Product Overview: The H 3188 Adapter Sleeve
The H 3188 Adapter Sleeve is a precision-engineered component designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 440mm diameter. As a key part of our H 3100 Series, this sleeve simplifies the installation process, providing a secure and reliable fit without the need for complex shaft machining. It is an essential component within our extensive range of Adapter Sleeves and Bearing Accessories.
Adapter sleeves are the most commonly used components for locating bearings on a shaft, as they can be used on plain or stepped shafts. They are easy to install and require no additional location on the shaft. The H 3188, complete with a lock nut and lock washer, ensures that the bearing is firmly positioned axially, preventing movement and ensuring optimal performance in demanding industrial applications.
Key Features of the H 3188
- Simplified Mounting: Allows for easy installation of bearings with a tapered bore onto smooth or stepped cylindrical shafts.
- Secure Fastening: Comes as a complete assembly with a suitable lock nut and lock washer to firmly secure the bearing in place.
- Tapered Design: Features a tapered outer surface that matches the bearing's inner ring, ensuring a tight interference fit when the lock nut is tightened.
- Slit Construction: The sleeve is slit, which allows it to contract and grip the shaft securely during installation.
- High-Quality Material: Manufactured from durable steel to withstand high mounting forces and operational stresses, ensuring long service life.
- Versatile Application: Enables the use of standard commercial shafts, reducing the need for expensive custom machining.
Common Applications
- Industrial Fans and Blowers: Used to mount large bearings on fan shafts, ensuring stability and reliability.
- Conveyor Belt Pulleys: Provides a secure mounting solution for bearings in pulley systems, which are critical for material handling.
- Mining and Quarrying Equipment: Essential for mounting bearings in crushers, vibrating screens, and other heavy-duty machinery.
- Pulp and Paper Mills: Used in rollers and processing equipment where reliable bearing performance is crucial.
- Large Gearboxes and Transmissions: Facilitates the mounting of bearings on transmission shafts in large industrial power systems.
- Agricultural Machinery: Applied in heavy equipment like combines and balers for secure bearing placement on shafts.
Benefits of Using the H 3188 Adapter Sleeve
- Cost-Effective Installation: Eliminates the need for special shaft shoulders, keyways, or threads, lowering manufacturing costs.
- Enhanced Reliability: Provides a strong, concentric grip on the shaft, ensuring the bearing operates smoothly and reducing vibration.
- Easy Maintenance: Simplifies the process of dismounting bearings for inspection or replacement, minimizing downtime.
- Improved Bearing Life: A secure and correct fit prevents inner ring rotation and shaft damage, extending the operational life of the bearing.
- Positional Flexibility: Allows the bearing to be positioned at any point along a smooth shaft, offering design flexibility.
- Accommodates Shaft Tolerances: Can be used with commercial-grade shafts that have wider diameter tolerances than those required for direct bearing mounting.
