Pivot mounting with spherical plain bearing
Mounting of hydraulic cylinders
A cylinder mounting with two degrees of freedom is referred to as pivot mounting with spherical plain bearing. This enables pivoting installation of the cylinder.
By additionally mounting a spherical rod eye on the piston rod, the cylinder can be extended to an axis with 2 hinges.
The cylinder force is applied centrally to the cylinder axis through the hinge eye, so that no side loads arise due to bracing.
A spherical plain bearing requiring maintenance is standardly installed in the hinge eye.
You can find more detailed information about the installed spherical plain bearings here under spherical plain bearings.
Additional mounting accessories, such as flanges, can be attached to the cylinder.
