💡 Why use flanged ceramic ball bearings in compact precision systems?
They combine the mounting stability of a flange with the performance of ceramic balls.
- Run cooler and faster at high RPMs
- Offer strong corrosion resistance
- Ideal for RC, robotics, and high-speed instruments

A compact, high-performance bearing that keeps your setup smooth, quiet, and precise, small in size, big on performance.
