Product Overview: H 3084 Adapter Sleeve
The H 3084 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 420mm diameter. As a crucial component in our Adapter Sleeves collection, it is part of the extensive H 3000 Series. Adapter sleeves are the most commonly used components for locating bearings, as they can be used on plain shafts or stepped shafts. They simplify the mounting process, requiring no additional location on the shaft, and facilitate easy dismounting for maintenance.
This sleeve assembly, which includes a precision-engineered sleeve, a corresponding lock nut, and a lock washer, provides a secure and reliable fit. By tightening the lock nut, the bearing is driven up the tapered sleeve, creating a strong interference fit on the shaft. This ensures concentric positioning and stable operation, even in demanding industrial environments.
Key Features of the H 3084 Sleeve
- Simplified Mounting: Enables easy, secure, and precise mounting of bearings with a tapered bore onto standard cylindrical shafts.
- Tapered Design: Features a 1:12 taper to create a strong interference fit between the bearing and the shaft.
- Complete Assembly: Supplied with a high-quality lock nut and lock washer to securely fasten the bearing in place.
- Slit Construction: The sleeve is slit, allowing it to contract and clamp firmly onto the shaft when the lock nut is tightened.
- High-Strength Material: Manufactured from durable steel to withstand high mounting forces and operational loads.
- Facilitates Dismounting: Designed for straightforward removal, making bearing inspection, maintenance, and replacement more efficient.
Common Applications
- Heavy Industrial Fans and Blowers: Used to mount large rotor bearings securely onto drive shafts.
- Mining and Quarrying Equipment: Essential for mounting bearings in conveyors, crushers, and screening machinery.
- Pulp and Paper Mills: Provides reliable mounting for rollers in paper processing machines.
- Steel Manufacturing: Applied in rolling mills and other heavy-duty equipment where robust bearing arrangements are critical.
- Large-Scale Power Transmission: Used in gearboxes, plummer block housings, and other systems requiring secure shaft-bearing connections.
- Cement Production: Suitable for kilns, grinding mills, and other machinery operating under heavy loads and harsh conditions.
Benefits of Using the H 3084
- Cost-Effective Shafting: Allows for the use of commercially available plain shafts, reducing the need for expensive, precisely machined shaft shoulders.
- Enhanced Reliability: Provides a secure, 360-degree grip that prevents fretting corrosion and ensures the bearing is properly located.
- Improved Bearing Life: Correct mounting with an adapter sleeve ensures proper bearing alignment and clearance, extending its operational lifespan.
- Easy Installation and Adjustment: The axial position of the bearing on the shaft can be easily adjusted during installation.
- Reduced Maintenance Time: The design simplifies both the mounting and dismounting processes, minimizing machinery downtime.
- Versatile Application: Can be used on both plain and stepped shafts, offering flexibility in machine design and assembly.
