Product Overview: The H 3084 OH Hydraulic Adapter Sleeve
The H 3084 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a 420 mm tapered bore onto a 400 mm cylindrical shaft. As a key component in our Adapter Sleeves collection, this product simplifies the installation and removal of large bearings, ensuring a secure and precise fit. The "OH" designation signifies that it is part of the OH Series, which includes features for oil injection (hydraulic method), and is supplied as a complete set with a corresponding lock nut and lock washer.
This sleeve is engineered to facilitate the mounting process, particularly in heavy-duty applications where conventional methods would be difficult and time-consuming. The hydraulic capability allows for effortless positioning and dismounting, minimizing the risk of damage to both the bearing and the shaft. Manufactured to exacting standards, the H 3084 OH provides a reliable solution for securing bearings in demanding industrial environments.
Key Features of the H 3084 OH Sleeve
- Complete Mounting Solution: Supplied with a high-strength lock nut and a secure lock washer for a full assembly.
- Hydraulic Mounting/Dismounting: Equipped with oil supply ducts and distribution grooves for easy and safe oil injection mounting and removal.
- Precise Bearing Location: Enables bearings to be accurately positioned on the shaft and securely fixed in place.
- Accommodates Shaft Tolerances: Can be used on plain shafts, allowing for wider shaft diameter tolerances compared to direct-mounting methods.
- Durable Construction: Made from high-quality steel to withstand high mounting forces and operational loads, ensuring long-term reliability.
- Split Sleeve Design: The sleeve is slotted, allowing it to clamp firmly onto the shaft when the lock nut is tightened.
Common Applications
- Mining and Construction: Used in large crushers, grinding mills, and heavy earth-moving equipment where robust bearing arrangements are critical.
- Pulp and Paper Industry: Ideal for mounting bearings on the large rolls found in paper machines and processing equipment.
- Steel and Metal Mills: Essential for securing bearings in rolling mills, continuous casters, and other high-load machinery.
- Large Fans and Blowers: Provides a secure mounting solution for bearings in industrial ventilation and air handling systems.
- Conveyor Systems: Widely used for mounting bearings on large drive pulleys and tensioning drums in heavy-duty conveyors.
- Marine and Offshore: Applied in ship propulsion systems, rudder stocks, and deck machinery requiring reliable bearing fixation.
Benefits of Using the H 3084 OH
- Simplified Installation: The hydraulic method significantly reduces the force and time required to mount large bearings.
- Damage-Free Dismounting: Oil injection allows bearings to be removed from the shaft without scoring or damaging the components.
- Enhanced Operational Safety: Ensures a tight, reliable interference fit, preventing the bearing's inner ring from spinning on the shaft.
- Reduced Maintenance Downtime: The speed and ease of hydraulic mounting and dismounting minimize the time machinery is out of service.
- Extended Component Life: Proper and secure mounting reduces vibration and fretting corrosion, extending the service life of both the bearing and the shaft.
- Cost-Effective: Allows for the use of less precisely machined commercial shafts, reducing overall manufacturing costs.
