Static basic load rating C0 (kN)

The static basic load rating C0 (see additional columns) denotes the value with which a rod end can in normal applications with a static load be stressed in the weakest cross-section without being permanently deformed. It represents the permissible radial bearing strain at rest. The basic load ratings quoted have been calculated using the respective material characteristic values and can be verified by tensile experiments at room temperature. The yield point was used to 80%, making the safety factor until yield start 1.25.

The static basic load rating also enables the permissible thrust load to be calculated:

Fa = Fa perm. = p • C0 (kN)

p = < / ~ 0.4 for rod ends K series steel/steel version

Dynamic basic load ratings for rod ends are available on request.

The boring in the steel housing is cylindrically taper-bored from one side and starts from the middle depending on the shape of the ball. This enables a high thrust load towards the ball mug.
