Product Overview: The H 3140 OH Hydraulic Adapter Sleeve
The H 3140 OH is a high-performance adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 180mm diameter. As a key component in our Adapter Sleeves range, it is part of the robust H 3100 Series. The 'OH' designation signifies that this sleeve is equipped with oil supply ducts and distribution grooves, enabling the use of the hydraulic method for mounting and dismounting large bearings. This feature greatly simplifies the installation process, reduces the risk of damaging the bearing or shaft, and ensures a secure, precise fit.
Supplied complete with a lock nut and a locking washer, the H 3140 OH provides a full solution for securely positioning bearings such as the 23140 spherical roller bearing. It is an indispensable component in heavy-duty industrial applications where reliability and ease of maintenance are paramount. Explore our comprehensive collection of OH Series hydraulic sleeves to find the perfect solution for your machinery.
Key Features of the H 3140 OH
- Hydraulic Mounting/Dismounting: Features integrated oil ducts and grooves to facilitate easy, safe, and quick installation and removal using the oil injection method.
- Secure Bearing Location: Allows bearings with a tapered bore to be firmly positioned on a cylindrical shaft seat.
- Complete Assembly: Comes as a set with a corresponding high-precision lock nut and locking washer for a secure fit.
- Versatile Application: Enables the use of standard shafts, eliminating the need for special machining or shouldered shafts, which can be more expensive.
- Precision Engineering: Manufactured from high-strength steel to exacting standards, ensuring dimensional accuracy and reliable performance under heavy loads.
- Slit Design: The sleeve is slit, allowing it to clamp down securely on the shaft when the lock nut is tightened.
Common Applications
- Mining and Quarrying: Used in crushers, conveyor systems, and heavy excavators where large bearings are subjected to extreme conditions.
- Pulp and Paper Industry: Essential for mounting bearings on the large rollers found in paper machines.
- Steel and Metal Mills: Applied in rolling mills, continuous casters, and other heavy machinery requiring robust bearing arrangements.
- Large Industrial Fans and Blowers: Ensures secure mounting of bearings in large-scale ventilation and air-handling systems.
- Marine and Offshore: Utilized in propeller shafts, rudder systems, and deck machinery where reliability is critical.
- Cement and Construction: Deployed in grinding mills, kilns, and large gearboxes.
Benefits of Using the H 3140 OH Sleeve
- Reduced Maintenance Time: The hydraulic method significantly speeds up the mounting and dismounting process compared to traditional mechanical methods.
- Prevents Damage: Minimizes the risk of scoring or damaging the bearing bore and shaft surface during installation and removal.
- Enhanced Reliability: Provides a strong, uniform grip on the shaft, ensuring the bearing operates correctly and reducing the risk of fretting corrosion.
- Cost-Effective: Allows for the use of commercially available shafts with wider tolerances, reducing overall manufacturing and assembly costs.
- Improved Operational Safety: The controlled nature of hydraulic mounting is safer for technicians than using heavy hammers and brute force.
- Precise Adjustment: Enables accurate axial positioning of the bearing on the shaft, which is crucial for optimal performance and longevity.
