Product Overview: The AHX 317 Withdrawal Sleeve
The AHX 317 is a precision-engineered withdrawal sleeve designed to facilitate the easy dismounting of bearings with a tapered bore from a cylindrical shaft seat. This sleeve is a critical component for an 80mm diameter shaft and is used with bearings that have a 1:12 taper, such as those in the 1300, 2300, 22200, and 23200 series. As a key part of our Sleeves and Withdrawal Sleeves collections, the AHX 317 from the AHX 300 Series simplifies maintenance by allowing bearings to be removed quickly without causing damage to the bearing or the shaft.
Withdrawal sleeves are pulled into the bearing bore by tightening a lock nut against the bearing's inner ring, which presses the bearing up the sleeve's taper until the required reduction in radial internal clearance is achieved. The sleeve's slit design ensures a secure, friction-based grip on the shaft, providing a reliable and precise mounting solution. This method is essential in heavy-duty industrial applications where secure bearing location and straightforward maintenance are paramount.
Key Features of the AHX 317
- Simplified Bearing Dismounting: Specifically designed to make the removal of tapered bore bearings from cylindrical shafts quick and easy.
- Prevents Shaft Damage: Allows for bearing removal without the need for excessive force or specialized pullers that could damage the shaft surface.
- Precision Fit: Machined to tight tolerances to ensure a secure and accurate fit for both the 80mm shaft and the corresponding bearing.
- High-Quality Material: Constructed from durable steel to withstand the high pressures involved in mounting and dismounting operations.
- Cost-Effective Mounting: Enables the use of standard cylindrical shafts, which are more economical than stepped shafts, for mounting bearings with a tapered bore.
- Enhanced Operational Security: The sleeve's taper provides a solid, reliable fit, securely locating the bearing axially on the shaft.
Common Applications
- Industrial Gearboxes: Used for mounting bearings on transmission shafts, allowing for easier maintenance and repair.
- Conveyor Systems: Ideal for securing bearings on long conveyor shafts where periodic replacement is necessary.
- Large Fans and Blowers: Facilitates the maintenance of bearings in air handling units and industrial ventilation systems.
- Pumps and Compressors: Ensures bearings can be easily dismounted from pump shafts without requiring a complete teardown.
- Mining and Quarrying Equipment: Essential for heavy-duty machinery like crushers and screening plants where components undergo frequent maintenance.
- Pulp and Paper Mills: Used in roller assemblies and other rotating equipment where bearing replacement must be efficient to minimize downtime.
Benefits of Using the AHX 317
- Reduced Downtime: The primary benefit is the significant reduction in time required for bearing inspection and replacement.
- Extended Component Life: By preventing damage during dismounting, it helps prolong the service life of both the shaft and the bearing.
- Lower Maintenance Costs: Simplifies the maintenance process, reducing labor costs and the need for expensive, specialized tools.
- Improved Design Flexibility: Allows engineers to use bearings with a tapered bore on simple cylindrical shafts, simplifying overall machine design.
- Reliable Performance: Provides a robust and dependable method for securing bearings, ensuring stable operation even under heavy loads and vibration.
