Drawing and reference information

A/B/C/D and gear symbols are drawing-dependent. Unclear or blank legacy table entries require drawing confirmation and must not be interpreted as zero.

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.

Request a drawing or quote with the complete model, quantity, loads, speed, duty cycle and mounting requirements.
