Racing grade sealing and consistency for 3RACING 3RB-R188-2RS/2

Engineered for performance applications, the 3RACING Double Rubber Sealed Bearings (1/4 x 1/2 x 3/16) provide stable rotation and protection against particulate ingress, aiding repeatable lap times and reduced pit maintenance.

Seal design and performance benefits

The dual rubber lip configuration limits contamination of the lubricant film, keeping internal components cleaner under race conditions and preserving rolling resistance characteristics across event runs.

Suitable racing fitments

These bearings are commonly used in wheel hubs, diff carriers and idler assemblies where the 1/4 inch inner dimension is specified. They offer a balance of protection and low drag that fits competitive tuning priorities.

Installation and inspection protocol

Press bearings using a correct outer race driver to avoid loading the inner race. Verify housings for concentricity and recheck seal integrity after initial running to ensure no installation damage occurred.

What running conditions are these bearings optimised for?

They are optimised for dusty and mixed-surface race environments where sealing extends service intervals without materially increasing rolling drag.

How should these bearings be installed to preserve seal integrity?

Use a precision press or driver on the outer race, maintain alignment, and avoid hammering the inner race to prevent seal deformation or failure.

Are these bearings suitable for tuning upgrades in a racing build?

Yes, they are a common upgrade for reducing maintenance between events while retaining reliable rolling performance; pair with properly sized shafts and housings for best results.
