Product Overview: The AHX 3122 Withdrawal Sleeve
The AHX 3122 is a high-quality withdrawal sleeve designed for dismounting bearings with a tapered bore from a cylindrical shaft. Specifically engineered for a 100mm shaft diameter, this sleeve is an essential component in our Bearing Accessories range. As part of the AHX 3100 Series, it provides a simple and effective method for securing and later removing bearings, preventing damage to both the bearing and the shaft during maintenance. Its design incorporates a slit and an external thread for use with a lock nut, ensuring a tight and reliable fit.
Withdrawal sleeves, like the AHX 3122, are crucial for applications where bearings need to be periodically replaced. By pressing the sleeve into the bearing bore, which is mounted against a shaft shoulder, the bearing can be easily removed by tightening a lock nut on the sleeve's thread. Explore our complete collection of Withdrawal Sleeves to find the precise solution for your industrial machinery needs.
Key Features of the AHX 3122
- Simplified Bearing Dismounting: Specifically designed to push the bearing off its tapered seat, making removal quick and easy.
- Precise Manufacturing: Machined to strict tolerances to ensure a perfect fit on 100mm cylindrical shafts and corresponding bearings.
- Durable Construction: Made from high-grade steel to withstand the forces of mounting and dismounting, ensuring a long service life.
- Slotted Design: Features a full-length slit that allows the sleeve to compress slightly for a secure grip on the shaft.
- Cost-Effective Assembly: Allows the use of bearings with a tapered bore on less expensive, straight cylindrical shafts, eliminating the need for a stepped shaft.
- Standardized Dimensions: Conforms to industry standards, ensuring interchangeability and compatibility with various bearing brands.
Common Applications
- Industrial Fans and Blowers: Used in large ventilation systems where easy maintenance of rotor bearings is critical.
- Conveyor Systems: Facilitates the replacement of bearings in conveyor belt pulleys and rollers, minimizing operational downtime.
- Mining and Quarrying Equipment: Essential for machinery such as crushers, vibrating screens, and mills that operate under heavy loads.
- Pulp and Paper Machines: Applied in rollers and cylinders where bearings require periodic servicing.
- Large Pumps and Compressors: Ensures secure mounting and straightforward dismounting of bearings on main shafts.
- Agricultural Machinery: Used in heavy-duty equipment like combines and balers for reliable performance and field serviceability.
- Industrial Gearboxes: Provides a robust solution for mounting gears and bearings on transmission shafts.
Benefits of Using the AHX 3122 Sleeve
- Reduced Maintenance Time: Significantly speeds up the process of bearing removal and replacement.
- Prevents Component Damage: Protects the bearing and the shaft from damage that can occur with improper dismounting techniques.
- Enhanced Reliability: Provides a secure and concentric fit, reducing vibration and improving the overall stability of the bearing assembly.
- Lower Shaft Costs: By enabling the use of straight shafts instead of stepped ones, it helps reduce manufacturing complexity and cost.
- Increased Equipment Uptime: The ease and speed of maintenance lead to less downtime for critical machinery.
- Versatile Solution: Allows for a standardized approach to mounting various types of roller bearings with tapered bores.
