Inch series radial spherical plain bearings, requiring maintenance, steel/steel, ANSI/ABMA Std. 22.2-1988

Chrome steel inner ring and outer ring, precision ground, hardened, phosphated.
This spherical plain bearing has a single fractured outer ring.
The inner ring and outer ring are coated with molybdenum disulfide for reduced sliding friction.
The bearing can be relubricated via lubrication holes and an annular groove in both rings.
This spherical plain bearing must be properly lubricated with grease.
