Product Overview: The H 3272 OH Hydraulic Adapter Sleeve
The H 3272 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a 360mm tapered bore onto a 340mm cylindrical shaft. As a crucial component in our Adapter Sleeves range, this sleeve is part of the specialized OH 3200 Series, which features integrated oil supply ducts and distribution grooves. This design facilitates the use of the oil injection method, allowing for effortless and safe mounting and dismounting of large bearings without causing damage to the bearing or the shaft. The sleeve, along with its corresponding lock nut and washer, ensures a secure and precise fit, simplifying the assembly of heavy-duty machinery.
Key Features of the H 3272 OH
- Hydraulic Mounting and Dismounting: Equipped with oil ducts and grooves for the oil injection method, significantly reducing the force required for installation and removal.
- Precise Shaft Adaptation: Enables the use of a bearing with a 360mm tapered bore on a standard 340mm cylindrical shaft.
- Secure Clamping: The sleeve is slit and tapered to provide a powerful, concentric grip on the shaft when the lock nut is tightened, preventing slippage.
- High-Strength Construction: Manufactured from high-quality steel to withstand high mounting forces and operational loads, ensuring long-term reliability.
- Complete Mounting System: Designed to be used with a lock nut (e.g., HM 3272) and a locking device for a full, secure assembly.
- Simplifies Machine Design: Allows for the use of straight shafts, which are less complex and more economical than stepped shafts.
Common Applications
- Mining and Quarrying: Used in heavy equipment like rock crushers, conveyor belt pulleys, and grinding mills where large bearings are common.
- Pulp and Paper Industry: Essential for mounting bearings on large rollers in paper machines and processing equipment.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other machinery operating under extreme loads.
- Power Generation: Suitable for turbines, large generators, and gearboxes where reliable bearing mounting is critical.
- Marine and Offshore: Used in propeller shaft arrangements and other large-scale marine propulsion systems.
- Industrial Fans and Blowers: Provides a secure mounting solution for large-diameter fan shafts in ventilation systems.
- Construction Machinery: Employed in heavy-duty equipment such as excavators and cranes.
Benefits of Using the H 3272 OH
- Reduced Downtime: The hydraulic method dramatically speeds up the maintenance process of mounting and dismounting bearings.
- Prevents Damage: Eliminates the risk of scoring or damaging the bearing bore and shaft surface, which can occur with mechanical methods.
- Improved Safety: Avoids the need for heavy hammers or excessive force, creating a safer working environment for maintenance personnel.
- Enhanced Operational Reliability: Achieves a precise and uniformly tight fit, reducing vibrations and improving the overall stability of the rotating assembly.
- Cost-Effective Maintenance: Reduces labor costs and extends the service life of both the bearing and the shaft by ensuring proper installation.
- Versatility: Allows bearings to be easily positioned at any point along a plain shaft, offering greater design flexibility.
