Race-Ready Rubber-Sealed Bearing Solution

The 3RACING Double Rubber Seals Bearing in 8 x 14 x 4 mm size is targeted at tuners seeking reliable, sealed rolling elements that minimise ingress during track running. These bearings help maintain consistent rotational behavior under varied track conditions.

Contamination Control for Track Performance

Rubber seals provide a controlled barrier that reduces entry of dust and debris into the raceway, helping to preserve lubrication and minimise irregular drag spikes that affect lap-to-lap consistency.

Installation and Setup Notes

Install using the correct drift to avoid seal distortion and check for lateral play after fitting. For racing setups, verify axle endplay and bearing preload to optimise drivetrain response without introducing binding.

How do sealed bearings affect differential and drivetrain tuning?

Sealed bearings add minor friction compared with open bearings, which can slightly alter pinion load and diff behaviour. Account for this when measuring drivetrain resistance during setup.

What installation practices preserve seal integrity?

Use a precision driver that contacts the outer race only, avoid hammering the seal face, and check runout after pressing to ensure seals remain undamaged.

Should I change grease type for track use?

Standard bearing greases are suitable; for racing, select a low-viscosity bearing grease to balance protection with minimal drag. Ensure compatibility with seal materials.
