Compact Bearings for Smooth Running

The BB-730-4A from Yokomo is a set of four 3x7x2.5mm ball bearings tailored for modellers who want reliable, low-resistance rotation in their drivetrains. These compact bearings are convenient spares for routine maintenance and repairs.

Where They Fit

These bearings install cleanly into a range of Yokomo chassis types, covering platforms such as the MRTC-BD10 and MSR-BD11 series. They are chosen by people looking for consistent axle and gear support across several chassis layouts.

Long Term Value

With precise manufacturing to limit play and friction, these bearings help protect moving parts and support smoother steering input and throttle response over time.
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 standard size bearings for Yokomo spares?

They match common 3x7x2.5mm mounting points used in many Yokomo models, so they make handy spare parts for trackside fixes.

What lubricant should I use?

Use a light bearing oil or thin synthetic lubricant suitable for small model bearings to keep rolling friction low.

Can these bearings be pressed in by hand?

Small bearings often push in by hand if aligned correctly, but a bearing driver or socket is recommended to avoid damage.

Do they come pre-greased?

These typically arrive with a light factory lubricant; you can clean and re-lube to suit your track conditions.
