Product Overview: The H 3038 OH Hydraulic Adapter Sleeve
The H 3038 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a 190 mm tapered bore onto 180 mm cylindrical shafts. As a crucial component in our Adapter Sleeves collection, this sleeve simplifies the process of securing large bearings, ensuring a tight and reliable interference fit. The "OH" designation signifies that this sleeve is equipped with oil supply ducts and distribution grooves, allowing for the use of the oil injection method. This hydraulic technique makes both mounting and dismounting significantly easier, faster, and safer by reducing the force required and minimizing the risk of damage to the bearing or shaft.
Part of the robust OH 3000 Series, the H 3038 OH sleeve comes complete with a corresponding lock nut and lock washer. These components work together to securely fasten the bearing in its final position, preventing any axial movement during operation. This sleeve is an indispensable solution for heavy-duty industrial applications where precision, reliability, and ease of maintenance are paramount.
Key Features of the H 3038 OH Sleeve
- Hydraulic Mounting/Dismounting: Integrated oil ducts and grooves facilitate the oil injection method, greatly reducing mounting and dismounting forces.
- Complete Assembly: Supplied as a set with a precision-engineered lock nut (e.g., KM 38) and a secure lock washer (e.g., MB 38).
- Secure Fit: Provides a strong and concentric grip, ensuring precise bearing location on the shaft.
- Shaft Compatibility: Enables the use of bearings with a tapered bore on standard, plain cylindrical shafts without the need for shoulders or special machining.
- High-Quality Material: Manufactured from durable, high-strength steel to withstand high mounting forces and operational loads.
- Slit Design: The sleeve is slit, allowing it to contract and clamp firmly onto the shaft when the lock nut is tightened.
Common Applications
- Heavy Industrial Machinery: Used in large gearboxes, rolling mills, and crushers where bearings are subjected to heavy loads.
- Pulp and Paper Industry: Ideal for mounting bearings on the large rollers found in paper machines.
- Mining and Construction: Essential for equipment such as conveyor belt pulleys, grinding mills, and large excavators.
- Power Generation: Applied in turbines, generators, and large fan assemblies requiring secure bearing arrangements.
- Marine Engineering: Used in propeller shafts and other large-scale marine propulsion systems.
- Material Handling: Suitable for cranes, hoists, and other heavy lifting equipment.
Benefits of Using the H 3038 OH Sleeve
- Simplified Maintenance: The oil injection method dramatically simplifies the process of dismounting large bearings, saving time and labor costs.
- Reduced Risk of Damage: Hydraulic mounting and dismounting prevent scoring or damage to the bearing bore and the shaft seat.
- Enhanced Reliability: Achieves a powerful and uniform interference fit, improving the operational stability and lifespan of the bearing.
- Cost-Effective Shafting: Allows the use of less expensive, commercially available plain shafts, reducing overall machine costs.
- Versatile Positioning: The bearing can be located at any position along a plain shaft, offering greater design flexibility.
- Increased Safety: Eliminates the need for heavy hammering or uncontrolled heating during installation and removal, creating a safer work environment.
