NTN withdrawal sleeves are bearing mounting components. Identify them through the connection between the seat, shaft and axial retaining parts. The line name does not describe an extraction tool or a complete bearing. When maintenance requires a sleeve replacement, separate that request from the bearing and accessories in the same assembly, even if a repair photograph shows them together.

The catalog distinguishes AH 308, AHX 310 and AH 24044H. Each has an initial letter group and a space before the number; the second includes X in the prefix and the third ends in H. These differences belong to the reference and must survive transcription. The final letter is not interpreted here as a mounting capability. Connecting the designation to dimensions requires its technical record or assembly drawing, particularly when the marking is obscured or worn.
For a support position to be dismantled, document the access side, shaft shoulder and axial retention arrangement. The inquiry may concern a gearbox or another machine with supported shafts, but the decisive detail is that seat's configuration. NTN adapter sleeves occupy a different subcategory: sharing the word sleeve establishes no substitution. A nut or washer is not the sleeve, even when its marking is easier to see.
Send the full code, available measurements, shaft diameter, sleeve photograph and application to MR Accesorios Industriales. Include the bearing reference and an assembly image taken before dismantling if one exists. State which parts remain and which need replacement. On a sketch, mark the threaded area and part orientation so the replacement can be compared without confusing its ends or assigning dimensions from an incomplete reading.
Not for replacement identification. Retain the letter group shown on the part or drawing.
This line identifies a mounting component. List separately any bearing or accessory included in the request.
The bearing reference and seat detail help establish the relationship between the components.
