Inch series radial spherical plain bearings with an extended inner ring, requiring maintenance, steel/steel

This spherical plain bearing has an extended inner ring for cylinder connection.
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.
