Product Overview: The HE 310 Adapter Sleeve
The HE 310 Adapter Sleeve is a crucial component used for securely mounting bearings with a tapered bore onto a cylindrical shaft with a 45mm diameter. As part of our extensive range of Adapter Sleeves, this high-tensile strength sleeve simplifies installation and ensures a tight, reliable fit between the shaft and the bearing's inner ring. The HE 310 is part of the HE 300 Series and is designed for use in heavy-duty applications where significant loads are present.
This adapter sleeve assembly includes the sleeve itself, a KM 10 lock nut, and an MB 10 lock washer. The split sleeve design allows for easy installation and removal without requiring a shoulder or stop on the shaft, making it a cost-effective and versatile mounting solution. By using an adapter sleeve, standard shafts with wider tolerances can be used, reducing overall manufacturing costs.

Key Features of the HE 310 Sleeve
- Shaft Compatibility: Designed for mounting bearings onto 45mm cylindrical shafts.
- Complete Assembly: Typically used with a KM 10 lock nut and MB 10 lock washer to secure the bearing in place.
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on plain or stepped shafts, eliminating the need for precise shaft shoulders.
- High-Strength Material: Manufactured from high-quality steel to withstand heavy radial loads and ensure long-term durability.
- Split Design: The longitudinal slit in the sleeve facilitates easy installation and provides a strong, concentric grip on the shaft.
- Cost-Effective: Enables the use of commercial-grade shafts with wider tolerances, reducing machining costs and complexity.
Common Applications
- Industrial Fans and Blowers: Provides a secure mounting for fan shaft bearings, ensuring stable and vibration-free operation.
- Conveyor Belt Pulleys: Used to mount bearings in pulley systems, allowing for easy assembly and maintenance.
- Agricultural Machinery: Ideal for equipment such as combines and balers where components need to be robust and easily serviceable.
- Mining and Construction Equipment: Supports bearings in crushers, screens, and other heavy-duty machinery operating in harsh environments.
- Pumps and Gearboxes: Ensures precise alignment and secure fitting of bearings on drive shafts.
- Paper and Textile Mills: Used in roller applications where reliable bearing mounting is essential for continuous production.
Benefits of Using the HE 310 Adapter Sleeve
- Enhanced Reliability: Provides a rigid and secure fit, preventing fretting corrosion and extending the service life of both the bearing and the shaft.
- Easy Installation and Dismounting: The sleeve can be easily pushed into the bearing bore and tightened with the lock nut, simplifying the assembly process.
- Improved Bearing Performance: Ensures correct radial clearance and concentricity, which is critical for optimal bearing operation and longevity.
- Versatility: Allows a single bearing size to be used on shafts of different diameters by simply changing the adapter sleeve.
- Reduced Maintenance Time: Simplifies the process of replacing bearings, minimizing machinery downtime.
- Accommodates Shaft Tolerances: Can be used on shafts that are not machined to the tight tolerances required for interference fits.
