Product Overview: The AHX 312 Withdrawal Sleeve
The AHX 312 is a high-quality withdrawal sleeve, an essential component from our AHX Series of Withdrawal Sleeves, designed for mounting bearings with a tapered bore onto a 60 mm cylindrical shaft. This sleeve simplifies the entire bearing lifecycle, from initial installation to subsequent dismounting for maintenance or replacement. Its primary function is to facilitate the easy removal (withdrawal) of the bearing from its seating, which is achieved by applying force to the sleeve via a lock nut.
Manufactured to precise industry standards, the AHX 312 ensures a secure and concentric fit, which is critical for the optimal performance and longevity of the bearing assembly. As a key part of our Bearing Accessories range, these sleeves are indispensable in heavy-duty machinery where reliability and ease of maintenance are paramount. They are commonly used with spherical roller bearings, such as the 22212, and self-aligning ball bearings.
Key Features of the AHX 312 Sleeve
- Simplified Dismounting: Specifically designed to make the removal of bearings from their shaft seating quick and straightforward.
- Precise Fit: Machined with a precise taper to ensure tight and accurate clamping of the bearing inner ring onto the shaft.
- Durable Construction: Made from high-grade steel to withstand the high forces involved in mounting and dismounting operations.
- Slotted Design: Features a full-length slot that allows for compression and a secure grip on the shaft.
- Standardized Dimensions: Conforms to international standards, ensuring interchangeability and compatibility with a wide range of bearings.
- Corrosion Resistant: Treated to resist corrosion, enhancing its durability in various industrial environments.
Common Applications
- Industrial Gearboxes: Used for mounting gears and bearings onto shafts, allowing for easier assembly and maintenance.
- Conveyor Systems: Essential for securing bearings on conveyor drum shafts, where regular maintenance is required.
- Paper and Pulp Machinery: Employed in rollers and other rotating components that operate under heavy loads.
- Mining and Construction Equipment: Ideal for crushers, vibrating screens, and other heavy machinery where components face extreme conditions.
- Large Fans and Blowers: Ensures that bearings supporting fan shafts can be easily replaced, minimizing operational downtime.
- Agricultural Machinery: Used in equipment like combines and balers for reliable bearing performance and serviceability.
- Steel Mill Equipment: Supports rollers and other critical components in demanding, high-temperature environments.
Benefits of Using the AHX 312
- Reduced Maintenance Time: The ability to easily withdraw the bearing significantly cuts down on the time required for repairs and replacements.
- Increased Machine Uptime: Faster maintenance cycles mean less downtime, leading to greater productivity.
- Protection of Components: Prevents damage to the shaft and bearing that can occur during the dismounting of press-fit bearings.
- Cost-Effective Solution: Provides a reliable mounting method that simplifies assembly and reduces long-term maintenance costs.
- Secure and Reliable Mounting: Ensures the bearing is firmly fixed to the shaft, preventing slippage and maintaining rotational accuracy.
- Versatility: Allows for the use of standard tapered bore bearings on simple cylindrical shafts, offering flexibility in machine design.
