This spherical plain bearing sits at the pivot point of the hydraulic cylinder, allowing the cylinder rod to articulate as the implement moves through its range of travel. It accommodates misalignment between the cylinder and the mounting bracket, transmitting axial and radial loads while maintaining smooth rotation. Wear in the bearing race leads to slop at the cylinder eye, which causes uneven force application and accelerated seal wear on the rod. The bearing is pressed into the cylinder eye; on replacement, ensure the housing bore is clean and free of burrs to avoid distorting the outer race.
