Product Overview: H 3964 Adapter Sleeve
The H 3964 is a precision-engineered adapter sleeve from our H 3900 Series, designed for mounting bearings with a tapered bore onto cylindrical shafts. With a shaft diameter of 320 mm, this sleeve provides a secure and reliable method for locating bearings, simplifying both installation and dismounting procedures. It is a critical component in our range of Adapter Sleeves, essential for creating robust and serviceable bearing arrangements in heavy-duty industrial machinery.
Adapter sleeves like the H 3964 eliminate the need for specialized shaft machining, such as shoulders or lock nut threads, allowing for the use of standard commercial shafts. This component works by being pressed into the bearing's tapered bore, which clamps it firmly onto the shaft. The assembly is then secured using an appropriate lock nut and lock washer. This method ensures a tight, concentric fit, reducing vibration and extending the operational life of the entire assembly.
Key Features of the H 3964 Adapter Sleeve
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on plain or stepped cylindrical shafts easily.
- Precision Machined: Manufactured with tight tolerances to ensure accurate and concentric shaft alignment.
- Slit Design: Features a longitudinal slit that allows for effective clamping onto the shaft when tightened.
- High-Strength Material: Constructed from durable steel to withstand high mounting forces and operational loads.
- Complete System: Designed to be used with a corresponding lock nut and lock washer for a secure and complete fastening solution.
- Versatile Positioning: Enables the bearing to be positioned at any point along a straight shaft without the need for shoulders.
Common Applications
- Large Industrial Fans and Blowers: Used to mount large bearings on fan shafts, ensuring stability and ease of maintenance.
- Conveyor Systems: Essential for securing bearings on the drive and tail pulleys of heavy-duty conveyors.
- Mining and Construction Equipment: Found in crushers, grinding mills, and shaker screens where robust bearing arrangements are critical.
- Pulp and Paper Machinery: Utilized in rollers and drums that require precise and secure bearing mounting.
- Steel Mills: Applied in rolling mills and other heavy machinery where bearings are subjected to extreme loads.
- Large Gearboxes: Facilitates the mounting of bearings on transmission shafts, simplifying assembly and repair.
- Marine Propulsion Systems: Secures bearings on propeller shafts and other critical rotating equipment.
Benefits of Using the H 3964
- Cost-Effective Shafts: Reduces manufacturing costs by allowing the use of less complex, straight cylindrical shafts.
- Enhanced Reliability: Provides a secure, 360-degree grip on the shaft, ensuring the bearing is firmly located and reducing the risk of fretting corrosion.
- Ease of Maintenance: Simplifies the dismounting process, allowing for quicker bearing inspection, maintenance, or replacement.
- Increased Bearing Life: A proper, secure fit minimizes vibration and stress, contributing to a longer service life for the bearing.
- Flexible Assembly: Offers the flexibility to position bearings precisely where needed along the shaft length.
- Shaft Protection: Protects the shaft surface from damage during installation and removal, preserving its integrity.
