The H series adapter sleeve is the component that allows mounting a bearing with a tapered bore onto a cylindrical shaft. It is placed between the shaft and the bearing, and with the corresponding lock nut and lock washer the necessary radial fit is achieved. MR Accesorios Industriales carries this TIMKEN line in Buenos Aires, Argentina.

The H series designation is read with the letter H followed by a three- or four-digit number that identifies the sleeve size. For example, H305, H306, H307, H308, H309, H310, H311 and H312 cover increasing shaft diameters. The numeric suffix does not indicate the diameter directly, but correlates with the compatible tapered bearing. To select the correct sleeve, you must start from the bearing and its tapered bore.

These sleeves are used in equipment where the bearing must be mounted on a cylindrical shaft and requires a tapered fit. Typical applications in Argentina: gear reducers and gearboxes, belt conveyors, mills, machines for the food industry, mining equipment and cement plants. Also in industrial fans and large centrifugal pumps. The H series is common in plant maintenance where spherical roller bearings are replaced.

For mounting, verify that the bearing bore is tapered and that the sleeve corresponds to that taper. The lock nut and lock washer must be the right ones for the sleeve. Lubricating the sleeve and the tapered seat makes fitting easier and prevents damage. Shaft alignment and controlled tightening of the nut are key to avoid deforming the bearing. Follow the bearing manufacturer's instructions for internal clearance.

Regarding equivalents, other manufacturers offer sleeves with similar designations, but dimensions and tolerances may vary. It is always advisable to verify interchangeability with the bearing and the shaft. TIMKEN is a brand that MR carries, and we can advise you on compatibility with other brands. If you need an alternative, ask us with the bearing part number and the shaft diameter.
