12x18x4 Rubber Sealed Bearing 6701-2RS (Pack of 10) (TFE270)

These are 12 by 18 by 4 millimeter rubber-sealed bearings, sold in a 10-pack, built to deliver smooth, reliable rotation for RC components. The rubber seals protect against dust and moisture while retaining lubrication for longer life and steady performance in everyday use.

A widely used standard size for hobby RC models, these bearings fit a range of axles, gearboxes, and other rotating parts. The rubber-sealed design helps maintain consistent operation in dusty environments, and the 10-pack makes it easy to replace worn bearings across multiple projects or builds.
