Product Overview: The H 31/750 Adapter Sleeve
The H 31/750 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 750 mm diameter. As a critical component in our Adapter Sleeves collection, this sleeve simplifies the installation process, allowing for secure and precise positioning of the bearing without the need for a shoulder or other locating feature on the shaft. Part of the robust H 3100 Series, the H 31/750 assembly includes a lock nut and a lock washer, providing a complete and reliable solution for a wide range of heavy-duty industrial applications.
Adapter sleeves are the most commonly used components for locating bearings on a shaft, as they allow for the use of commercial-grade shafts with wider tolerances, reducing overall machining costs. The split design facilitates easy installation and removal, making it an essential accessory for efficient machinery maintenance and assembly.
