Sealed bearing solution for reliable hobby running

The 3Racing Double Rubber Seals Bearing 8x16x5mm is a practical sealed bearing choice for model builders wanting dependable performance with less cleaning. The double rubber seals keep contaminants out while retaining lubricant for steady operation.

Engineered for common RC applications

These bearings are suitable for many wheel and drivetrain positions, offering a balance of protection and reliable rotation for club-day cars and everyday crawlers alike. They are built to withstand routine hobby use without fuss.

Best practices for installation and care

Ensure bearing housings are free from debris before pressing in the bearings, and use a correct driver to avoid stressing the seals. Regular inspections and swapping units at the first sign of wear will protect adjacent components.

Can these replace open bearings in my kit without modding?

If your kit calls for 8x16x5mm bearings, these sealed units should fit as direct replacements, but confirm bore tolerances and shaft fits first.

What are the signs a sealed bearing needs replacing?

Look for increased noise, rough rotation, or side play. Any of these signs means it is time to replace the bearing to avoid damage to the hub or axle.

Are these bearings suitable for light track use?

Yes, for club-level track days they offer good protection with minimal extra maintenance, though racers may prefer serviceable options for fine tuning.
