Product Overview: H 39/670 Adapter Sleeve
The H 39/670 is a high-strength adapter sleeve designed for mounting bearings with a 670mm tapered bore onto a 630mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection, it provides a simple and reliable method for securing large bearings without the need for complex shaft machining. Part of the H 3900 Series, this sleeve is indispensable in heavy industrial applications where robust and secure mounting is paramount. The assembly, which includes a corresponding lock nut and lock washer, ensures that the bearing is firmly positioned on the shaft, facilitating both installation and maintenance.
Our adapter sleeves are manufactured to precise industry standards, ensuring a perfect fit and long-term performance. The H 39/670's slotted design and external taper allow it to be tightened into place, creating a powerful friction grip between the bearing, sleeve, and shaft. This method simplifies the assembly process and provides a cost-effective solution for a wide range of machinery. Explore our full range of Sleeves to find the ideal component for your application.
Key Features of the H 39/670
