How do I tell if a bearing needs replacing?

Look for play, rough rotation, clicking noises or visible wear on the races. Any of these signs indicate a bearing replacement is due.

Is it okay to run sealed bearings without cleaning?

Sealed bearings require less cleaning than open types, but you should still inspect and clean the exterior and refresh lubrication if performance drops.

Can I use these bearings in vintage RC restorations?

Yes, where the dimensions match, these modern sealed bearings can be a straightforward swap to improve longevity and smoothness in older models.

Do sealed bearings affect top speed?

Properly sized, low-friction sealed bearings can reduce drivetrain losses and help maintain top speed by improving rolling efficiency.
