Product Overview: The H 39/500 Adapter Sleeve
The H 39/500 is a high-precision adapter sleeve designed for securely mounting bearings with a tapered bore onto cylindrical shafts with a 480mm diameter. As a crucial component in our H 3900 Series of Adapter Sleeves, it provides a reliable and convenient method for locating bearings on smooth or stepped shafts. The sleeve's split design, combined with a lock nut and lock washer (included), simplifies the installation and dismounting process, ensuring a tight and secure fit that prevents any axial movement of the bearing during operation.
Manufactured from high-quality steel, the H 39/500 adapter sleeve is engineered to meet rigorous industry standards, making it suitable for demanding industrial applications. It eliminates the need for special shaft machining and allows for wider shaft tolerances, offering a cost-effective and efficient mounting solution.
