Product Overview: H 3088 OH Hydraulic Adapter Sleeve
The H 3088 OH is a precision-engineered hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 440mm diameter. As a key component in our OH 3000 Series, this sleeve simplifies the installation and removal of large bearings by utilizing hydraulic pressure. It is part of our comprehensive range of Adapter Sleeves, essential accessories for ensuring secure and accurate bearing placement in demanding industrial environments.
This sleeve features oil supply ducts and distribution grooves, allowing hydraulic fluid to be injected between the mating surfaces. This process creates an oil film that dramatically reduces friction, making it possible to mount and dismount large bearings with minimal force and without causing damage to the bearing or the shaft. The H 3088 OH is an indispensable solution for heavy-duty machinery where reliability and maintenance efficiency are paramount.
Key Features of the H 3088 OH Sleeve
- Hydraulic Mounting Design: Equipped with oil ducts and grooves to facilitate easy, low-force mounting and dismounting using hydraulic pressure.
- Secure Bearing Fit: Provides a strong, concentric grip, securely fastening the bearing to the shaft and ensuring precise alignment.
- Shaft Compatibility: Allows bearings with a tapered bore to be used on standard cylindrical shafts, offering greater design flexibility.
- Robust Construction: Manufactured from high-strength steel to withstand high mounting forces and operational loads, ensuring long service life.
- Reduces Installation Damage: The hydraulic method minimizes the risk of scoring or damaging the bearing bore and shaft seat during installation.
- Complete Mounting System: Designed to be used with a corresponding hydraulic nut and lock washer to achieve the correct interference fit and secure axial location.
Common Applications
- Mining and Cement Industries: Used in large crushers, grinding mills, and conveyor drive pulleys where heavy bearings are common.
- Pulp and Paper Mills: Ideal for mounting bearings on large rollers and drums in paper machines.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other heavy machinery requiring robust bearing arrangements.
- Power Generation: Suitable for turbines, large generators, and gearboxes where precise and reliable mounting is critical.
- Marine Propulsion: Used for mounting bearings on propeller shafts and in large marine gearboxes.
- Industrial Fans and Blowers: Ensures secure mounting of bearings in large-scale ventilation systems subject to high speeds and loads.
Benefits of Using the H 3088 OH
- Simplified Maintenance: Greatly reduces the time and effort required for mounting and dismounting large bearings, minimizing equipment downtime.
- Enhanced Safety: Eliminates the need for traditional methods like hammering or heating, creating a safer working environment for maintenance personnel.
- Improved Reliability: Achieves a precise and uniform interference fit, which enhances bearing performance and operational reliability.
- Extended Component Life: Prevents damage to bearings and shafts that can occur with forceful mechanical mounting techniques.
- Cost-Effective: Reduces labor costs associated with maintenance and prolongs the life of expensive bearings and shafts, leading to lower total ownership costs.
- Accurate Positioning: Allows for exact axial positioning of the bearing on the shaft, which is crucial for optimal machine performance.
