Product Overview: The H 3122 Adapter Sleeve
The H 3122 is a high-quality adapter sleeve designed for securely mounting bearings with a tapered bore onto cylindrical shafts. Specifically engineered for a 100 mm shaft diameter, this component is an essential part of our H 3100 Series within the broader Adapter Sleeves collection. Adapter sleeves are the most commonly used components for locating bearings on a shaft, as they can be used on both plain and stepped shafts. The H 3122 simplifies the mounting process, providing a reliable and precise fit without the need for special shaft machining.
Each H 3122 adapter sleeve assembly is supplied complete with a corresponding lock nut and lock washer, ensuring that the bearing is firmly secured axially. This comprehensive solution prevents loosening in high-vibration environments and facilitates easy dismounting for maintenance or replacement. It is a fundamental component for a wide range of industrial machinery, ensuring optimal performance and longevity.
Key Features of the H 3122
- Complete Mounting Solution: Includes the adapter sleeve, a lock nut (KM 22), and a lock washer (MB 22) for a full assembly.
- Simplified Installation: Allows bearings with a tapered bore to be mounted on smooth or stepped cylindrical shafts with ease.
- Secure Fastening: The lock nut and washer provide strong axial locking, preventing the bearing from coming loose.
- Precision Engineering: Manufactured to tight tolerances to ensure a concentric and secure grip on the shaft.
- Facilitates Dismounting: The design allows for straightforward removal of the bearing from the shaft.
- Versatile Compatibility: Suitable for use with various bearing types, including self-aligning ball bearings and spherical roller bearings.
Common Applications
- Industrial Fans and Blowers: Provides stable and secure mounting for bearings in high-speed rotational equipment.
- Conveyor Belt Pulleys: Used to mount large bearings on conveyor drive and tail pulleys.
- Agricultural Machinery: Essential for mounting bearings in equipment like combines, balers, and tillers.
- Mining and Construction Equipment: Offers a robust solution for heavy-duty applications subject to shock loads and vibration.
- Pulp and Paper Mills: Used in roller assemblies and processing machinery where reliability is critical.
- Gearboxes and Power Transmission: Ensures precise alignment and secure positioning of bearings on shafts.
Benefits of Using the H 3122
- Cost-Effective: Eliminates the need for expensive shaft machining, such as creating a bearing seat or shoulder.
- Enhanced Reliability: Provides a firm, 360-degree grip on the shaft, improving the operational stability of the bearing.
- Reduced Maintenance Time: The straightforward installation and removal process saves valuable time during maintenance cycles.
- Increased Shaft Life: The sleeve protects the shaft surface from damage that can occur during direct bearing mounting or dismounting.
- Accommodates Shaft Tolerances: Can be used on commercial-grade shafting, allowing for wider shaft diameter tolerances compared to press-fit methods.
- Improved Bearing Performance: Ensures correct radial clearance and seating, which is crucial for maximizing bearing service life.
