Product Overview: The H 3268 OH Hydraulic Adapter Sleeve
The H 3268 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto 340mm cylindrical shafts. As a key component in our OH 3200 Series, this sleeve simplifies the installation and removal of large bearings by utilizing hydraulic pressure. The 'OH' designation signifies that it is equipped with oil supply ducts and distribution grooves, allowing for the oil injection method which significantly reduces the force required for mounting and dismounting, thereby preventing damage to both the bearing and the shaft.
This adapter sleeve assembly includes a precision-engineered sleeve, a corresponding lock nut, and a lock washer, providing a complete solution for securing bearings firmly in place. It is an indispensable component in heavy-duty industrial applications where reliability and ease of maintenance are paramount. Explore our comprehensive range of Adapter Sleeves to find the ideal mounting solution for your machinery.
Key Features of the H 3268 OH
- Hydraulic Mounting/Dismounting: Features integrated oil ducts and grooves for easy, low-force, and accurate mounting using the oil injection method.
- Complete Assembly: Supplied as a set including the sleeve, a high-strength lock nut, and a secure lock washer.
- Tapered Design: Ensures a strong and uniform interference fit between the bearing's inner ring and the shaft.
- Split Sleeve Construction: The longitudinal slit allows for easy installation and clamping onto the shaft.
- Versatile Positioning: Enables the bearing to be positioned at any point along a smooth cylindrical shaft.
- High-Quality Steel: Manufactured from durable materials to withstand high mounting forces and operational loads.
Common Applications
- Mining and Quarrying: Used in large crushers, grinding mills, and conveyor systems where heavy bearings are common.
- Pulp and Paper Mills: Essential for mounting bearings on large rollers and drums.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other heavy machinery.
- Large Fans and Blowers: Secures bearings in industrial ventilation systems that operate under continuous, heavy loads.
- Marine and Offshore: Utilized in propeller shafts and rudder systems for reliable performance in harsh environments.
- Power Generation: Found in turbines, gearboxes, and generators requiring robust bearing arrangements.
- Construction Equipment: Supports rotating components in heavy-duty machinery like excavators and cranes.
Benefits of Using the H 3268 OH
- Simplified Maintenance: The hydraulic method makes the otherwise difficult task of dismounting large bearings fast and straightforward.
- Prevents Component Damage: Eliminates the need for hammers or excessive force, protecting the shaft and bearing from damage during installation and removal.
- Enhanced Operational Reliability: Provides a secure and precise fit, reducing vibration and improving the overall stability of the rotating assembly.
- Reduced Downtime: Speeds up maintenance procedures, getting critical machinery back online faster.
- Cost-Effective Shafting: Allows for the use of commercially available smooth shafts, avoiding the cost and complexity of stepped or specially machined shafts.
- Accurate Mounting: The oil injection method allows for precise control over the final position and fit of the bearing.
