Product Overview: H 2348 Adapter Sleeve
The H 2348 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 240mm diameter. As a crucial component in our Bearing Accessories range, this sleeve is part of the versatile H 2300 Series within the broader H Series of Adapter Sleeves. It provides a simple, reliable, and cost-effective method for securing bearings, ensuring a tight fit and simplifying the overall assembly and disassembly process. This complete assembly includes the corresponding lock nut and lock washer, providing everything needed for a secure installation.
Adapter sleeves are essential in a wide variety of industrial applications, particularly where precise shaft machining to bearing tolerance is not feasible. The H 2348 allows for the use of commercial-grade shafting, significantly reducing manufacturing costs while ensuring the bearing is correctly located and secured against axial movement.
Key Features of the H 2348
- Complete Mounting Solution: Supplied as a complete set with a precision-engineered sleeve, a high-strength lock nut, and a secure lock washer.
- Facilitates Easy Mounting: Simplifies the process of mounting tapered bore bearings onto standard cylindrical shafts without the need for shoulders or special machining.
- Secure and Reliable Fit: The tapered design, when tightened with the lock nut, provides a strong frictional lock between the bearing and the shaft.
- Cost-Effective: Allows for wider shaft tolerances, reducing the need for expensive, high-precision shaft grinding.
- Slotted Design: The sleeve is slotted to allow for contraction, ensuring a tight grip on the shaft along its entire circumference.
- Simplified Dismounting: Makes bearing removal straightforward, reducing downtime and maintenance complexity.
Common Applications
- Heavy Industrial Fans and Blowers: Used to mount large bearings on fan shafts, ensuring stability and longevity in high-speed applications.
- Conveyor Belt Pulleys: Provides a secure mounting for pulley bearings, which are subject to heavy loads and constant rotation.
- Mining and Quarrying Equipment: Ideal for crushers, screeners, and conveyors where robust and reliable bearing mounting is critical.
- Pulp and Paper Machinery: Secures bearings on rollers and drums in demanding, high-moisture environments.
- Agricultural Machinery: Employed in large equipment like combines and harvesters for mounting bearings on main shafts.
- Steel Mill Equipment: Used in rolling mills and processing lines to handle extreme loads and high temperatures.
- Large Pumps and Gearboxes: Ensures precise and secure location of bearings on drive shafts and gear assemblies.
Benefits of Using the H 2348 Adapter Sleeve
- Enhanced Operational Reliability: Guarantees a secure and concentric fit, minimizing vibration and improving the performance of rotating equipment.
- Reduced Maintenance Time: The straightforward installation and removal process significantly cuts down on maintenance hours and labor costs.
- Increased Bearing Service Life: Proper mounting with an adapter sleeve prevents inner ring rotation on the shaft, a common cause of premature bearing failure.
- Versatility in Design: Allows bearings to be located at any position on a smooth shaft, offering greater flexibility in machine design.
- Protection for Shafts: Prevents damage to the shaft surface during bearing mounting and dismounting operations.
