FAG (Schaeffler) adapter sleeves are essential accessories used to mount tapered bore bearings on cylindrical shafts, ensuring a secure and precise fit. These sleeves allow for easy bearing installation and removal without the need for additional shaft fixtures, promoting longer bearing life. They are commonly made of high-quality steel with a tapered bore on the inner surface, providing a true fit and enabling accurate axial positioning of the bearing.
Both adapter and withdrawal sleeves are available in various sizes and designs to accommodate different shaft diameters and bearing configurations. They play a crucial role in ensuring proper assembly, disassembly, and maintenance of bearing systems in industrial applications.
