Product Overview: The H 3148 Adapter Sleeve
The H 3148 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 240mm diameter. As a critical component in our Adapter Sleeves collection, it provides a simple, reliable, and cost-effective method for securing bearings, allowing for wider shaft tolerances and easy installation. This sleeve is part of the versatile H 3100 Series, which is widely used across numerous industrial applications to ensure a tight fit and prevent slippage between the bearing and the shaft.
Manufactured to precise industry standards, the H 3148 adapter sleeve simplifies the bearing mounting process significantly. It is supplied complete with a corresponding lock nut and lock washer, facilitating both installation and dismounting for maintenance. This design eliminates the need for special shaft machining, making it an essential accessory for a wide range of machinery. Explore our full range of Sleeves to find the perfect solution for your bearing assembly needs.
Key Features of the H 3148 Sleeve
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on plain or stepped cylindrical shafts.
- Secure Fit: When tightened with the lock nut, it provides a strong interference fit, securely locking the bearing in its axial position.
- Precision Machined: Manufactured from high-quality steel with a precision-ground tapered surface for optimal contact and load distribution.
- Split Design: Features a longitudinal slit that allows for easy contraction and a firm grip on the shaft.
- Complete Assembly: Designed to be used with a specific lock nut and lock washer (sold separately) for a complete and secure mounting solution.
- Facilitates Dismounting: Simplifies the process of removing bearings from the shaft during maintenance or replacement.
Common Applications of H 3148
- Conveyor Systems: Used for mounting bearings on head and tail pulley shafts.
- Industrial Fans and Blowers: Secures bearings in large-scale ventilation and air-handling units.
- Mining and Quarrying Equipment: Essential for mounting bearings in crushers, screeners, and grinding mills.
- Agricultural Machinery: Applied in heavy-duty equipment like combines and balers where robust bearing mounting is required.
- Pulp and Paper Mills: Used in roller assemblies and processing machinery.
- Construction Machinery: Supports rotating components in heavy equipment such as excavators and cranes.
- Power Transmission Systems: Provides reliable bearing mounting in gearboxes and large motor shafts.
Benefits of Using the H 3148 Adapter Sleeve
- Cost-Effective: Eliminates the need for expensive, precisely machined shaft shoulders or keyways.
- Increased Versatility: Allows for the use of standard commercial shafts, reducing inventory and manufacturing costs.
- Enhanced Reliability: Provides a concentric and secure grip on the shaft, reducing vibration and improving the operational life of the bearing.
- Ease of Installation: The sleeve can be positioned at any point on a plain shaft, making assembly quick and straightforward.
- Simplified Maintenance: Facilitates easy dismounting of the bearing without causing damage to the shaft or bearing.
- Accommodates Shaft Tolerances: Can be used on shafts with wider commercial tolerances compared to direct-fit bearings.
