Performance oriented sealed bearing solution

Specifically for tuners and racers, the 3Racing Double Rubber Seals Bearing 5 x 8 x 2.5 mm delivers consistent rotational behavior with reduced contamination risk. The sealed construction preserves lubricant and shields the rolling elements from debris commonly found on race surfaces.

Seal design and service life

The dual rubber seal arrangement limits ingress of particulate matter and moisture while retaining grease on the raceways, which helps maintain predictable bearing drag and extends service intervals in setup and testing cycles.

Applications in high demand setups

These 5 x 8 x 2.5 mm bearings suit wheel hubs, pinion supports, and compact gearbox shafts in 1/10 scale and similar class vehicles. Their standard geometry makes them a practical option for teams seeking reliable, low maintenance bearing options during event weekends.

What tolerances should I expect for these bearings?

Expect standard hobby grade tolerances suitable for typical RC drivetrain use; for precision racing builds consider matching to high tolerance race bearings and verifying fit on shafts and housings.

How do seals affect bearing drag in tuning?

Rubber seals add minimal drag while offering superior contamination control. For critical friction tuning, compare sealed and open bearings on a controlled test rig before final selection.

Are these bearings suitable for high RPM pinions?

They are suitable for many high RPM applications within hobby constraints, but verify thermal conditions and lubrication retention during extended high speed runs to ensure reliability.
