Motorcycle Bearing Finder

Search common metric bearing numbers and bearing sizes used on modern motocross motorcycles.

The finder can be used for wheel bearings, steering head bearings, swingarm bearings, suspension linkage bearings, shock bearings and many engine bearing applications.

Finding a Replacement Bearing

Many motorcycle bearings use standard metric bearing numbers. If the identification number can still be read on the original bearing, it is often the simplest way to locate a replacement.

If the number cannot be identified, measure the bearing's inside diameter, outside diameter and width accurately before searching.

Bearing Size Guide

Measurement	What It Means
Inside Diameter	The diameter of the hole through the centre of the bearing.
Outside Diameter	The total outside diameter of the bearing.
Width	The thickness of the bearing.
Seal Type	Check whether the original bearing is open, metal shielded or rubber sealed.

Buying and Installation Tips

Check the bearing number stamped on the original bearing before ordering.
Measure the inside diameter, outside diameter and width if the bearing number cannot be read.
Check the required bearing seal or shield configuration.
Inspect associated oil seals and dust seals when replacing wheel, swingarm or linkage bearings.
Use bearings suitable for the load, speed and application involved.
For engine bearings, confirm the exact bearing specification and required internal clearance before ordering.
Follow the motorcycle manufacturer's installation and torque procedures during assembly.

Important: A bearing with matching physical dimensions is not automatically suitable for every application. Bearing type, internal clearance, sealing, load rating and operating conditions may also be important.
