National Precision Bearing, Inc. Self Lubricating Sealed Spherical Plain Metric Bearing

National Precision Bearing offers sealed spherical plain bearings to minimize the ingress of contaminants on to the bearing rotating surface and to help keep lubricant within the bearing (as shown in Figure 3). Seals are effective for operation within a temperature range of -10o F to +250o F. Special seal materials are also available for operation under extreme temperature beyond this range.
