Product Overview: The H 3260 OH Hydraulic Adapter Sleeve
The H 3260 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a 300mm tapered bore onto a 280mm cylindrical shaft. As a key component in our Adapter Sleeves collection, this sleeve is part of the specialized OH Series, which facilitates exceptionally easy and secure mounting and dismounting of large bearings using hydraulic pressure. The integrated oil ducts and distribution grooves allow for the application of oil under pressure, expanding the sleeve and simplifying the installation process, thereby preventing damage to the bearing and shaft. This sleeve comes complete with a corresponding lock nut and locking device for a secure and reliable assembly.
Key Features of the H 3260 OH
- Hydraulic-Assisted Mounting: Features built-in oil supply ducts and grooves to enable the oil injection method, significantly reducing the force required for installation.
- Precise and Secure Fit: The tapered design ensures a tight interference fit, securely locking the bearing onto the shaft for optimal performance under heavy loads.
- Complete Assembly: Supplied as a full set including the sleeve, a high-strength lock nut, and a locking washer, providing all necessary components for a secure fastening.
- Damage-Free Dismounting: The hydraulic system also simplifies bearing removal, allowing the sleeve to be easily disengaged without damaging the bearing or the shaft seat.
- High-Grade Steel Construction: Manufactured from high-quality, dimensionally stable steel to ensure durability, reliability, and consistent performance in demanding industrial environments.
- Standardized Dimensions: Produced to industry-standard specifications for full interchangeability and compatibility with corresponding bearings.
Common Applications
- Rolling Mills: Used to mount large roll-neck bearings in steel and aluminum production.
- Mining and Construction: Ideal for heavy-duty equipment such as crushers, conveyors, and excavators where large bearings are subject to extreme conditions.
- Pulp and Paper Machines: Facilitates the installation of bearings on large rollers in paper processing machinery.
- Wind Turbines: Essential for mounting main rotor shaft bearings, simplifying both installation and in-situ maintenance.
- Marine Propulsion: Used for securing propeller shaft bearings and in other large-scale marine applications.
- Power Generation: Applied in large industrial fans, blowers, and generators that require robust and reliable bearing arrangements.
Benefits of Using the H 3260 OH
- Simplified Installation and Removal: Drastically reduces the time and physical effort required for mounting and dismounting large bearings compared to traditional mechanical or thermal methods.
- Enhanced Operational Safety: The hydraulic method is safer for technicians, minimizing the risks associated with using heavy tools or open flames.
- Prevents Component Damage: Eliminates the risk of scoring or damaging the bearing bore and shaft surface during the fitting process, extending the life of critical components.
- Increased Machine Uptime: Faster and more efficient maintenance procedures lead to reduced downtime and increased productivity.
- Accurate Bearing Positioning: Allows for very precise axial adjustment and positioning of the bearing on the shaft, ensuring optimal load distribution and performance.
- Reliable Performance: Provides a consistently strong and uniform grip on the shaft, preventing fretting corrosion and ensuring stable operation. This sleeve is commonly used with Spherical Roller Bearings like the 22260, 23060, and 24060.
