Annular bearings are one of W.M. Berg’s quality engineered mechanical precision components. Annular bearings are spherical bearings with a split outer race. Composite annular bearings work well for oscillating motions, pivoting and slow speed full rotations. Annular bearings provide a low friction operation, with friction decreasing as the load increases. W.M. Berg annular bearings are made of high quality duralon with a Teflon liner. Annular bearings outside diameters range from 0.8750 to 2.0000.
