NTN adapter sleeves

NTN adapter sleeves belong to the connection between shaft and bearing. This line includes sleeve references and designations that combine a bearing with its mounting reference. That distinction matters when preparing an order: a combined code should not automatically become a request for a complete assembly. Establish which part needs replacement and which parts remain in the machine first.

Identifying the designation

The catalog includes H 220X, H30/500 and 1205SK;H 205X. The first retains the space between letter and number as well as the final X; the second contains a slash within its numeric block. In the third, a semicolon separates two related references. Copy the entire marking and specify whether it comes from the sleeve, bearing or assembly documentation. Do not convert these numbers into shaft dimensions or interpret endings without the corresponding technical record.

Position and surrounding assembly

Identify the sleeve at the bearing seat on the shaft. When reviewing a fan, conveyor or transmission position, describe how the assembly is retained and which side allows access. NTN withdrawal sleeves occupy another line; nuts and lock washers are also identified separately. These fastening parts serve different functions, and a similar outside measurement does not establish compatibility. A drawing of the position helps distinguish them before dividing the request into components.

Information for a quote

Send the code, shaft diameter, sleeve measurements, photographs of both ends and application to MR Accesorios Industriales. Add the bearing designation and an image of the nut or retention arrangement. For a drawing-based request, mark the position and clarify which items it includes. This information allows a specific reference to be reviewed while separating the requested replacement from parts used only for identification.

Does a semicolon code include the whole assembly?

Do not assume that it does. Specify the component required and attach the assembly detail to define the scope of the request.

Is measuring the shaft enough?

It is a starting point. The bearing reference, sleeve measurements and retention arrangement are also needed.

Can I leave out the final X?

Keep it exactly as marked. Identification uses the full reference without assigning a technical meaning to that ending here.

Main series

NTN Adapter Sleeve

The adapter sleeve is a mounting component that secures bearings with a tapered bore onto cylindrical shafts. It consists of a tapered sleeve and a lock nut with a lock washer, which when tightened generates the necessary interference to secure the bearing. It is used in equipment requiring a robust and removable connection, such as gearboxes, conveyors and process machinery. MR Accesorios Industriales sells NTN adapter sleeves in Buenos Aires, Argentina.

NTN H Series Adapter Sleeve

The NTN H series adapter sleeve is a mounting component used to secure bearings with a tapered bore onto cylindrical shafts. It consists of a split sleeve and a lock nut with a lock washer, which allows precise fitting and easy disassembly. It is a key part in power transmission, since it guarantees concentricity and prevents axial displacement of the bearing.
