These radial cartridge bearings meet the ABEC-5 tolerance standard. They feature high-precision chromium steel balls that are smooth rolling and durable.

HIGHLIGHTS

• ABEC-5 radial bearing is designed specifically for bicycle applications
  
• 52100 High-Carbon Chromium alloy deep-groove design races help to promote a longer bearing life
  
• Precise long-lasting Grade 10 Balls are made from 52100 Chromium Steel
  
• 90% fill with Mobil XHP 222 high-pressure waterproof grease
  
• LLU seal facing outward, towards the elements, to reduce contamination from water or dirt
  
• Lighter-contact (less seal-drag) LLB seal facing inward keeps the grease where it belongs
  
• CN clearance specification is best for looser press-fit bearing bores
