Product Overview: The HE 313 Adapter Sleeve
The HE 313 is a precision-engineered adapter sleeve designed for mounting bearings with a 65mm tapered bore onto a 60mm cylindrical shaft. As a key component in our Bearing Accessories lineup, this sleeve simplifies the installation process, providing a secure and reliable fit without the need for complex shaft machining. Part of the robust HE Series, the HE 313 ensures that bearings can be accurately positioned and easily dismounted for maintenance or replacement.
Adapter sleeves are a cost-effective and versatile solution used across numerous industries. They allow for the use of standard commercial shafting, which can have wider tolerances, saving both time and manufacturing costs. When tightened, the sleeve is compressed onto the shaft, creating a strong interference fit that firmly holds the bearing in its designated axial position. This component is typically used in conjunction with a corresponding lock nut and lock washer to secure the assembly.
Key Features of the HE 313 Adapter Sleeve
- Simplified Bearing Mounting: Enables easy installation of bearings with a tapered bore onto straight cylindrical shafts.
- Secure Fit: Provides a strong, reliable interference fit when the lock nut is tightened, preventing axial movement.
- Compensates for Shaft Tolerances: Allows for the use of commercial-grade shafts with slightly wider diameter tolerances.
- Facilitates Dismounting: The design simplifies the removal of bearings for maintenance or replacement, reducing downtime.
- Precision Machined: Manufactured with a high degree of accuracy, including a precision-ground external taper to match the bearing bore.
- Durable Construction: Made from high-quality steel to withstand high mounting forces and operational stresses.
Common Applications
- Conveyor Systems: Used to mount bearings on long conveyor shafts where stepped machining is impractical.
- Industrial Fans and Blowers: Provides a secure mounting solution for bearings in large fan assemblies.
- Agricultural Machinery: Ideal for equipment such as combines and balers where robust and serviceable bearing arrangements are required.
- Pumps and Compressors: Ensures precise and secure locating of bearings on pump shafts.
- Mining and Construction Equipment: Withstands heavy loads and harsh operating conditions in crushers, screens, and haul trucks.
- Pulp and Paper Mills: Commonly used in paper machine rolls and other rotating equipment.
Benefits of Using the HE 313 Sleeve
- Cost-Effective: Eliminates the need for expensive stepped shafts, reducing overall design and manufacturing costs.
- Reduced Installation Time: The straightforward mounting process is faster than other methods like heating or pressing.
- Enhanced Versatility: Allows bearings to be positioned at any point along a straight shaft, offering design flexibility.
- Improved Serviceability: Bearings can be easily dismounted and replaced, simplifying maintenance procedures.
- Shaft Protection: The sleeve protects the shaft surface from damage during bearing installation and removal.
- Reliable Performance: Creates a dependable, 360-degree contact between the bearing and shaft, ensuring stable operation.
