Precision bearings for tighter RC setups

The Yokomo BB-1812-2 ball bearings are a compact upgrade for model parts where a 12x18x4mm size is required. They are commonly used in MO2.0 centre one-way limiters and similar small components to improve rotational smoothness and reduce mechanical resistance.

Practical fitment uses

These BB-1812-2 bearings will fit any assembly designed for 12x18x4mm bearings, including compatible positions on the MOR-020 chassis. They are ideal when you want to refine component behaviour without redesigning mounts.

Care and servicing tips

Before fitting, ensure bearing seats and shafts are clean and straight. A small amount of suitable oil will maintain performance; replace bearings showing roughness or excessive endplay.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Are these bearings sealed?

No, these are standard open-style bearings. They are easy to clean and relubricate but need protection from contaminants in dusty or wet conditions.

Can I use them on road and off-road models?

Yes. Provided the mounting accepts 12x18x4mm bearings, they are suitable for both surfaces; keep an eye on ingress from off-road runs.

How do I check for bearing wear?

Rotate by hand and feel for roughness, wobble, or noise. Any of these signs mean replacement is advisable to avoid further drivetrain damage.

Is installation reversible if fitted too tightly?

Removal is possible but may require a puller or press. Avoid hammering bearings out in a way that could deform the housing.

What is the best way to store spare bearings?

Keep spares in a dry, dust-free box with a light coating of oil to prevent rust; label by size so you can grab the correct 12x18x4mm unit when needed.
