• 40mm ID Rear Axle Bearings.
• These bearings are initially manufactured for Righetti Ridolfi karts and axles, but will work for many karting applications.
• Each bearing is complete, with (2) drilled and tapped set screw hole locations for maximum grip on axle.
• 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 bearing comes complete, with set screws for clamping to axle included.
