Miniatura Métrica 689ZZ

Deep Groove Ball Bearing is a 9mm ball bearing that is found in many applications. 689ZZ Metric Miniature Ball Bearing has two non-contact metal shields one on each side of the ball bearing. If your application requires a 689ZZ ball bearing with only one shield you can get this ball bearing and take one of the shields off. This 17mm ball bearing 689ZZ is high quality and can take electric motor demands if needed.

Rolling ball bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling ball bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
