Performance Bearings for Competitive RC

The BB-730-4A from Yokomo is a four-piece pack of 3x7x2.5mm ball bearings intended as direct replacements or spare parts for race-focused models. They are compact parts engineered to support reliable rotation where space is limited.

Supported Chassis and Uses

These bearings are compatible with a broad selection of Yokomo chassis, such as the MRTC-BD10 and MSR-BD11 lines. They work well for owners seeking consistent bearing performance across practice and race conditions.

Why Fit Genuine Bearings

Quality bearings help reduce drag in wheel hubs and drivetrains, cutting down on wear and helping to preserve precise steering response and power delivery over many runs.
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.

Can I fit these to vintage Yokomo models?

Many older Yokomo models use the same 3x7x2.5mm seat sizes, but confirm the bearing thickness and outer diameter match your original parts before fitting.

Should I replace all bearings at once?

Replacing bearings in matched positions is advisable to maintain even wear and consistent handling, though swapping individual failed bearings is acceptable in a pinch.

What maintenance keeps them working longer?

Periodic cleaning to remove grit and applying a light bearing oil will preserve smooth rotation and extend service life.

Are these sealed or open bearings?

These are typical open-style miniature ball bearings; check the product notes for lubrication and sealing options if you need additional protection.
