Individual model pages are being added. Use the series table or send the complete model number and drawing for review.

Drawing and reference information

The current LYDL table covers 10–95 mm bores and 21–106 mm outside diameters. Its CRBT designations must not be treated as confirmation of an IKO standard model; verify the complete cross-reference and supplied drawing.

Technical reference: THK RAU family information. 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.
