- the other two bearing surfaces 14 and 20 of the bearing surface play are located in opposite corners of the frame 4.
- All bearing surfaces are ideally coplanar. Due to manufacturing tolerances and the search for maximum stability under heavy road traffic, through a triangle as large as possible, they can however be offset from each other by a given maximum offset, which is example 3 mm.
- the maximum offset determined is the distance, measured perpendicularly to the P-P frame plane, between the two bearing surfaces having the greatest mutual distance perpendicular to the P-P frame plane.
