50mm Axle Bearing with 90mm OD. This axle bearing is for certain karts where the outer diameter is 90mm! 

Note: Most karts do not utilize a 90mm OD bearing! Be sure to check yours to ensure this is the correct size before ordering! 

  • Depending on your bearing cassette application, the outer diameter of the overall bearing assembly may vary. Because of this, we urge you to consider the dimensions outlined here.
    • Also, select from different bearing grades: Standard, or RHP (performance)
      • A standard bearing will wear slightly faster, and may be lower quality than the RHP. The standard bearing is great for cost-effective karting applications, like rental karts or track day karts that will be abused heavily.
      • The RHP bearing, while pricier, will have a longer service life, and less rolling resistance. This bearing is intended for performance applications.

Each axle comes as pictured, with set screws, packed and ready to install.
