Product description：
This 688ZZ 8x16x5-millimeter shielded miniature ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. Its chrome steel construction makes it durable and resistant to deformity under heavy loads. The metal shields on both sides of the bearing keep lubricant in and contaminants out, and it comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove shielded miniature ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.
