Product Overview: The H 3068 OH Adapter Sleeve
The H 3068 OH is a high-performance adapter sleeve designed for securely mounting bearings with a tapered bore onto cylindrical shafts with a 320mm diameter. As a crucial component in our Adapter Sleeves collection, this sleeve is part of the specialized OH Series, which is distinguished by its integrated oil supply ducts. These ducts facilitate hydraulic mounting and, more importantly, dismounting, making the process significantly easier and safer, especially in large-scale industrial applications. The H 3068 OH ensures a precise and firm fit, preventing slippage and ensuring optimal bearing performance and longevity.
Manufactured to meet rigorous industry standards, this adapter sleeve assembly includes the sleeve itself, a corresponding lock nut, and a lock washer. It provides a cost-effective and reliable solution for locating bearings on smooth or stepped shafts, eliminating the need for complex shaft machining.

Key Features of the H 3068 OH Sleeve
- Hydraulic Mounting/Dismounting: Features oil ducts and grooves that allow for the injection of oil under high pressure, simplifying installation and removal.
- Complete Assembly: Supplied as a complete set including a high-strength lock nut and a secure lock washer for immediate installation.
- Precision Machining: Ground with high precision to ensure accurate geometry for a tight, concentric grip on the shaft.
- Slotted Design: The sleeve is slotted and has an external taper, which allows it to contract and grip the shaft securely when driven into the bearing bore.
- Facilitates Use of Standard Shafts: Allows for the use of commercially available smooth shafts, reducing machining costs and complexity.
- Versatile Compatibility: Designed for use with various bearing types with a tapered bore, including spherical roller, self-aligning ball, and CARB toroidal roller bearings.
Common Applications
- Mining and Quarrying: Used in large crushers, vibrating screens, and conveyor systems where robust shaft mounting is critical.
- Pulp and Paper Mills: Essential for mounting bearings on the large rolls and drums found in paper processing machinery.
- Large Industrial Fans and Blowers: Provides a secure mounting solution for the main shafts of heavy-duty ventilation systems.
- Steel Manufacturing: Employed in rolling mills and continuous casting machines that operate under extreme loads and temperatures.
- Marine Propulsion Systems: Used for mounting bearings on propeller shafts and in large gearbox assemblies.
- Power Generation: Applied in turbines, generators, and other large rotating equipment requiring reliable bearing fixation.
Benefits of Using the H 3068 OH
- Simplified Maintenance: The hydraulic feature drastically reduces the time and effort required for dismounting bearings, minimizing machine downtime.
- Enhanced Safety: Eliminates the need for heavy hammering or pullers during dismounting, reducing the risk of injury to personnel and damage to components.
- Secure and Reliable Fit: Provides a strong, 360-degree interference fit, ensuring the bearing is firmly locked in its axial position on the shaft.
- Cost-Effective Solution: Reduces the need for special shaft shoulders, keyways, or other locking mechanisms, lowering overall manufacturing and assembly costs.
- Extended Bearing Life: A proper and secure mounting prevents micro-movements between the bearing and shaft, reducing fretting corrosion and extending service life.
- Accommodates Shaft Tolerances: Can be used on shafts with wider commercial tolerances compared to direct-mounted bearings.
