Product Overview: The AHX 309 Withdrawal Sleeve
The AHX 309 is a high-precision withdrawal sleeve, an essential component for mounting bearings with a tapered bore onto cylindrical stepped shafts. Specifically designed for a 40mm shaft diameter, this sleeve facilitates the easy dismounting of bearings. As part of our extensive Withdrawal Sleeves collection and the AHX 300 Series, the AHX 309 ensures a secure and accurate fit, simplifying maintenance and assembly processes in a wide range of industrial machinery.
Withdrawal sleeves are pulled into the bearing bore, which is pressed against a shaft shoulder or similar fixed component. This method provides a reliable interference fit and is particularly advantageous in applications where bearings need to be removed periodically for inspection or replacement, as it prevents damage to both the shaft and the bearing during dismounting.
Key Features of the AHX 309 Sleeve
- Simplified Dismounting: Designed specifically to make the removal of bearings from their seating straightforward and damage-free.
- Precision Machining: Manufactured to tight tolerances to ensure a perfect fit and concentric running, which is crucial for bearing performance and longevity.
- Slotted Design: Features a longitudinal slot that allows for slight compression, ensuring a secure grip on the shaft once the bearing is mounted.
- High-Strength Material: Constructed from durable, high-quality steel to withstand the forces involved in mounting and dismounting operations.
- Standardized Dimensions: Conforms to industry standards, making it interchangeable with other AHX 309 sleeves.
- Corrosion Resistance: Often treated with a protective coating to resist rust and corrosion in various operating environments.
Common Applications
- Industrial Gearboxes: Used to mount gears and bearings securely, while allowing for easier maintenance and repair.
- Conveyor Belt Pulleys: Facilitates the mounting of large bearings on conveyor drive shafts, which often require periodic service.
- Large Fans and Blowers: Ensures robust mounting for bearings in high-vibration environments like industrial ventilation systems.
- Mining and Construction Equipment: Ideal for heavy-duty machinery where components are subjected to extreme loads and require frequent maintenance.
- Pulp and Paper Mills: Used in roller assemblies and processing machinery where reliable operation and easy serviceability are critical.
- Agricultural Machinery: Applied in equipment like combines and harvesters for mounting bearings on transmission and axle shafts.
Benefits of Using the AHX 309
- Reduced Maintenance Time: The primary benefit is the significant reduction in time and effort required to dismount bearings.
- Prevents Shaft Damage: Eliminates the need for hammers or pullers that can score or damage the shaft surface during bearing removal.
- Cost-Effective Solution: By simplifying maintenance and preventing component damage, it helps lower the total cost of ownership.
- Improved Reliability: Provides a secure and rigid mounting, which contributes to the overall reliability and performance of the rotating assembly.
- Extended Bearing Life: A proper fit and easy, damage-free dismounting process help to maximize the service life of the bearing.
- Versatile Use: Can be used with various bearing types that have a tapered bore, including self-aligning ball bearings and spherical roller bearings.
