Product Overview: The HE 315 Adapter Sleeve
The HE 315 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 75mm diameter. As a crucial component in our Adapter Sleeves collection and a part of the HE 300 Series, this sleeve provides a simple, reliable, and cost-effective method for securing bearings. It is supplied complete with a corresponding lock nut and lock washer, ensuring a secure fit and preventing loosening due to vibration or operational stresses. This assembly allows for bearings to be easily positioned at any point on a plain shaft and simplifies the dismounting process.
Key Features of the HE 315
- Complete Assembly: Supplied with a precision lock nut and lock washer for a secure and complete mounting solution.
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on smooth or stepped cylindrical shafts without the need for a locating shoulder.
- Easy Installation & Removal: The split sleeve design facilitates straightforward installation, adjustment, and dismounting of bearings.
- Secure Fit: When tightened, the sleeve provides a strong interference fit between the bearing and the shaft, ensuring reliable power transmission and preventing slippage.
- Accommodates Shaft Tolerances: Enables the use of commercial-grade shafting with wider tolerances, reducing manufacturing costs.
- Durable Construction: Manufactured from high-grade steel to ensure strength, durability, and resistance to wear and tear in demanding industrial environments.
Common Applications
- Conveyor Systems: Used to mount bearings on head and tail pulley shafts.
- Industrial Fans and Blowers: Secures bearings in large ventilation and air-handling units.
- Agricultural Machinery: Ideal for applications in combines, harvesters, and other equipment where reliable bearing mounting is essential.
- Mining and Quarrying Equipment: Suitable for crushers, screens, and other heavy-duty machinery.
- Pulp and Paper Mills: Used in rollers and processing equipment that operate under heavy loads.
- Power Transmission: A fundamental component in large gearboxes, plummer blocks, and other transmission assemblies.
Benefits of Using the HE 315 Adapter Sleeve
- Cost-Effective: Eliminates the need for expensive and precise machining of shafts, saving time and money.
- Enhanced Reliability: Provides a secure, 360-degree grip on the shaft, ensuring the bearing operates correctly and reducing the risk of premature failure.
- Increased Service Life: Protects the shaft surface from damage during bearing installation and removal, prolonging its operational life.
- Improved Maintenance Efficiency: Simplifies the process of bearing replacement, minimizing downtime and maintenance costs.
- Versatility: Allows for the axial positioning of the bearing at virtually any point along a shaft.
- Reduced Inventory: A single sleeve size can be used with several different types of bearings (e.g., self-aligning ball bearings, spherical roller bearings), simplifying stock management.
