Product Overview: The H 3996 Adapter Sleeve
The H 3996 is a high-quality adapter sleeve designed to facilitate the mounting of bearings with a tapered bore onto cylindrical shafts. Specifically engineered for a 450mm shaft diameter, this sleeve allows for a secure and precise fit, simplifying installation and ensuring optimal bearing performance. As a key component in our Adapter Sleeves collection and part of the H 3900 Series, the H 3996 is manufactured from robust materials to withstand heavy industrial use. It comes complete with a corresponding lock nut and lock washer, providing a full assembly for locating bearings axially on a shaft.
Adapter sleeves are a cost-effective and versatile solution, eliminating the need for complex and expensive stepped shafts. They allow for wider shaft tolerances and make both mounting and dismounting of bearings a straightforward process. This is particularly beneficial in large-scale machinery where maintenance efficiency is crucial.
Key Features of the H 3996 Adapter Sleeve
- Simplified Bearing Mounting: Enables easy installation of bearings with a tapered bore onto smooth or stepped cylindrical shafts.
- Complete Assembly: Supplied with a high-quality lock nut and lock washer to securely fasten the bearing in place.
- Precision Machined: Guarantees accurate dimensions for a tight, concentric grip on the shaft, minimizing vibration and run-out.
- Slotted Design: Features a slit that allows for effective clamping and a secure fit when the lock nut is tightened.
- High-Strength Material: Constructed from durable steel to ensure reliability and longevity under demanding operational loads.
- Cost-Effective: Negates the need for specially machined shaft shoulders, reducing overall manufacturing costs.
Common Applications
- Industrial Fans and Blowers: Used to mount large bearings on fan shafts, ensuring stable and reliable rotation.
- Conveyor Systems: Ideal for securing bearings on long conveyor shafts and head or tail pulleys.
- Mining and Quarrying Equipment: Provides robust bearing mounting for crushers, screens, and other heavy-duty machinery.
- Pulp and Paper Mills: Essential for mounting bearings in rollers and drums where reliability is critical.
- Large Gearboxes: Facilitates the assembly of bearings on transmission shafts in industrial power systems.
- Agricultural Machinery: Used in large implements like combines and harvesters for reliable shaft and bearing arrangements.
Benefits of Using the H 3996
- Enhanced Installation Efficiency: Drastically reduces the time and complexity involved in mounting and dismounting large bearings.
- Increased Versatility: Allows bearings to be positioned at any point along a cylindrical shaft without the need for shoulders or locating rings.
- Improved Reliability: Creates a secure, 360-degree grip on the shaft, ensuring the bearing operates correctly and reducing the risk of premature failure.
- Reduced Maintenance Costs: The ease of dismounting simplifies bearing replacement, minimizing equipment downtime and labor expenses.
- Accommodates Shaft Tolerances: Can be used with commercial-grade shafts, providing a flexible and economical solution for machinery design.
- Prevents Shaft Damage: Protects the shaft surface from wear and damage that can occur during bearing installation or removal.
