The Task: A mobile camera crane, which is mounted on vehicles, is to be rotated pivotally. The bearing has to cope with high tilting moments due to the boom. Lightweight construction and robustness against impacts and vibrations are further requirements for the bearing.
The Solution: Bearing assembly with weight-reducing bores and a round wire without raceway. The holes reduce the weight by almost 50%. The round wire can not tilt under load and ensures full function of the bearing even when twisting the mating structure.
