Adapter sleeves are commonly used to secure tapered bore bearings to cylindrical journals. They can be used on both smooth and stepped shafts.
This accessory facilitates installation without requiring additional space on the shaft. When used on smooth shafts, the bearing can be secured anywhere on the shaft. When used on stepped shafts, adapter sleeves, combined with L-shaped spacers, provide more precise axial positioning of the bearing, facilitating installation and removal.
