Product Overview: The AHX 330 Withdrawal Sleeve
The AHX 330 is a precision-engineered withdrawal sleeve designed for the straightforward dismounting of bearings with a tapered bore from a 150mm cylindrical shaft seat. As a critical component in our Bearing Accessories range, this sleeve is part of the AHX Series and belongs to the broader category of Withdrawal Sleeves. Its primary function is to simplify the removal process, preventing damage to both the bearing and the shaft during maintenance or replacement. The sleeve is pushed into the bearing bore, which is mounted against a shaft shoulder, and a lock nut is then used to press the bearing off the sleeve.
Manufactured from high-quality steel, the AHX 330 ensures durability and reliable performance in demanding industrial environments. Its slotted design and precise taper allow it to grip the shaft securely while facilitating a smooth withdrawal process. This component is essential for large machinery where correct and efficient bearing maintenance is crucial for operational longevity.
Key Features of the AHX 330
- Simplified Bearing Dismounting: Specifically designed to make the removal of bearings with tapered bores quick and easy.
- Shaft Protection: Prevents scoring, gouging, or other damage to the shaft surface during the dismounting process.
- Durable Construction: Made from high-strength steel to withstand the forces exerted during bearing removal and ensure a long service life.
- Precision Machining: Features a precisely ground taper and external surface for a perfect fit and smooth operation.
- Slotted Design: The sleeve is slit, allowing for slight compression to ensure a tight grip on the shaft.
- Cost-Effective Maintenance: Reduces labor time and the risk of damaging expensive components, lowering overall maintenance costs.
