Product Overview: The H 3984 Adapter Sleeve
The H 3984 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 420mm diameter. As a key component in our H 3900 Series, this sleeve simplifies the installation process, providing a secure and precise fit for large-scale industrial applications. Adapter Sleeves are the most commonly used components for locating bearings on a shaft, as they can be used on plain or stepped shafts. They are easy to mount and require no additional location on the shaft, making them a versatile and cost-effective solution.
This assembly includes the adapter sleeve, a corresponding lock nut (KM 84), and a lock washer (MB 84), ensuring that the bearing is firmly secured both axially and radially. The precision-engineered split in the sleeve allows for straightforward installation and dismounting, minimizing maintenance time and protecting the shaft from wear. Our H 3984 sleeves are manufactured from high-grade steel to ensure durability and reliability in demanding operational environments.
