Stable Rotation for RC Models

The Arrowmax AM-200123 4x8x3 bearings provide reliable rolling contact for small shafts and hubs in RC gear. These metal bearings are sized for common hobby use and help maintain consistent rotational behaviour.

Why These Bearings Work

By replacing worn bushings or degraded bearings, the Arrowmax AM-200123 set reduces friction points and helps protect adjoining components. Precision manufacture means smoother motion and less vibration under load.

Where to Use Arrowmax Bearings

Use these bearings in wheel hubs, servo linkages, idler pulleys and other compact assemblies that require 4x8x3mm bearings. They are straightforward to fit and suitable for maintenance or light upgrades.

How do I check bearing fit?

Confirm bore and shaft sizes with calipers or the parts list. A 4x8x3mm bearing needs a 4mm shaft and an 8mm housing diameter for correct seating.

What maintenance keeps them lasting?

Periodic cleaning to remove dirt and a light application of bearing oil will extend service life; avoid over-greasing which can trap debris.

Are they sealed or open?

These are standard metal 4x8x3 bearings; check the product notes for seal style. Open bearings are common and allow cleaning and re-lubrication.

Can I mix brands in one model?

Mixing brands is fine as long as dimensions and quality match; using matched pairs from the same spec is best for predictable performance.
