Clevis brackets can be used to mount cylinders with pivot mountings or rod plain or spherical eyes.

Clevis bracket in angle
Depending on the spherical plain bearing used, appropriate bolt tolerances must be provided.
For example, in round head cylinders of series 160 according to ISO 6020-1 and 250 according to ISO 6022 LO spherical plain bearings according to ISO 12240-1 form W are provided. This applies both to the cylinders themselves and to the rod eyes.
In tie rod cylinders according to ISO 6020-2, on the other hand, DO spherical plain bearings to ISO 12240 Form E are provided.
The associated clevis brackets and bolts are standardized in ISO 8132 for round head cylinders and ISO 8133 for tie rod cylinders.
In order to achieve the required internal bearing clearance, suitable tolerances must be maintained on the housing and the pin.
