The BGL OH...HTL hydraulic sleeve is a fastening element with internal and external oil channels. These allow pressurized oil to be injected, which simplifies installation and, more importantly, removal on medium and large diameter shafts. It is used to secure bearings, pulleys, couplings, and similar components, particularly where frequent disassembly or precise fitting is required. MR Industrial Accessories supplies this line.
The OH...HTL code can be broken down as follows: OH denotes the hydraulic adapter sleeve series; the following number indicates the bearing size. In OH31/950HTL, the digits after the slash represent the bore in millimeters. In OH3144HTL, the last two digits multiplied by 5 give the bore (220 mm). The HTL suffix means the sleeve has an oil channel on the outer side, enabling oil injection for mounting and dismounting. Examples such as OH31/1000HTL, OH31/1060HTL, OH3148HTL, OH3152HTL, OH3156HTL, and OH3160HTL illustrate the range of sizes in this series.
These sleeves are found in steel, cement, mining, paper, and power generation industries, where large diameter shafts demand mounting methods that minimize damage risk and allow clean removal. They also appear in grinding equipment, rotary kilns, conveyor belts, and large machines.
When selecting a sleeve, consider the shaft diameter and the dimensions of the bearing or component to be fastened. Lubrication with pressurized oil is critical: it is injected through the channels to create a film that reduces friction during mounting and dismounting. Proper alignment and adherence to the manufacturer's procedure are essential to avoid deformation. Sealing and surface cleanliness also affect the outcome.
Hydraulic sleeves from different manufacturers can be interchanged if the main dimensions and oil channel type match. Always verify the complete designation and dimensions before replacing a part. If you have a part number from another brand, we can help you find the equivalent BGL reference.

Frequently asked questions
- What distinguishes a hydraulic sleeve from a standard adapter sleeve?
- The hydraulic version includes internal and external channels for injecting oil under pressure. This eases mounting and especially dismounting, which is crucial on large shafts with tight fits. A standard adapter sleeve lacks these channels.
- For which shaft diameters is the BGL OH...HTL sleeve suitable?
- It is intended for medium and large shafts, starting at 140 mm and above. The series offers various sizes; contact us for the one you need and we will provide a quote.
- How do mounting and dismounting work with oil under pressure?
- Oil is injected through the sleeve channels to form a lubricating film that lowers friction. The component is then positioned and pressure released. For dismounting, the process is repeated, which helps prevent damage to the shaft and bearing.
