Fine-Tune Steering with Yokomo BB-840PA Bearings

If you want crisper steering response in your RC model, the Yokomo BB-840PA ball bearings are a compact upgrade. With a 4mm inner diameter and an 8mm outer diameter, these precision bearings work well in steering wipers and other tight-fit components.

Benefits for Steering Control

Yokomo is known for reliable RC parts, and the BB-840PA delivers smooth rotation and reduced friction to help steering feel more direct. Whether trimming a race car or keeping a daily-runner maintained, these bearings help maintain predictable steering inputs.

Fitment and Use

The Yokomo BB-840PA bearings fit in a range of 1/10 scale models and other builds that accept 4x8x3mm bearings, making upgrades or replacements straightforward for most hobbyists.

Can I install these bearings in places besides the steering assembly?

Yes. Any mounting point that requires a 4x8x3mm bearing can use the Yokomo BB-840PA, so they are useful for linkages, small idlers, or other low-load rotating parts.

How should I care for these bearings to keep them working well?

Clean them from grit and apply a light bearing oil or thin grease as needed. Regular checks and simple lubrication will extend service life and keep steering smooth.
