Description
BGL AOH2256GG belongs to hydraulic sleeve, part of our Bushings and sleeves range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for AOH2256GG and any equivalents.
The BGL AOH GG hydraulic sleeve mounts on the shaft to help install and remove bearings and other interference-fit components. Internal passages let you inject pressurized oil and form a film that lowers friction, so maintenance on medium and large shafts becomes more manageable.
The part number tells you the size. Take AOH32/530GG, AOH39/500GG or AOH39/670GG: AOH marks the hydraulic withdrawal sleeve family, the first number after the slash is the shaft diameter, the second number is the outside diameter or nominal size of the matching bearing, and GG means the sleeve has oil injection channels. These references fit bearings with bores from 500 to 670 mm, on shafts that are slightly smaller.
Use this sleeve where large rotating equipment needs accurate mounting and removal without damage: steel, cement, mining, power generation, paper and milling operations. It appears in gearboxes, ball mills, rotary kilns, presses and other heavy machines. Injecting oil under pressure shortens maintenance shutdowns and lowers the chance of scoring the shaft or bearing during removal.
To pick the right hydraulic sleeve, check the shaft size and the bore diameter of the bearing or part. Choose the AOH GG series when the fit is interference and you expect to dismount the part often. At mounting, confirm alignment, make sure the oil channels are clean, and use oil with a viscosity suited to the working pressure. Lubricating the contact surfaces beforehand and watching the injection pressure help prevent deformation.
Hydraulic sleeves from different makers often follow similar designations, but suffixes and tolerances can differ. If you have another brand's part number, an equivalent BGL reference can usually be found while keeping the shaft size and outside diameter. Always check the critical dimensions and channel type before replacing a part, so it works with the existing bearing.

Frequently asked questions
- How does an AOH GG hydraulic sleeve differ from a standard withdrawal sleeve?
- The AOH GG sleeve has internal channels for injecting pressurized oil, which makes mounting and dismounting easier by cutting friction. A standard withdrawal sleeve lacks these channels and needs more mechanical effort to remove the part.
- How do I select the right hydraulic sleeve size?
- Identify the shaft diameter and the bore diameter of the bearing or part. The AOH GG designation includes these sizes: for example, AOH32/530GG matches a bearing with a 530 mm bore, and the shaft is somewhat smaller. If unsure, send us the dimensions and we will quote the exact reference.
- Can a hydraulic sleeve be reused after dismounting?
- Yes, as long as it shows no deformation, channel wear or thread damage. Before reusing, check that the oil channels are clean and the contact surfaces have no marks. A sleeve in good condition can handle several mounting and dismounting operations.
