The BGL OHA HE hydraulic sleeve connects shaft and hub without a key, using oil pressure to assist assembly and removal. It is designed for medium and large shafts, starting at 140 mm.
The OHA HE code identifies the sleeve type and size: OHA indicates a hydraulic sleeve, the following digits give bore diameter and width in millimeters, and the HE suffix means the oil channel runs on the outer side. For instance, OHA3032HE fits a 160 mm bore, while OHA3034HE and OHA3036HE are for 170 mm and 180 mm bores. The HE position determines where oil is injected during mounting and dismounting.
These sleeves suit applications that need a secure yet removable shaft-hub joint, particularly where impact tools cannot reach. They appear in gearboxes, couplings, flywheels, pulleys and sprockets across metallurgy, cement, mining and machine tool operations, as well as in grinding equipment, presses and large transmissions where damage-free removal matters.
Choosing the right sleeve requires the shaft diameter, hub width and torque to be transmitted. Shaft and bore surfaces must be clean, free of burrs and have the correct roughness. During mounting, pressurized oil passes through the channels to slightly expand the sleeve, allowing it to slide into place; once pressure is released, the interference fit holds it firm. Align shaft and hub before applying pressure and use the oil specified by the manufacturer.
Hydraulic sleeves in the OHA HE series can be interchanged with other brands that share the same dimensional standard and oil channel layout. If you have a code from another source, send it to MR Industrial Accessories and we will quote it and point out a compatible alternative. Tolerances and channel type affect interchangeability, so verifying the full designation is recommended.
To receive an accurate quote, send the complete sleeve code—such as OHA3032HE or OHA3134HE—or the shaft and hub dimensions via WhatsApp or email. Our team quotes the exact code or size and helps you confirm the selection. We reply promptly.

Frequently asked questions
- How does an OHA HE hydraulic sleeve differ from a standard adapter sleeve?
- The OHA HE sleeve includes inner and outer channels for injecting pressurized oil, which makes mounting and dismounting easier. A standard adapter sleeve lacks these channels, so removal from large shafts can be more difficult.
- What shaft sizes is this sleeve intended for?
- The OHA HE series is recommended for medium and large shafts from 140 mm. Smaller diameters use other sleeve lines. If your shaft falls in that range, the hydraulic sleeve is a suitable choice for safe dismounting.
- How do you mount a hydraulic sleeve?
- Clean and align the shaft and hub, inject pressurized oil through the channels to expand the sleeve, slide it into position, then release the pressure. The interference fit secures it. Follow the manufacturer's instructions and use the recommended oil.
