The BGL AOH GG series hydraulic sleeve is a mounting and dismounting component placed on the shaft to facilitate the installation and removal of bearings and other parts with an interference fit. Unlike the conventional withdrawal sleeve, it incorporates internal channels that allow pressurized oil to be injected, creating a film that reduces friction and simplifies maintenance tasks on medium and large shafts.

The designation of the AOH GG series is interpreted from its examples: AOH32/530GG, AOH39/500GG or AOH39/670GG. The letters AOH identify the hydraulic withdrawal sleeve family; the two digits after the slash indicate the shaft diameter on which they are mounted, and the number after the slash corresponds to the outside diameter or the nominal size of the associated bearing. The GG suffix indicates the variant with channels for oil injection. These references cover bearings with bores from 500 to 670 mm, mounted on somewhat smaller shafts.

This type of sleeve is used in industries where large rotating equipment requires precise mounting and damage-free dismounting: steel plants, cement plants, mining, power generation, paper mills and mills. In Argentina, it is commonly found in gearboxes, ball mills, rotary kilns, presses and large machines. The ability to inject pressurized oil speeds up maintenance shutdowns and reduces the risk of marking the shaft or bearing during removal.

To select the correct hydraulic sleeve, take into account the shaft size and the bore diameter of the bearing or part to be mounted. The AOH GG series is chosen when the fit is an interference fit and frequent dismounting is required. During mounting, verify the alignment of the assembly, the cleanliness of the oil channels and the use of an oil with suitable viscosity for the working pressure. Prior lubrication of the contact surfaces and control of the injection pressure are key to avoiding deformation.

Regarding equivalents, hydraulic sleeves are designated similarly among different manufacturers, although suffixes or tolerances may vary. If you have the part number of another brand, it is possible to find the equivalent BGL reference while keeping the shaft size and outside diameter. It is always advisable to verify the critical dimensions and the type of channels before replacing a part, to ensure functional compatibility with the existing bearing.
