Product Overview: The H 3156 OH Hydraulic Adapter Sleeve
The H 3156 OH is a high-precision hydraulic adapter sleeve designed for mounting bearings with a 280 mm tapered bore onto a 260 mm cylindrical shaft. As a crucial component in our Adapter Sleeves category, this sleeve simplifies the installation and removal of large bearings through hydraulic pressure. It is part of the robust OH 3100 Series, which features integrated oil supply ducts and distribution grooves, allowing for the application of the oil injection method. This significantly reduces the force required for mounting and dismounting, minimizing the risk of damage to both the bearing and the shaft.
Manufactured to exacting standards, the H 3156 OH adapter sleeve ensures a secure and concentric fit, which is essential for the optimal performance and service life of heavy-duty rotating machinery. This assembly typically includes the sleeve, a corresponding lock nut, and a lock washer, providing a complete solution for demanding industrial applications.
Key Features of the H 3156 OH
- Hydraulic Assist: Features built-in oil ducts for hydraulic mounting and dismounting, making the process faster and safer.
- Secure Clamping: Provides a strong, reliable interference fit between the bearing and the shaft.
- Precision Machined: Ensures high dimensional and geometric accuracy for consistent and reliable performance.
- Complete Assembly: Supplied with a lock nut and locking device for a full mounting solution.
- Facilitates Easy Dismounting: The oil injection method allows for effortless removal of bearings, even after long periods of operation.
- Versatile Application: Enables the use of standard cylindrical shafts for bearings with tapered bores, offering design flexibility.
Common Applications
- Mining and Quarrying: Used in crushers, conveyors, and heavy-duty gearboxes where large bearings are subjected to extreme loads.
- 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 high-temperature, heavy-load machinery.
- Power Generation: Suitable for turbines, large generators, and industrial gear units that require reliable bearing arrangements.
- Marine and Offshore: Used in ship propulsion systems, thrusters, and deck machinery where robust mounting is critical.
- Large Industrial Fans and Blowers: Ensures secure mounting of bearings in large-scale ventilation and air-handling systems.
Benefits of Using the H 3156 OH
- Reduced Installation Time: Hydraulic mounting is significantly faster than traditional mechanical methods, reducing equipment downtime.
- Prevents Component Damage: Eliminates the need for excessive force or heating, protecting the bearing and shaft from damage during installation and removal.
- Enhanced Operational Reliability: A proper and secure fit extends bearing service life and improves the overall reliability of the machinery.
- Simplified Maintenance: Easy dismounting streamlines bearing replacement and other maintenance tasks.
- Increased Safety: The hydraulic method is a controlled process that is safer for technicians compared to using hammers and brute force.
- Cost-Effective Solution: Allows for the use of less expensive, straight cylindrical shafts instead of stepped shafts, reducing overall manufacturing costs.
