When a shaft must come apart cleanly after years in service, the BGL OHA XH hydraulic sleeve is the adapter that makes it possible. Oil is forced through internal and external channels to create a film that lowers friction, so the sleeve slides on and off without hammering or heat. It is built for medium and large shafts, starting at 140 mm, and is chosen when later dismounting is a priority.
Reading the code helps you specify the right part. OHA marks the BGL hydraulic sleeve family. The digits that follow, as in OHA2344XH or OHA3148XH, set the size. The XH suffix tells you the oil channel is on the outer side. That layout lets you connect a manual or hydraulic pump from outside the sleeve, which keeps mounting and dismounting simple.
These sleeves are common in presses, rolling mills, mills, paper machines and mining equipment, where large-diameter shafts need to be separated cleanly and repeatably. They also appear in gearboxes and power transmission couplings. Injecting oil reduces the chance of seizure and protects the shaft surface, which matters when the equipment has to go back into service quickly.
Selection starts with the shaft diameter and the seat tolerance. The OHA XH series covers shafts from 140 mm. Before mounting, clean all surfaces thoroughly, use low-viscosity oil and a pump that can reach the recommended pressure. Clean hydraulic oil is essential so the sleeve expands and slides without damaging the fit.

Frequently asked questions
- How does a hydraulic adapter sleeve differ from a standard one?
- A hydraulic sleeve includes internal and external channels for oil injection. The oil forms a lubricating film that cuts mounting effort and makes dismounting easier without harming the shaft or the sleeve. A standard sleeve relies on mechanical methods for both operations.
- What shaft sizes suit the OHA XH sleeve?
- The BGL OHA XH series is intended for medium and large shafts from 140 mm upward. Smaller shafts use other fixing options. If your shaft falls in that range, send the dimension and we will quote the matching hydraulic sleeve.
- How is oil pressure used during mounting and dismounting?
- Clean the surfaces, connect an oil pump to the channels and inject low-viscosity oil until the sleeve expands. Slide it into position. For removal, repeat the injection and extract it without blows. Always follow the manufacturer's recommended pressures.
