Radial spherical plain bearing, requiring maintenance, sliding contact surface: steel/steel, extended inner ring, sealed, metric sizes
Radial spherical plain bearings are designed to accommodate radial and combined radial and axial loads, and also misalignment. The bearing can be relubricated via lubrication holes and an annular groove in both rings.
