3RACING 3RB-MR84-2RS/2 High Duty Double Rubber Sealed Bearings 4x8x3mm Pair  [3RB-MR84-2RS/2]

Precision sealed bearings for tuning and performance

In race setups where reliability and repeatable rotation matter, the 3RACING Double Rubber Seals Bearing in 4 x 8 x 3 mm offers stable performance under load. Supplied as a matched pair, these bearings support consistent lap times by reducing variance from contamination and seal wear.

Sealing for race environments

The double rubber seals minimise ingress of grit and fluids that can affect bearing preload and runout. That containment maintains predictable bearing behavior between pit checks, making these suitable for club level racing and practice sessions.

Installation and service notes for tuners

Press bearings square to the housing using a tool that contacts the outer race to avoid inducing play. Inspect seals for nicks after each session and reapply a light, race-grade lubricant as part of routine maintenance to keep friction consistent without compromising the seal.
