The BGL OHA XH hydraulic sleeve is an adapter sleeve with internal and external channels for injecting oil under pressure. That lubricating film reduces friction and allows mounting and, above all, dismounting the sleeve on the shaft without blows or heating. It is used on medium and large shafts, from 140 mm, and is the solution when subsequent dismounting is critical.
The designation OHA…XH is read in parts: OHA identifies the BGL hydraulic sleeve series; the number that follows, as in OHA2344XH or OHA3148XH, encodes the size; and the suffix XH indicates that the oil channel is on the outer side. That configuration allows oil to be injected from the outside of the sleeve, which simplifies the connection of the manual or hydraulic pump during mounting and dismounting.
In Argentine industry, these sleeves appear in presses, rolling mills, mills, paper machines and mining equipment, where large-diameter shafts require clean and repeatable dismounting. They are also used in gearboxes and power transmission couplings. By injecting oil, the risk of seizure is avoided and the shaft surface is protected, something key when the equipment must return to service quickly.
To select the sleeve, check the shaft diameter and the seat tolerance; the OHA XH series is intended for shafts from 140 mm. Mounting requires absolute cleanliness of the surfaces, low-viscosity oil and a pump that reaches the recommended pressure. Lubrication with clean hydraulic oil is essential for the sleeve to expand and slide without damaging the fit.
When replacing a hydraulic sleeve, compare the main dimensions and the type of oil channel. Equivalent series from other brands may differ in the location of the channel or in the working pressure. If you have the code of the original part, send it: at MR Accesorios Industriales we will quote you the BGL OHA XH sleeve or the alternative compatible with your application.

Frequently Asked Questions
- What is the difference between a standard adapter sleeve and a hydraulic one?
- The hydraulic sleeve has internal and external channels for injecting oil under pressure. This generates a lubricating film that reduces mounting effort and, above all, facilitates dismounting without damaging the shaft or the sleeve. The standard sleeve is mounted and dismounted by mechanical methods.
- For what shaft diameters is the OHA XH sleeve recommended?
- The BGL OHA XH series is recommended for medium and large shafts, from 140 mm. For smaller diameters, other fastening solutions exist. If your shaft is in that range, send us the dimension and we will quote you the corresponding hydraulic sleeve.
- How are mounting and dismounting done with oil under pressure?
- The surfaces are cleaned, an oil pump is connected to the channels and low-viscosity oil is injected until the sleeve expands. Then it is slid into position. To dismount, the injection is repeated and it is extracted without blows. It is essential to follow the pressures recommended by the manufacturer.
