AH3072-H

The AH3072-H withdrawal sleeve is a specialized mounting component engineered to secure bearings with a 1:12 tapered bore onto cylindrical stepped shafts. Specifically designed for metric shafts with a 340mm diameter, this sleeve features a robust 360mm nominal bore and a width of 167mm. What distinguishes the "-H" variant is its integrated oil injection technology. By incorporating precision-machined oil grooves and supply ducts, it allows for hydraulic pressure to be applied during the assembly and disassembly process. This significantly reduces the physical force required, minimizing the risk of surface scoring on the shaft and ensuring a perfect, interference fit even in heavy-duty industrial environments.

Beyond its basic dimensions, the AH3072-H is crafted for maximum durability and maintenance efficiency. The sleeve is typically used in conjunction with a hydraulic nut to facilitate a seamless "push-on" installation. Because it eliminates the need for complex locking washers or traditional groove nuts during the mounting phase, it streamlines the maintenance cycle of large-scale machinery in sectors like mining, paper milling, and steel production. With a total weight of approximately 21kg and a high-grade finish, it provides the structural integrity needed to maintain axial positioning under extreme radial loads, making it a reliable choice for engineers prioritizing long-term equipment uptime.
