Drawing and reference information

LXII-style LYDL table designations and XI reference numbers require an approved cross-reference. Matching the family letters alone is not sufficient.

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.
