Ball Bearing 3x7x3, model accessory, 10-pack

Ball bearings are a core detail in model mechanics, and this 10-pack brings the exact 3 x 7 x 3 mm size into the workshop for precise replacement and setup work. The compact format suits small rotating assemblies where clean running and an accurate fit matter, whether the bearing is used in a fresh build or during routine maintenance. Each bearing is a metal component designed for model applications that rely on controlled rotation at compact mounting points. The pack of 10 supports repeated service jobs, keeps matching spares together and helps maintain consistency across assemblies that use the same dimension. The 3 mm inner diameter, 7 mm outer diameter and 3 mm width make the size easy to match against existing parts before installation. This makes the set useful for hobby benches where exact dimensions guide part choice more than broad category labels. In practice, the bearings fit naturally into repair sessions, rebuilds and parts organisation for model projects from 14 years. Stored as a dedicated size set, they are ready when a worn bearing needs replacing or when a mechanical assembly calls for the same format at several rotating points.
