GE20AW Spherical Plain Thrust Bearings, Bore 20 Mm, Maintenance-free, DIN ISO 12240-3, Open Design
The GE20AW Axial spherical plain bearings are commonly used in applications requiring heavy axial loads and allowing for a certain degree of oscillation, such as hydraulic cylinder piston rod lug connections, screw mechanisms in heavy-duty lifting equipment, valve actuators, bridge bearings, and gate hoists in hydraulic engineering projects.
The GE20AW bearing is a Axial spherical plain bearings with an inner diameter of 20 mm , an outer diameter of 55 mm, a width of 20 mm. Hardened rolling bearing steel rings, Hardened rolling bearing steel rolling mlement. Its dynamic axial rated load is approximately 225000 N, its static axial rated load is approximately 376000 N. It uses CN standard radial clearance, Open (No seal) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
GE20AW bearings ( 20 mm x 55 mm x 20 mm) have the advantages of Specifically designed to withstand high-purity axial (thrust) loads and possessing self-aligning capability to compensate for installation angular deviations, and are therefore widely used in the Commonly used in the lug connections of hydraulic cylinder piston rods, slewing supports in heavy-duty lifting equipment, and thrust joints in bridge bearings.

The GE20AW Axial spherical plain bearings consist of a shaft ring (inner ring) with a spherical convex surface, a seat ring (outer ring) with a spherical concave surface, and rolling elements or sliding pads. The sliding surface is spherical, resulting in a compact overall structure. The shaft ring and seat ring can be tilted relative to each other to achieve angular compensation.
Axial spherical plain bearings are specifically designed to withstand high-purity axial (thrust) loads, possess self-aligning capabilities to compensate for installation eccentricity and shaft deflection; they have a low coefficient of friction, are impact-resistant, insensitive to edge loads, and have a long service life.
