Product Overview: The H 30/710 OH Hydraulic Adapter Sleeve
The H 30/710 OH is a high-performance hydraulic adapter sleeve designed for the secure and efficient mounting of large bearings with a 710 mm tapered bore onto a 670 mm cylindrical shaft. As a key component in our Adapter Sleeves collection, this sleeve simplifies the installation and removal process, especially in heavy-duty industrial applications. The 'OH' designation signifies its hydraulic capabilities, featuring integrated oil supply ducts and distribution grooves that allow for oil injection. This method, known as the oil injection method, creates a thin film of oil between the mating surfaces, drastically reducing the force required for mounting and dismounting and eliminating the risk of damage to the bearing or shaft.
Part of the specialized OH Series and OH 3000 Series, the H 30/710 OH ensures a precise and powerful interference fit once the oil pressure is released. This component is essential for large machinery where reliability and minimal downtime are critical. It comes complete with the necessary lock nut and lock washer to securely fasten the bearing in its designated axial position.
Key Features of the H 30/710 OH Sleeve
- Hydraulic Mounting and Dismounting: Equipped with oil ducts and grooves for the oil injection method, enabling effortless and damage-free installation and removal.
- Secure Interference Fit: The tapered design ensures a strong, 360-degree grip between the bearing and the shaft, preventing slippage and fretting corrosion.
- Use with Cylindrical Shafts: Allows for bearings with a tapered bore to be mounted on simple, cost-effective cylindrical shafts without the need for shoulders or special machining.
- Full Mounting Solution: Typically supplied as a complete assembly with a high-precision lock nut and locking washer for secure axial positioning.
- High-Strength Construction: Manufactured from high-quality steel to withstand high mounting forces and operational loads, ensuring long-term reliability.
- Facilitates Bearing Clearance Adjustment: The tapered mounting allows for precise control over the bearing's final internal clearance during installation.
Common Applications
- Steel and Aluminum Mills: Used in roll neck bearings and continuous casters where large bearings operate under extreme loads.
- Mining and Cement Industries: Essential for mounting bearings in large crushers, grinding mills, and heavy-duty conveyor systems.
- Pulp and Paper Processing: Applied in paper machine rolls, calendars, and pulpers that require robust bearing arrangements.
- Marine and Offshore: Utilized in ship propeller shafts, rudder stocks, and large gearboxes for reliable power transmission.
- Wind Energy: Critical for mounting main shaft bearings in large wind turbines where maintenance access is challenging.
- Large Industrial Fans and Blowers: Ensures secure and balanced mounting for rotor bearings in demanding air-handling systems.
Benefits of Using the H 30/710 OH
- Reduced Installation Time: The hydraulic method significantly speeds up the mounting process for very large bearings compared to traditional mechanical or thermal methods.
- Prevents Component Damage: Eliminates the need for striking or excessive force, protecting the bearing, shaft, and surrounding equipment during maintenance.
- Enhanced Operational Safety: Provides a more controlled and safer procedure for handling and fitting heavy and large components.
- Increased Machine Uptime: Faster and more reliable maintenance cycles lead to reduced downtime and increased productivity.
- Simplified Maintenance: Makes the dismounting of large, tightly-fitted bearings a straightforward task, simplifying bearing inspection and replacement.
- Cost-Effective Shafting: Enables the use of standard commercial shafts, reducing the overall cost and complexity of the machine design.
