Product Overview: The HE 311 Adapter Sleeve
The HE 311 is a high-quality adapter sleeve designed to securely mount bearings with a tapered bore onto a cylindrical shaft. Specifically, it facilitates the mounting of a bearing with a 55mm tapered bore onto a 50mm diameter shaft. As a vital component in our Adapter Sleeves collection, the HE 311 is part of the versatile HE 300 Series and ensures a tight, reliable fit, simplifying the installation process and eliminating the need for complex shaft machining. This sleeve comes complete with a corresponding lock nut and lock washer, providing a full mounting solution.
Manufactured from durable steel to precise industry standards, the HE 311 adapter sleeve is essential for ensuring the correct positioning and secure operation of bearings in a wide range of industrial machinery. Its design allows for easy installation, adjustment, and dismounting, making it a cost-effective and practical choice for many applications.
Key Features of the HE 311 Adapter Sleeve
- Complete Mounting Kit: Supplied with a lock nut (KM 11) and a lock washer (MB 11) for secure and reliable fastening.
- Precise Fit: Engineered to mount bearings with a 55mm tapered bore onto a 50mm cylindrical shaft.
- Simplified Installation: Allows for easy mounting and dismounting of bearings without requiring shoulders, abutments, or special machining on the shaft.
- High-Quality Material: Constructed from durable steel to withstand operational stresses and ensure a long service life.
- Slit Design: Features a longitudinal slit that allows for tight clamping onto the shaft when the lock nut is tightened.
- Axial Adjustability: Enables precise axial positioning of the bearing on the shaft, which is critical for many applications.
Common Applications
HE 311 adapter sleeves are widely used across various industries to mount bearings, such as the 22311 Spherical Roller Bearing, in demanding environments:
- Conveyor Systems: Used for mounting bearings on head and tail pulleys, ensuring stable and reliable rotation.
- Industrial Fans & Blowers: Provides a secure mounting for fan shaft bearings, accommodating heavy loads and high speeds.
- Agricultural Machinery: Essential in equipment like combines and balers where components need to be robust and easily serviceable.
- Mining and Quarrying Equipment: Used in crushers, screeners, and conveyors that operate under harsh conditions.
- Pumps and Gearboxes: Ensures precise and secure location of bearings on shafts within industrial drive systems.
- Paper and Textile Machinery: Facilitates the mounting of roller bearings in processing equipment.
Benefits of Using the HE 311 Sleeve
- Cost-Effective: Eliminates the need for expensive and time-consuming shaft machining, allowing the use of standard commercial shafts.
- Enhanced Reliability: Provides a secure, 360-degree grip on the shaft, preventing slippage and ensuring concentric running of the bearing.
- Reduced Maintenance Time: The sleeve design simplifies both the installation and removal of bearings, minimizing machinery downtime.
- Increased Versatility: Allows bearings to be located at any position on a plain shaft, offering greater design flexibility.
- Improved Bearing Performance: A proper fit achieved with an adapter sleeve ensures optimal running clearance and extends the operational life of the bearing.
- Simplified Assembly: The complete kit (sleeve, nut, washer) provides everything needed for a straightforward and secure installation.
