Product Overview: H 2356 OH Hydraulic Adapter Sleeve
The H 2356 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 280 mm diameter. As a key component in our Adapter Sleeves category, this sleeve simplifies the installation and removal of large bearings, particularly in heavy-duty industrial machinery. It is part of the robust H 2300 Series and the specialized OH Series, which incorporates oil ducts for hydraulic mounting and dismounting.
This hydraulic method allows for precise, secure, and damage-free installation, ensuring a strong interference fit without the need for excessive force. The H 2356 OH assembly typically includes the sleeve, a lock nut, and a locking device, providing a complete solution for securely locating bearings on a shaft. It is an essential accessory for applications demanding high reliability and easy maintenance, commonly used with large Spherical Roller Bearings.
Key Features of the H 2356 OH Sleeve
- Hydraulic Mounting/Dismounting: Features oil supply ducts and distribution grooves for the hydraulic method, simplifying the installation and removal of large bearings.
- For 280 mm Shafts: Precisely manufactured to fit standard 280 mm cylindrical shafts.
- Secure Bearing Location: Enables bearings to be accurately positioned and secured anywhere on a plain shaft, eliminating the need for shaft shoulders.
- Complete Assembly: Supplied as a complete unit with a lock nut and locking washer for a secure and reliable fit.
- High-Strength Construction: Manufactured from high-quality steel to withstand high mounting forces and operational loads.
- Concentric Fit: Ensures an even and tight grip on the shaft, which helps to maintain rotational accuracy and reduce vibration.
Common Applications
- Mining and Construction: Used in heavy equipment like crushers, vibrating screens, and conveyor pulleys where large bearings are subjected to extreme loads.
- Pulp and Paper Industry: Essential for mounting bearings on the large rollers found in paper machines and processing equipment.
- Industrial Fans and Blowers: Provides a reliable mounting solution for large fan shafts, ensuring stability and ease of maintenance.
- Marine and Offshore: Applied in propulsion systems and deck machinery where robust and serviceable bearing arrangements are critical.
- Power Generation: Used in turbines, generators, and large gearboxes that require precise and secure bearing mounting.
- Steel Manufacturing: Supports rollers in continuous casting machines and rolling mills, facilitating quick bearing replacement.
Benefits of Using the H 2356 OH Sleeve
- Simplified Installation and Removal: The hydraulic method significantly reduces the physical effort and time required for mounting and dismounting large bearings.
- Prevents Component Damage: Eliminates the need for hammers or presses, minimizing the risk of damage to the bearing, shaft, or housing.
- Enhanced Operational Reliability: Achieves a powerful and uniform interference fit, preventing fretting corrosion and ensuring the bearing operates as intended.
- Cost-Effective Shaft Design: Allows for the use of simpler and more economical plain shafts rather than stepped shafts with shoulders.
- Improved Maintenance Efficiency: Drastically simplifies the dismounting process, reducing machine downtime during servicing or replacement.
- Precise Clearance Adjustment: Facilitates accurate setting of the bearing's radial internal clearance during the mounting process for optimal performance.
