Product Overview: The H 39/710 OH Hydraulic Adapter Sleeve
The H 39/710 OH is a precision-engineered hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 710 mm diameter. As a key component in our Adapter Sleeves range, this sleeve simplifies the installation and removal of large bearings, significantly reducing maintenance time and the risk of component damage. Part of the robust OH 3900 Series, it features integrated oil supply ducts and distribution grooves, allowing hydraulic fluid to be injected between the mating surfaces. This oil pressure expands the sleeve and bearing bore, creating a nearly frictionless surface for effortless mounting and dismounting.
Manufactured from high-strength steel, the H 39/710 OH ensures a secure, concentric grip on the shaft once the hydraulic pressure is released and the lock nut is tightened. This method provides a reliable interference fit without the need for keyways or other shaft modifications, making it an ideal solution for heavy-duty industrial applications.

- Pulp and Paper Industry: Ideal for mounting bearings on large rollers in paper machines, which require periodic maintenance and replacement.
- Steel Manufacturing: Employed in rolling mills and continuous casting machinery that operate under extreme loads and temperatures.
- Marine and Offshore: Suitable for propeller shafts and rudder stocks where reliable and maintainable bearing solutions are essential.
- Power Generation: Used in large turbines, generators, and industrial gearboxes to facilitate secure mounting and easy servicing.
- Cement Plants: Applied in ball mills, kilns, and large fan assemblies that demand high reliability and simplified maintenance procedures.
Benefits of Using the H 39/710 OH
- Reduced Downtime: Drastically cuts down the time required for mounting and dismounting large bearings, improving operational availability.
- Prevents Damage: The hydraulic method eliminates the need for hammers and excessive force, protecting the bearing, shaft, and housing from damage.
- Enhanced Safety: Provides a more controlled and safer installation process compared to traditional mechanical or thermal methods.
- Improved Accuracy: Allows for highly accurate axial positioning of the bearing on the shaft, ensuring optimal performance.
- Extended Component Life: A proper and secure fit reduces vibration and wear, prolonging the service life of both the bearing and the shaft.
- Simplified Logistics: Eliminates the need for heating equipment or complex mechanical pullers, streamlining the maintenance toolkit.
