Adapter Sleeve

Adapter Sleeve
An adapter sleeve is a cylindrical device that mounts tapered bore bearings onto a shaft with a cylindrical surface. It is commonly used in various industrial applications to simplify the installation and disassembly of bearings, especially in cases where a tapered bore bearing is required to be mounted on a shaft with a cylindrical surface.

Features and benefits:
  • Simplified bearing installation
  • Flexibility
  • Load distribution

Q: Why are adapter sleeves used in bearing applications?

Adapter sleeves are used to adapt larger bore bearings to smaller shafts or to facilitate mounting on tapered shafts, ensuring a proper fit and alignment.

Q: What types of bearings are commonly used with adapter sleeves?

Adapter sleeves are commonly used with spherical roller bearings, cylindrical roller bearings, and other types of bearings where a tapered bore is present.

Q: Can adapter sleeves accommodate different shaft sizes?

Yes, adapter sleeves are available in various sizes to accommodate different shaft diameters. They are designed to fit a specific range of shaft sizes and provide a secure mounting surface for bearings with tapered bores.
