Description
Factory Team 5x12x4 mm ball bearings, four-pack, are small, high-precision bearings designed to replace worn or noisy bearings in RC models and other compact mechanical assemblies. The 5x12x4 mm size keeps rotations smooth and minimizes friction for steadier performance during runs and races.
These standard-size bearings are commonly used in 1/10-scale RC setups such as the RC10B5M and fit shafts and hubs with a 5 mm inner bore and 12 mm outer diameter. With a four-pack on hand, maintenance is quick and downtime is minimized, helping components turn smoothly between sessions.
