High-Quality 3x7x2.5mm Bearings

The Yokomo BB-730-4A set contains four precision 3x7x2.5mm ball bearings designed to keep rotating parts moving freely. They serve as direct replacements or spares for regular upkeep on race and hobby cars.

Compatibility Notes

These bearings fit many Yokomo chassis types, including the MRTC-BD10 and MSR-BD11 ranges. They are suitable for model owners who prioritise smooth wheel and gear rotation across varied track surfaces.

Advantages of Precision Bearings

By lowering internal friction, these bearings reduce wear on shafts and gearboxes and help maintain consistent lap times and handling feel during extended running sessions.
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.

Do these bearings suit high-speed shafts?

They are suitable for typical high-speed shafts used in on-road and touring models, provided the shaft diameter and housing match the bearing dimensions.

Is special tooling required to fit them?

A simple press or bearing driver makes installation easier and prevents damage; hand fitting can work for careful technicians.

How do I spot a worn bearing?

Listen for roughness, play in the shaft, or uneven roll; any of these signs indicate it is time to replace the bearing.
