Product Overview: H 309 Adapter Sleeve
The H 309 Adapter Sleeve is a crucial component used for mounting bearings with a tapered bore onto a cylindrical shaft. Specifically designed for a 40mm shaft diameter, this sleeve facilitates a secure and precise fit for bearings with a corresponding 45mm tapered bore. As part of our extensive H 300 Series, the H 309 provides a simple and cost-effective method for locating bearings on smooth or stepped shafts. The complete assembly, which includes a high-quality lock nut and lock washer, ensures that the bearing is firmly positioned, preventing axial movement and ensuring optimal performance.
Adapter sleeves are one of the most commonly used bearing accessories because they eliminate the need for special shaft machining, shoulders, or locknuts to secure the bearing. This simplifies both installation and dismounting processes, saving time and reducing maintenance costs. Our H 309 sleeves are manufactured to meet precise industry standards, guaranteeing reliability in a wide array of industrial applications.
Key Features of the H 309 Sleeve
- Easy Installation: Allows for the mounting of tapered bore bearings on cylindrical shafts without the need for a shaft shoulder or special tooling.
- Secure Fit: The tapered design ensures a tight interference fit between the bearing and the shaft when the lock nut is tightened.
- Complete Assembly: Supplied as a complete set including a corresponding lock nut (KM 9) and lock washer (MB 9) for a full mounting solution.
- Precision Machining: Manufactured with high precision to ensure accurate shaft alignment and concentricity.
- Versatility: Can be used on both plain and stepped shafts, offering flexibility in machine design.
- Durable Construction: Made from high-strength steel to withstand demanding operational conditions and ensure long service life.
Common Applications
- Industrial Fans and Blowers: Used to secure bearings on motor shafts for reliable and vibration-free operation.
- Conveyor Belt Pulleys: Provides a robust method for mounting pulley bearings, which are often subjected to heavy loads.
- Agricultural Machinery: Ideal for equipment like combines and harvesters where components need to be easily serviced in the field.
- Pumps and Gearboxes: Ensures precise and secure bearing positioning on shafts within various power transmission systems.
- Mining and Construction Equipment: Suitable for heavy-duty machinery where reliable bearing mounting is critical for safety and performance.
- Textile and Paper Mills: Used on rollers and drums to facilitate easy bearing replacement during routine maintenance.
Benefits of Using the H 309 Adapter Sleeve
- Reduced Machining Costs: Eliminates the need for expensive and time-consuming precision machining of shaft shoulders.
- Simplified Maintenance: Facilitates quick and easy mounting and dismounting of bearings, reducing downtime.
- Enhanced Bearing Life: Provides a secure, 360-degree grip that promotes correct alignment and extends the operational life of the bearing.
- Design Flexibility: Allows bearings to be positioned at any point along a smooth shaft, simplifying assembly design.
- Shaft Protection: The sleeve protects the shaft surface from damage that could occur during direct bearing mounting or removal.
- Improved Reliability: Ensures a consistently tight fit, which is crucial for high-speed applications or those with significant vibration.
