The BGL OHA HE series hydraulic sleeve is a fastening element placed between shaft and hub to transmit torque without a key. Unlike the conventional adapter sleeve, it has inner and outer channels that allow pressurized oil to be injected, making mounting easier and, above all, dismounting on large-diameter shafts. It is recommended for medium and large shafts, from 140 mm.

The OHA HE series designation is read in parts: the letters OHA identify the type of hydraulic sleeve, and the number that follows indicates the bore diameter and the width in millimeters. For example, OHA3032HE corresponds to a sleeve for a 30 mm shaft and 32 mm width; OHA3034HE and OHA3036HE share the same diameter but vary in length. The HE suffix indicates that the oil channel is on the outer side, which defines the injection position during mounting and dismounting.

These sleeves are used in applications requiring a fixed and removable joint between shaft and hub, especially when access with impact tools is limited. Industries such as metallurgy, cement, mining and machine tools use them in gearboxes, couplings, flywheels, pulleys and sprockets. In Argentina, they are common in grinding equipment, presses and large transmissions, where damage-free dismounting is critical.

To select the correct hydraulic sleeve, take into account the shaft diameter, the hub width and the torque to be transmitted. The shaft and bore surfaces must be clean, free of burrs and with the appropriate roughness. During mounting, oil is injected under pressure through the channels to slightly expand the sleeve and make sliding easier; then the pressure is released and the fastening holds firm by interference. It is essential to align shaft and hub before pressurizing and to use the oil recommended by the manufacturer.

As for equivalents, OHA HE series hydraulic sleeves can be interchanged with products from other brands that follow the same standard for dimensions and oil channels. If the customer has a part number from another source, at MR Accesorios Industriales we quote it and tell you the compatible alternative. Interchangeability depends on the tolerances and the type of channel, so it is always best to verify the full designation.

To receive an accurate quote, send the full part number of the sleeve you need on WhatsApp, for example OHA3032HE or OHA3134HE, or the shaft and hub dimensions. At MR Accesorios Industriales we quote the exact part number or size and advise you so the selection is correct. Write to us and we will reply shortly.
