Drawing and reference information

Use the dimensions of the selected table row. A fixed 400 mm bore or 540 mm outside-diameter limit would not describe all entries in the existing LYDL table.

Technical reference: Schaeffler slewing ring catalogue 404. Brand names identify reference families only. Supplied LYDL dimensions, tolerances, load ratings and acceptance requirements are defined by the drawing and quotation agreed for the order.
