Description
High-Strength Custom Forging with Thermal Fit and Easy Disassembly Design
Product Description
The Forged Roller Shaft and Sleeve Assembly is specifically engineered for rolling mill systems and other heavy-duty industrial machinery requiring superior strength and precision. Both the roller shaft and sleeve are manufactured through high-quality forging processes to ensure excellent mechanical properties, wear resistance, and dimensional integrity under high loads and harsh working environments.
To improve operational efficiency, the system utilizes a medium-frequency induction heating and internal water cooling technique. This dual thermal mechanism rapidly creates a temperature-induced gap between the roller sleeve and the shaft, significantly increasing disassembly speed and minimizing mechanical stress on components.
During assembly, a motor-driven expansion device with a specially designed clamping structure allows precise control of the sleeve’s positioning. This enables accurate gap adjustment, reduces installation errors, and enhances overall system stability and flexibility.
Key Features
Precision Forging: Both components are forged from premium alloy steel for enhanced strength, durability, and fatigue resistance.
Fast Maintenance: Thermal expansion and cooling system allows for quick, safe disassembly without damaging parts.
Adjustable Assembly: Motor-driven expansion ensures precise gap fitting for optimal sleeve-to-shaft contact.
Reduced Downtime: Easy maintenance and simplified disassembly streamline operational workflows.
Customizable Options: Material grade, dimensions, and surface treatments can be customized to meet specific operational requirements.
