Product Overview: The H 3980 Adapter Sleeve
The H 3980 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 380mm diameter. As a critical component in our Adapter Sleeves collection and part of the robust H 3900 Series, this sleeve simplifies the installation process, allowing for secure and precise positioning of bearings without the need for complex shaft machining. It is supplied as a complete assembly, including a corresponding lock nut and lock washer, providing a comprehensive solution for heavy-duty industrial applications.
Adapter sleeves like the H 3980 are essential for accommodating wider shaft tolerances and facilitating easy dismounting for maintenance or replacement. The sleeve's slotted design and tapered outer surface ensure a tight friction fit when the lock nut is tightened, firmly securing the bearing to the shaft. This method is widely used in machinery where reliability and ease of assembly are paramount.
