Product Overview: The H 3184 OH Hydraulic Adapter Sleeve
The H 3184 OH is a high-performance adapter sleeve designed for mounting bearings with a 420 mm tapered bore onto cylindrical shafts. As a crucial component in our Sleeves and Bearing Accessories range, it provides a simple and reliable method for securing large bearings. This sleeve is part of the OH 3100 Series, which is specifically engineered for hydraulic mounting and dismounting. The 'OH' designation indicates that the sleeve features oil supply ducts and distribution grooves, allowing for oil to be injected between the mating surfaces. This hydraulic method significantly reduces the force required for installation and removal, preventing damage to both the bearing and the shaft.
Manufactured to precise tolerances, the H 3184 OH ensures a secure fit, accurately locating the bearing axially and radially on the shaft. It is supplied as a complete assembly with a corresponding lock nut and lock washer, providing everything needed for a robust mounting solution. This product is ideal for heavy-duty industrial applications where reliability and ease of maintenance are paramount.
Key Features of the H 3184 OH
- Hydraulic Mounting/Dismounting: Equipped with oil ducts and grooves for the oil injection method, simplifying the handling of large bearings.
- Complete Assembly: Supplied with a high-strength lock nut and a secure lock washer for a full mounting solution.
- Precision Taper: The sleeve's outer surface has a precision-ground taper (typically 1:12) to match the bearing's tapered bore, ensuring uniform contact and load distribution.
- Facilitates Use of Standard Shafts: Allows for the use of commercially available plain shafts, eliminating the need for expensive and complex stepped shafts.
- Secure Axial Positioning: Enables the bearing to be firmly positioned anywhere on a smooth shaft, providing flexibility in machine design.
- Reusable Component: Designed for durability, the sleeve can be reused in multiple applications provided it is not damaged during dismounting.
Common Applications
- Mining and Quarrying Equipment: Used in crushers, conveyor pulleys, and large gearboxes where bearings are subjected to heavy loads and harsh conditions.
- Pulp and Paper Mills: Essential for mounting bearings on the rolls of paper machines, where easy dismounting for maintenance is critical.
- Steel and Metal Rolling Mills: Applied in roll-neck bearings and continuous casting machines that require robust and reliable bearing arrangements.
- Large Industrial Fans and Blowers: Secures bearings on large fan shafts, with the hydraulic feature aiding in field service and maintenance.
- Marine Propulsion Systems: Used for mounting propeller shaft bearings and in other heavy marine machinery.
- Power Generation: Found in turbines, generators, and large gear drives where precise and secure bearing location is vital for operational efficiency.
Benefits of Using the H 3184 OH
- Simplified Installation: The hydraulic method drastically reduces the mounting force required, making the installation of large bearings faster and safer.
- Damage-Free Dismounting: Oil injection allows the sleeve to be removed without scoring or damaging the shaft or bearing bore, preserving component integrity.
- Improved Reliability: Provides a rigid and concentric grip on the shaft, enhancing the operational stability and performance of the bearing.
- Reduced Maintenance Time: The ease of hydraulic mounting and dismounting significantly cuts down on downtime during maintenance and replacement cycles.
- Cost-Effective Solution: Eliminates the need for special shaft machining (like shoulders or keyways), reducing overall manufacturing costs.
- Versatile Application: Allows bearings to be mounted on shafts of various diameters within a tolerance range, offering design and assembly flexibility.
