Product Overview: The H 3072 Adapter Sleeve
The H 3072 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 340mm diameter. As a crucial component in our Adapter Sleeves collection and part of the metric H 3000 Series, this sleeve provides a simple, reliable, and cost-effective method for securing bearings. It allows for the use of standard commercial shafts, eliminating the need for special machining. The sleeve's split design, combined with a lock nut and lock washer, ensures a tight, concentric fit, facilitating both easy installation and dismounting for maintenance.
Adapter sleeves are essential for a wide range of industrial machinery, enabling bearings such as Spherical Roller Bearings and self-aligning ball bearings to be securely located on smooth or stepped shafts. The H 3072 is manufactured to precise tolerances to guarantee dependable performance in demanding operational environments.
Key Features of the H 3072 Adapter Sleeve
- Simplified Bearing Mounting: Allows for easy and quick installation of tapered bore bearings on cylindrical shafts.
- Secure Fit: Ensures a strong, concentric grip on the shaft when tightened with the corresponding lock nut, preventing slippage.
- Facilitates Dismounting: The design allows for straightforward removal of the bearing for maintenance or replacement.
- Use with Commercial Shafts: Eliminates the need for expensive and time-consuming shaft machining, shoulders, or special retention methods.
- Complete Assembly: Typically supplied as a complete set with a precision-engineered lock nut and a secure lock washer.
- Metric Standard: Designed to internationally recognized metric standards for broad compatibility.
Common Applications
- Heavy-Duty Conveyor Systems: Used to mount bearings on long conveyor drive shafts where precise shoulders are impractical.
- Industrial Fans and Blowers: Provides a secure mounting for fan shaft bearings, ensuring stable and vibration-free operation.
- Mining and Quarrying Equipment: Essential for mounting bearings in crushers, vibrating screens, and other machinery subject to heavy loads and harsh conditions.
- Pulp and Paper Mills: Widely used in rollers, presses, and processing equipment where reliability is critical.
- Agricultural Machinery: Applied in large equipment like combines and harvesters for mounting bearings on transmission shafts.
- Large-Scale Gearboxes: Enables secure positioning of bearings on input and output shafts.
- Steel Mill Equipment: Used in rolling mills and continuous casting machines for robust bearing mounting solutions.
Benefits of Using the H 3072 Adapter Sleeve
- Cost-Effective: Reduces overall assembly costs by simplifying shaft design and eliminating the need for precision machining.
- Increased Versatility: Allows bearings to be located at any position on a smooth shaft, offering greater design flexibility.
- Improved Reliability: Creates a rigid and reliable assembly that enhances the operational life of the bearing and machinery.
- Reduced Downtime: The ease of mounting and dismounting simplifies maintenance procedures, minimizing equipment downtime.
- Compensates for Shaft Tolerances: Can accommodate slightly wider tolerances on the shaft diameter compared to press-fit methods.
- Enhanced Operational Safety: The combination of the sleeve, lock nut, and lock washer provides a secure mechanical lock, preventing loosening in high-vibration applications.
