Product Overview: The H 3120 Adapter Sleeve
The H 3120 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts. As a key component in our Adapter Sleeves collection, and part of the popular H 3100 Series, this sleeve provides a simple and effective method for securing bearings. It is specifically designed to locate a bearing with a 100 mm tapered bore onto a 90 mm diameter shaft, ensuring a precise and firm fit without the need for complex shaft machining. This assembly typically includes a corresponding lock nut and lock washer for complete installation.
Adapter sleeves are one of the most commonly used components for locating bearings, as they can be used on plain or stepped shafts. Their ease of installation and removal makes them ideal for a wide range of industrial applications, simplifying maintenance and reducing downtime. Our H 3120 sleeves are manufactured to meet stringent industry standards, guaranteeing reliability and performance in demanding environments.
Key Features of the H 3120
