Phil Wood Upgrade sealed cartridge bearing.

Zero Ceramic bearings are the ultimate race day weapon. Oversized Grade 3 balls roll on races which are ground to a mirror finish after receiving Magnetite and then Cryogenic treatments for hardness and longevity, and slippery Silicone seals to produce minimum resistance.

• All measurements are in millimeters
• ABEC 5 precision cartridge bearing
• CERBEC USA Grade 3 Si3n4 Silicon Nitride balls
• 52100 high carbon Chromium alloy races
• Races receive 3 cryogenic treatments and a rust proof Magnetite finish
• "VV" type 2-lip non-contact Silicone labyrinth seals
• Nylon/graphite retainer

MAX type bearings are designed specifically for suspension pivots. Using a special design where the maximum number of balls are inserted into the bearing, they have more load capacity than standard radial bearings The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with suspension pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.

• 90% filled with Mobilux NGLI 2 synthetic grease, dual-lip labyrinth seals, full complement of bearings, up to 45% increased load capacity

Enduro Angular Contact bearings engage all of the bearing’s balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. This is particularly important in applications like BBs, where there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure.
