Product Overview: The AHX 326 Withdrawal Sleeve
The AHX 326 is a precision-engineered withdrawal sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 130mm diameter. As a critical component in our Withdrawal Sleeves collection, it simplifies the process of securing bearings and, more importantly, facilitates easy dismounting for maintenance or replacement. The sleeve is pressed into the bearing bore, which abuts a shaft shoulder or similar fixed component. This assembly is then secured on the shaft using a lock nut. Part of the robust AHX 3200 Series, the AHX 326 ensures a secure and reliable fit for demanding industrial applications.
Key Features of the AHX 326
- Simplified Dismounting: Specifically designed to allow for the easy removal of bearings from their seating without damaging the bearing or the shaft.
- Secure Bearing Location: Provides a firm and reliable method for axially positioning bearings on a cylindrical shaft.
- High-Quality Material: Manufactured from durable, high-strength steel to withstand high mounting forces and operational stresses.
- Precision Machining: Guarantees tight tolerances for a consistent and accurate fit between the bearing, sleeve, and shaft.
- Versatile Compatibility: Designed for use with a wide range of bearings with a 1:12 tapered bore, such as spherical roller and self-aligning ball bearings.
- Cost-Effective Solution: Eliminates the need for specialized machining of the shaft, allowing the use of standard cylindrical shafts.
Common Applications
- Industrial Gearboxes: Used to mount large gears and bearings securely onto shafts, facilitating easier maintenance.
- Conveyor Systems: Ideal for mounting bearings in conveyor belt pulleys and rollers where regular maintenance is required.
- Mining and Construction Equipment: Provides robust bearing mounting in heavy machinery like crushers, screens, and excavators.
- Pulp and Paper Mills: Essential for machinery with long shafts and multiple bearings, such as rollers and presses, where easy dismounting is critical.
- Large Fans and Blowers: Ensures secure mounting of bearings supporting large fan assemblies, simplifying the replacement process.
- Agricultural Machinery: Employed in heavy-duty equipment like combines and balers for reliable bearing performance and serviceability.
Benefits of Using the AHX 326 Sleeve
- Reduced Maintenance Time: The primary advantage is the significant reduction in time and effort required to dismount bearings.
- Prevents Shaft Damage: By providing a smooth surface for the bearing, it protects the shaft from wear and scoring during operation and dismounting.
- Enhanced Operational Reliability: Creates a solid, full-contact fit that minimizes vibration and improves the overall stability of the bearing arrangement.
- Simplified Assembly Design: Allows for more straightforward and less costly machine design by enabling the use of commercially available cylindrical shafts.
- Extended Bearing Life: A proper and secure mounting is crucial for achieving the maximum service life of a bearing.
- Flexible Axial Positioning: The bearing can be accurately positioned at any point on the shaft, offering greater design flexibility.
