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

The designation of the OHA HE series 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 bearing with a 160 mm bore; OHA3034HE and OHA3036HE are for bores of 170 and 180 mm. The suffix HE 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 where a fixed and removable joint between shaft and hub is required, 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 dismounting without damage is critical.

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

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

To receive an accurate quote, send via WhatsApp the complete code of the sleeve you need, for example OHA3032HE or OHA3134HE, or the shaft and hub dimensions. At MR Accesorios Industriales we quote the exact code or size and advise you so that the selection is the correct one. Write to us and we will reply promptly.
