Product Overview: The H 2338 OH Hydraulic Adapter Sleeve
The H 2338 OH is a high-performance hydraulic adapter sleeve designed for securely mounting bearings with a tapered bore onto cylindrical shafts with a 170mm diameter. As a key component in our OH Series, this sleeve simplifies the installation and removal process, especially in heavy-duty applications. The 'OH' designation signifies that it is equipped with integrated oil supply ducts, allowing for the use of the hydraulic method for both mounting and, more critically, dismounting. This feature significantly reduces the risk of damage to the bearing and shaft during maintenance.
Supplied as a complete set, the H 2338 OH package includes a precision-engineered sleeve, a corresponding lock nut, and a lock washer. This ensures a secure, concentric grip, preventing loosening under operational vibrations and loads. It is an indispensable part of our Bearing Accessories range, providing a reliable and cost-effective solution for various industrial assemblies.
Key Features of the H 2338 OH
- Designed for 170mm Shafts: Precisely manufactured to fit a 170mm cylindrical shaft, providing a solid foundation for the bearing.
- Hydraulic Mounting/Dismounting: Features oil ducts and grooves ('OH') that enable the use of hydraulic pressure for effortless and damage-free installation and removal.
- Complete Mounting Solution: Comes as a full assembly with a high-quality lock nut and a secure lock washer.
- Simplifies Bearing Location: Allows bearings with a tapered bore to be positioned anywhere on a smooth or stepped shaft without shoulders.
- High Clamping Force: Ensures a strong, reliable fit between the bearing and the shaft, transmitting loads effectively.
- Durable Construction: Made from high-strength steel to withstand demanding operational conditions and ensure long service life.
- Reduces Maintenance Time: The hydraulic feature drastically cuts down the time and effort required for dismounting large bearings.
Common Applications
- Heavy Industrial Fans and Blowers: Used to mount large rotor bearings securely onto drive shafts.
- Conveyor Systems: Ideal for securing drum pulley bearings in mining, aggregate, and logistics industries.
- Pulp and Paper Mills: Facilitates the mounting of bearings on large rollers and cylinders.
- Mining and Construction Equipment: Essential for mounting bearings in crushers, vibrating screens, and heavy machinery gearboxes.
- Marine Propulsion Systems: Used in propeller shaft assemblies for reliable bearing performance.
- Steel Rolling Mills: Provides a robust mounting solution for roller bearings in high-load environments.
- Large Pumps and Compressors: Ensures stable and secure mounting for bearings on main shafts.
Benefits of Using the H 2338 OH Sleeve
- Enhanced Installation Safety: The hydraulic method eliminates the need for heavy hammering or excessive force, creating a safer work environment.
- Prevents Component Damage: Protects both the bearing's precision bore and the shaft surface from scoring or damage during maintenance.
- Improved Operational Reliability: Guarantees a secure and concentric fit, which minimizes vibration and extends bearing life.
- Cost-Effective Assembly: Using adapter sleeves on plain shafts is often more economical than manufacturing complex stepped shafts with shoulders.
- Versatile Positioning: Offers the flexibility to locate the bearing at any point along the shaft, simplifying machine design.
- Simplified Dismounting: Transforms a difficult and time-consuming task into a quick and controlled procedure, reducing machine downtime.
