CØ 6903-LLB Zero Ceramic Enduro Bike Bearing 17.00x30.00x7.00

  • Silicon Nitride (Si3n4) Grade 3 balls
  • LLB type seal
  • Magnetite Rust Proof Finish

Typical applications: Hub Bearings

ZERØ ceramic bearings have ceramic balls and steel races.  The balls are Grade 3, Silicon Nitride (Si3n4). The races are treated with a black oxide coating, which helps prevent rusting in the bearing. The races are then reground to a mirror finish after this treatment. Finally, they are cryogenically treated for strength before assembly.

Si3N4 balls with 52100 High carbon Chromium Alloy Races with Cryogenic Treatment:
 Cryogenic treatment takes the races down to minus three hundred degree Fahrenheit to normalize the crystalline structure of the material so the races will resist the hardness of the ceramic balls and get the maximum wear potential.

Fastest, smoothest bearings I’ve ever used.
11 October 2024  | 

Had to replace the original wheel bearings in my Bontrager wheels. Although these are expensive they are well worth the money. The wheels now roll for ages with much less lateral movement in the frame. Out on trail the bike is so much faster, precise and carry’s way more speed than it did before with the stock bearings. A true value for money upgrade.
