The 1150 (5x11mm) ball bearing is the most commonly used size that can be used in the vast majority of Tamiya R/C kits. This specific set uses rubber seals to help keep debris from the ball bearings found behind the seal. Use this set to improve efficiency and speed of your favorite Tamiya R/C kit.
