chromium steel, 440C stainless steel and ceramic-hybrid bearings, all built with deep-groove races and dual-lip labyrinth seals to keep grease in and grime out.
