Product Overview: The H 308 Adapter Sleeve
The H 308 Adapter Sleeve is an essential component for mounting bearings with a tapered bore onto a 35mm cylindrical shaft. As a key part of our H 300 Series, this sleeve simplifies the installation and removal of bearings, providing a secure and precise fit. These Adapter Sleeves allow for the use of standard commercial shafts, eliminating the need for special machining and reducing overall assembly costs. The H 308 is supplied as a complete assembly, including the corresponding KM 08 lock nut and MB 08 lock washer, ensuring you have all the necessary parts for a reliable mounting solution.
Adapter sleeves are the most common method for locating bearings on a shaft. Their split design and tapered outer surface allow them to create a tight friction fit when driven into the tapered bore of a bearing. This mechanism securely locks the bearing at any position on the shaft, making it a versatile choice for a wide range of industrial applications. Explore our full range of Sleeves to find the perfect solution for your machinery.
Key Features of the H 308
- Complete Mounting Solution: Supplied with a high-quality lock nut and lock washer for secure fastening.
- Easy Installation: Facilitates the mounting of bearings with a tapered bore on cylindrical shafts without shoulders or locating rings.
- Versatile Positioning: Allows the bearing to be located at any position along a plain shaft.
- Accommodates Shaft Tolerances: Can be used on shafts with wider diameter tolerances compared to press-fit bearing arrangements.
- Durable Construction: Manufactured from high-quality steel to ensure strength, durability, and reliable performance under load.
- Slotted Design: The sleeve is slotted to allow for contraction, ensuring a tight grip on the shaft when the lock nut is tightened.
Common Applications
- Conveyor Systems: Used for mounting bearings in conveyor rollers and drive pulleys.
- Industrial Fans and Blowers: Provides a secure mounting for fan shaft bearings, ensuring stable and vibration-free operation.
- Agricultural Machinery: Ideal for equipment such as harvesters, balers, and tillers where robust bearing mounting is crucial.
- Pumps and Compressors: Ensures precise alignment and securement of bearings in various pump and compressor assemblies.
- Mining and Construction Equipment: Used in crushers, screens, and other heavy-duty machinery that operates in harsh environments.
- Textile and Printing Presses: Facilitates the mounting of bearings on rollers, ensuring smooth and consistent operation.
Benefits of Using the H 308
- Reduced Machining Costs: Eliminates the need for special steps or shoulders on the shaft, allowing the use of less expensive, straight shafts.
- Simplified Assembly and Dismantling: The sleeve design makes it easy to mount and dismount bearings, reducing maintenance time and effort.
- Enhanced Reliability: Provides a secure, concentric grip that prevents the bearing from slipping on the shaft, improving machine performance and lifespan.
- Increased Bearing Life: A proper fit ensures that the bearing's internal clearance is correctly set, maximizing its operational life.
- Flexibility in Design: Allows for more flexible machine design, as bearings can be easily positioned and adjusted on the shaft.
- Shaft Protection: The sleeve protects the shaft surface from damage that could occur during direct press-fitting of a bearing.
