Selecting CRBT / RAU bearings

Browse the 5 mm wide bearing family for compact rotary mechanisms. This category groups the existing CRBT-labelled table and its RAU reference designations. Select from the actual dimensions in the table: a similar series name alone does not establish interchangeability.

  • Bore, outside diameter and the 5 mm axial envelope
  • Shoulder diameters and chamfer clearance
  • Clearance or preload, lubrication and runout requirement

The RAU category below covers the separate RA-dimensional family with 8 mm and 13 mm widths. Compare the related series.

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.
