Practical sealed bearings for everyday RC

The 3Racing Double Rubber Seals Bearing, sized 8x16x5mm, offers a straightforward sealed bearing option for hobbyists who want lower maintenance between sessions. The dual rubber shields keep grease in and contaminants out to help preserve smooth rotation.

Suitable for a wide range of RC models

Designed to be compatible with many common mounting points, these bearings are a good fit for street machines, park buggies, and casual off-road use. The focus is on durability and consistent service life under normal hobby conditions.

Fitment tips and inspection routine

Install bearings squarely using a driver that contacts the outer race or bearing ring, not the seals. Inspect for play or noise periodically and replace when performance drops to maintain drivetrain health.

Will these bearings tolerate sandy runs at the park?

The rubber seals offer good defence against sand, but heavy grit can still penetrate over time; regular checks and cleaning around the hubs will help.

Are these bearings user serviceable?

These are sealed units meant to be replaced when worn; for most users swapping them out is simpler and more reliable than attempting a seal service.

How do I check for bearing wear?

Rotate the fitted wheel or shaft by hand and listen for roughness or note play; any grinding or looseness indicates replacement is needed.
