Ball Bearing Set BT-01/MB-01, model spare part

This 18-piece ball bearing set is made for BT-01 and MB-01 models and brings a more precise running surface to the rotating assemblies inside the chassis. Metal bearings support axles and shafts where clean, consistent movement matters, making the set a practical choice for maintenance, repair or tuning work. The assortment shown includes multiple bearing sizes, allowing the set to cover different mounting points rather than a single location. Shielded bearings help keep the running surfaces enclosed, while the ring-shaped and smaller open-centre formats shown in the set extend its use across varied mechanical positions. In RC model drivetrains, bearings are used where wheels, gears or transmission parts rotate under load, so replacing worn bushings or tired bearings can restore smoother mechanical action. The dedicated BT-01 and MB-01 fit keeps the selection focused on compatible chassis instead of a generic mixed hardware pack. On the workbench, the set supports routine servicing before the next run as well as targeted replacement during a rebuild. It also suits enthusiasts refining a fresh chassis setup, where low-friction rotating points contribute to cleaner rolling and drivetrain response.
