Reliable 4x8x3mm Bearings by 3RACING 3RB-MR84-ZZ/10

When you need compact, dependable bearings for model servicing, the 3RACING Double Metal Shield Bearing 4x8x3mm set is a practical choice. These parts reduce friction and support dependable rotation in common RC assemblies.

Suitable Applications in Models

They are well suited to small axles, steering linkages and lightweight gearbox shafts, helping to maintain steering fidelity and smooth drive response on a variety of surfaces.

Shield Advantages for Longevity

Double metal shields give extra defence against coarse contaminants while keeping rotational drag low, which helps bearings last longer between servicing intervals.

Use Cases and Servicing

Keep this 10-piece set in your spares kit for routine maintenance or quick swaps during events; standard cleaning and light lubrication will keep them performing well.

Will these bearings fit vintage kits?

If the older kit uses 4x8x3mm bearings they are interchangeable, but check the part numbers or measure the original bearings before fitting.

What lubrication is best for these bearings?

A light synthetic bearing oil works well for speed and protection; reserve greases for low speed, high load points to prevent fling-off.

How do I replace a bearing that is stuck?

Use a drift sized to the inner race and apply steady pressure, or heat the housing slightly to ease removal; avoid pounding the bearing to prevent damage to surrounding parts.
