    This 16004-ZZ deep groove ball bearing with metric dimensions has double non-contact seals and a single-row deep-groove geometry for high speeds and supporting both radial and axial loads. The pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. The bearing has contact seals that fasten to the outer rings on both sides of the bearing and make light contact with the inner ring to keep lubricant in and contaminants out. This UBC 16004.2Z deep groove ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy and stiffness at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.

    Rolling 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 bearings are open, shielded, or sealed. Sealed and Shielded bearings are lubricated with oil or grease in the bearing factory, while open 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, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
