3RACING 3RB-R188-2RS/2 Sealed Rubber Bearings 1/4 x 1/2 x 3/16 Pack of 2  [3RB-R188-2RS/2]

Reliable protection from dirt with 3RACING 3RB-R188-2RS/2 sealed bearings

When you need bearings that shrug off grit and splash, the 3RACING Double Rubber Sealed Bearings (1/4 x 1/2 x 3/16) help keep moving parts turning true with less fuss.

Why the double rubber seal matters

Dual rubber lips form a barrier against dust and light moisture, preserving the internal grease and reducing the chances of gritty wear. That makes these bearings a sensible option for mixed-surface running.

Common fitting points

These parts are compatible with many RC layouts using the same dimensions, so they are handy for wheel hubs, idlers, and other rotating assemblies on both tracks and rougher surfaces.

Quick installation pointers

Use a straight press fit and avoid hammering on the inner race. Clean the seating bore and check for correct alignment to prevent premature seal damage.
