This 624ZZ 4x13x5-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.

Metal shields on both sides of the bearing keep the lubricant in and contaminants out. This bearing is intended for use in applications such as radio control (RC) vehicles or in personal projects. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads.
