Product Overview: The H 3280 OH Hydraulic Adapter Sleeve
The H 3280 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 400mm diameter. As a critical component in our Adapter Sleeves range, this sleeve is part of the OH 3200 Series, which features integrated oil ducts for hydraulic mounting and dismounting. This system simplifies the installation of large bearings, significantly reducing the required force and preventing damage to both the bearing and the shaft.
Manufactured to precise standards, the H 3280 OH ensures a secure and concentric grip, facilitating the reliable operation of heavy-duty machinery. The sleeve is supplied complete with a corresponding lock nut and lock washer, providing a full assembly for locating bearings axially on a shaft. Its robust design is essential for demanding industrial environments where performance and ease of maintenance are paramount.
Key Features of the H 3280 OH
- Hydraulic Mounting Capability: Features oil supply ducts and distribution grooves that allow oil to be injected between the mating surfaces, simplifying the mounting and dismounting process.
- Complete Assembly: Supplied as a set with a high-quality lock nut and lock washer for secure axial positioning of the bearing.
- Precision Taper: Engineered with a precise 1:12 taper to ensure a tight, uniform fit between the bearing's inner ring and the shaft.
- Slotted Design: The sleeve is longitudinally slotted to allow for contraction, ensuring a firm grip on the shaft when the lock nut is tightened.
- High-Strength Material: Constructed from durable, high-quality steel to withstand high mounting forces and operational loads.
- Versatile Application: Enables the use of standard cylindrical shafts, which are more economical and easier to source than stepped shafts.
Common Applications
- Mining and Construction: Used in heavy equipment like crushers, conveyors, and excavators where large bearings are common.
- Pulp and Paper Mills: Ideal for machinery such as rollers and drying cylinders that operate under heavy loads and require frequent maintenance.
- Industrial Fans and Blowers: Ensures secure mounting of bearings in large-scale ventilation systems.
- Marine and Offshore: Applied in propulsion systems, winches, and cranes that require robust and reliable bearing arrangements.
- Steel Manufacturing: Essential for mounting bearings in rolling mills and continuous casting machines.
- Power Generation: Used in turbines, generators, and large gearboxes to facilitate secure and precise bearing location.
Benefits of Using the H 3280 OH Sleeve
- Simplified Installation and Removal: The hydraulic feature dramatically reduces the time and effort needed for mounting and dismounting large bearings.
- Prevents Component Damage: Eliminates the need for excessive force or heating during installation, safeguarding the integrity of the bearing and shaft.
- Enhanced Operational Reliability: Provides a secure, 360-degree contact fit, which minimizes vibration and improves the overall stability of the rotating assembly.
- Cost-Effective Shafting: Allows for wider tolerances on the shaft diameter and eliminates the need for expensive and complex stepped shafts.
- Improved Maintenance Efficiency: Speeds up the process of bearing replacement, reducing machinery downtime and associated maintenance costs.
- Accurate Bearing Positioning: Allows for precise and adjustable axial placement of the bearing on the shaft, ensuring optimal performance.
