High Precision 4x8x3 Bearings

Arrowmax AM-200123 4x8x3 ball bearings are intended for small RC assemblies where tight tolerances matter. These metal bearings offer precise rolling surfaces to keep components turning freely.

Key Advantages

Reducing friction is the main benefit of quality bearings. The Arrowmax AM-200123 units help lower operating temperatures and reduce wear on axles and gearbox parts when properly installed.

Best Use Cases

These bearings work well in wheels, steering linkages, idler pulleys and compact gearboxes that accept 4x8x3 bearings. They are a practical upgrade for hobbyists refreshing running gear.

Do these require special tools to fit?

Basic press-fit tools or careful tapping with a soft drift are usually enough. Avoid hammering directly on the inner race to prevent damage.

Which lubricant is best?

A light bearing oil or thin synthetic grease designed for small bearings works well; thicker greases can slow rotation and attract dirt.

How do I spot a worn bearing?

Listen for roughness, feel for play or binding, and inspect for discoloration or pitting. Replace if rotation is not smooth.
