The BGL OH HTLTL hydraulic sleeve is a mounting component equipped with internal and external oil injection channels. It simplifies mounting and especially dismounting on medium and large shafts, starting at 140 mm. It secures bearings, pulleys, couplings and similar elements, enabling controlled interference fits and removal without surface damage.
The code breaks down as follows: the prefix OH, then the shaft size, and the suffix HTLTL. For instance, OH31/500HTLTL fits a bearing with a 500 mm bore, while OH31/750HTLTL is for a 750 mm bore. The number after the slash gives the shaft diameter in millimeters. The HTLTL suffix denotes the version with oil channels, and the trailing H means the injection channel is on the outer side. This structure lets you pick the right sleeve quickly based on shaft size.
Typical applications include steel, cement, mining, paper, wind power and heavy machinery—operations that demand sturdy assemblies and frequent disassembly. Mills, crushers, conveyor belts, high-flow pumps and process equipment commonly use these sleeves. Injecting oil under pressure cuts the effort needed for extraction, which matters when access is tight and downtime must be kept low.
When selecting a sleeve, check the shaft diameter and the dimensions of the bearing seat or component to be secured. Use suitable equipment for the pressurized oil lubrication and follow the manufacturer's instructions to prevent damage. Before mounting, clean and inspect all surfaces, verify alignment, and apply oil through the correct channels. The H suffix tells you the outer channel is the injection path, which guides mounting.
BGL hydraulic sleeves can replace equivalent products from other brands that share the same dimension standard. For a replacement, compare the full designation, the shaft diameter and the type of oil channels. Interchangeability depends on standardized dimensions, not just the code. If you need help, the technical team at MR Industrial Accessories can assist.

Frequently asked questions
- What does the suffix HTLTL mean in the code OH31/500HTLTL?
- HTLTL indicates the sleeve has internal and external channels for oil injection, which aids mounting and dismounting. The final H specifies that the oil channel is on the outer side. This setup is standard for BGL hydraulic sleeves.
- For what shaft diameters is this sleeve recommended?
- It is intended for medium and large shafts, from 140 mm upward. The OH HTLTL series covers a broad size range, and each code shows the shaft diameter in millimeters. For example, OH31/500HTLTL is for a bearing with a 500 mm bore.
- How are mounting and dismounting carried out with this sleeve?
- Oil is injected under pressure through the provided channels, creating a lubricating film that lowers friction. This allows interference mounting and dismounting without harming the shaft or component. Always follow the manufacturer's instructions and use suitable injection equipment.
