National Precision Bearing, Inc. Heavy Duty Sealed & Unsealed Spherical Plain Metric Bearing

For application requiring extra load carrying capacity, NPB offers heavy duty spherical plain bearings. With the same bore diameter options as our standard series, the heavy duty series has larger inner and outer ring diameters, as well as wider outer ring widths (Figure 4). This provides increased surface contact to support heavier loads. In general, our heavy duty spherical plain bearings have 25% more capacity than that of standard duty bearings.
