Product Overview: The H 3260 Adapter Sleeve
The H 3260 is a high-quality adapter sleeve designed to mount bearings with a tapered bore onto a cylindrical shaft with a 300mm diameter. As a critical component in our Sleeves and Bearing Accessories range, this sleeve simplifies the mounting process, allowing for secure and precise positioning of bearings on plain or stepped shafts. Part of the robust H 3200 Series, the H 3260 comes complete with a lock nut and lock washer, providing a reliable assembly that prevents loosening during operation.
Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical shaft seat. Their split design and tapered outer surface ensure a tight, concentric fit when driven into the bearing's inner ring. This method is versatile, cost-effective, and allows for easy installation and dismounting without the need for specialized shaft machining. Whether for new equipment or maintenance, the H 3260 offers a dependable solution for a wide range of industrial applications.
Key Features of the H 3260
- Complete Assembly: Supplied as a complete set including the sleeve, a lock nut, and a lock washer for secure fastening.
- Split Design: Features a longitudinal slit that allows for easy installation and provides a firm grip on the shaft.
- Facilitates Mounting on Plain Shafts: Allows bearings to be positioned at any location on a smooth cylindrical shaft, simplifying design and reducing machining costs.
