Product Overview: The H 3076 OH Hydraulic Adapter Sleeve
The H 3076 OH is a high-performance adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 360mm diameter. As a key component in our Adapter Sleeves collection, this sleeve simplifies the installation process and ensures a secure, concentric fit. The "OH" designation signifies that this model is equipped with oil supply ducts and distribution grooves, enabling the use of the hydraulic method for mounting and dismounting. This feature is particularly crucial for large bearings, as it significantly reduces the force required and minimizes the risk of damage to the bearing or shaft.
Part of the robust OH 3000 Series, the H 3076 OH is supplied as a complete set, including a high-quality lock nut and a locking washer. This ensures that you have all the necessary components for a reliable and lasting assembly. These sleeves allow bearings to be positioned at any point on a plain shaft, offering design flexibility and cost savings by eliminating the need for shaft shoulders or other locating features.
Key Features of the H 3076 OH
- Hydraulic Mounting Capability: Integrated oil ducts and grooves allow for oil injection, simplifying the mounting and dismounting of large bearings.
- Complete Assembly: Supplied with a corresponding lock nut and locking device for a secure and complete installation.
- Versatile Shaft Positioning: Enables bearings to be located anywhere on a cylindrical shaft, providing flexibility in machine design.
- Precision Machined: Manufactured to tight tolerances to ensure a precise and reliable fit between the bearing and the shaft.
- Facilitates Easy Dismounting: The hydraulic feature makes removal of the bearing straightforward, preventing damage and saving maintenance time.
- Durable Construction: Made from high-strength steel to withstand the demanding conditions of heavy industrial applications.
Common Applications
- Mining and Quarrying: Used in large crushers, grinding mills, and conveyor systems where heavy-duty bearings require secure mounting.
- Pulp and Paper Industry: Essential for mounting bearings on the large rollers found in paper machines and pulp processing equipment.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other machinery operating under extreme loads and temperatures.
- Large Industrial Fans and Blowers: Provides a reliable method for mounting bearings on large fan shafts, ensuring balanced and smooth operation.
- Marine and Offshore: Utilized in propulsion systems, winches, and cranes that require robust and easily serviceable bearing arrangements.
- Power Generation: Found in turbines, generators, and large gearboxes where precise alignment and secure mounting are critical.
Benefits of Using the H 3076 OH Sleeve
- Reduced Installation Time: The hydraulic method dramatically speeds up the mounting process for large bearings compared to traditional mechanical methods.
- Prevents Component Damage: Eliminates the need for excessive force or heating during installation and removal, protecting both the bearing and the shaft.
- Enhanced Operational Security: Provides a strong, reliable interference fit that prevents the bearing from spinning on the shaft under load.
- Cost-Effective Shaft Design: Allows for the use of less expensive plain shafts, as it removes the need for steps, shoulders, or keyways.
- Simplified Maintenance: Greatly eases the dismounting process, reducing downtime and labor costs during inspections or replacements.
- Improved Bearing Performance: Ensures correct and uniform contact between the bearing bore and the sleeve, maximizing the bearing's service life and performance.
