The BGL OH HE hydraulic sleeve is a fastening component that helps you mount and dismount bearings on medium and large shafts. Its internal and external oil channels let you inject pressurized oil to simplify these tasks, especially on critical fits. It is designed for shaft diameters from 140 mm and up.
The part number tells you the series and the bearing bore. For example, OH30/710HE means a series 30 sleeve for a 710 mm bearing bore, while OH31/630HE is series 31 for a 630 mm bore. The HE suffix shows that the oil connection is on the outer side. The range includes sizes from OH30/710HE through OH39/600HE, with options for various diameters.
You will find these sleeves in steel mills, cement plants, mining operations, paper machines, and large-scale mills. They are common in crushing equipment, rotary kilns, conveyor belts, and other large machines where bearings need to be mounted and dismounted often. The oil channels speed up maintenance and reduce the risk of damaging the shaft or bearing during these procedures.
When selecting a sleeve, match the shaft diameter and the series that fits your bearing. For installation, clean the surfaces, apply pressurized oil through the channels, and check alignment. Hydraulic oil is essential to distribute pressure evenly. During dismounting, the oil film helps extract the sleeve without impacts. Always follow the manufacturer's recommendations for oil pressure and procedure.
Other manufacturers make hydraulic sleeves with similar functions, but dimensions and channel arrangements can differ. If you are replacing an existing sleeve, the safest approach is to identify the original part number and consult with us. We can help you find a compatible part based on dimensions or the associated bearing part number.

Frequently asked questions
- What does the HE suffix mean in BGL sleeves?
- The HE suffix indicates that the oil channel is on the outer side of the sleeve. This allows you to connect the oil pump for mounting and dismounting. Respect this configuration to ensure correct pressure distribution.
- For what shaft diameters are these sleeves recommended?
- They are designed for medium and large shafts, from 140 mm and up. The OH series covers a wide range of sizes, and each part number corresponds to a particular diameter. Contact us with your shaft dimension to identify the right sleeve.
- How is a hydraulic sleeve mounted?
- Mounting involves cleaning the shaft and the sleeve, applying pressurized oil through the channels, and sliding the sleeve into position. Verify alignment and follow the manufacturer's recommended pressures to avoid damage. Dismounting is easier because the oil injection creates a lubricating film.
