SFK Deep-groove Ball Bearing, Plain Race Type, 12 mm ID - 61801-2Z This shielded ball bearing from SFK is able to handle very high rotational speeds and both radial and axial loads in either direction. It needs little maintenance, thanks to its two metal dust shields, which help retain the bearing's lubrication and do away with the need for re-greasing. The shields also prevent moisture and dirt from affecting the bearing's efficiency. Its low-friction steel composition increases the performance of high-speed machinery, such as motors that operate at fast rotations per minute. • Parallel bore type
