Why Fit 3RACING 3RB-MR85-2RS/2 in Your Model

The 5x8x2.5mm 3RACING double rubber sealed bearing comes as a pair and is aimed at reducing contamination in wheel hubs, servo linkages and small gearboxes. The sealed design helps keep abrasive particles out so components run cleaner between services.

Seal Protection Reduces Wear

Double rubber seals create a barrier against dust and water that would otherwise shorten bearing life. For operators who run on mixed surfaces, sealed bearings are an easy upgrade to improve reliability under varied conditions.

Universal Use Across Small RC Parts

These bearings are suitable for many compact locations in 1/10 and similar scale models where a 5x8x2.5mm bearing is needed. Installing the 3RACING sealed pair is a small step that can smooth steering and drivetrain action.

Will these bearings cope with beach sand conditions?

The double seals offer better protection than open bearings, but fine sand can still penetrate over time; rinse and inspect bearings after seaside runs.

Do these come pre-greased?

Yes, sealed bearings are typically pre-lubricated during manufacture, giving immediate smooth operation from new.

Can I use these in high RPM applications like brushless motors?

They work well in low to moderate RPM spots; for motor bearings you should check bearing specifications and motor maker recommendations for high RPM service.

How do I know when a sealed bearing needs replacing?

Look for increased drag, noise or play in the shaft. If the bearing feels rough or binding replace it to avoid damaging linked parts.
