Spherical Plain Bearings – or SPBs, spherical plane bearings or ball bushings – are used when alignment between a shaft and housing have to accommodate movement, or where rotating tilting movements are required. So, they are found in applications that require rotation or oscillation.
SPBs are available in options that require lubrication or maintenance-free. There are also many styles of these ball bushings. The chart below breaks down their features and characteristics.
