6x12x4 Rubber Sealed Bearing MR126-2RS 10-Pack (TFE272)

Six-by-twelve-by-four millimeter rubber-sealed bearings, sold in a 10-pack, are compact precision bearings designed to replace worn units in small hobby gear. They’re ideal for RC cars and other miniature models where smooth, low-friction rotation matters.

Rubber seals help keep out dust and moisture, preserving lubrication and extending bearing life in dusty or damp conditions. These bearings fit components sized for 6x12x4 mm bore dimensions, so be sure to verify the correct size in the model’s manual before installing.
