Product Overview: The HE 211 Adapter Sleeve
The HE 211 is an essential component for mounting bearings with a tapered bore onto a cylindrical shaft. Specifically designed for a 50mm shaft diameter, this adapter sleeve allows for the secure and precise fitting of bearings with a 55mm tapered bore, such as the 1211 or 22211. As a part of our HE Series collection, the HE 211 is a high-quality Adapter Sleeves that simplifies bearing installation and removal, making it a cost-effective and reliable choice for various industrial applications. Each assembly typically includes a lock nut and lock washer to ensure the bearing is firmly secured in its operational position.
Key Features of the HE 211
- Easy Installation: Simplifies the process of mounting tapered bore bearings onto straight, uniform-diameter shafts.
- Secure Fit: Provides a strong, concentric grip on the shaft, preventing slippage and ensuring stable bearing performance.
- Complete Assembly: Designed to be used with a corresponding lock nut (KM 11) and lock washer (MB 11) for a secure setup.
- Facilitates Dismounting: The design makes it easier to remove bearings from shafts during maintenance or replacement.
- Cost-Effective: Eliminates the need for expensive, specially machined stepped shafts, allowing the use of standard commercial shafting.
- Durable Construction: Manufactured from high-grade steel to withstand high loads and ensure long-term reliability.
Common Applications
- Conveyor Systems: Used to mount bearings on long shafts in pulley and roller assemblies.
- Industrial Fans & Blowers: Ensures secure bearing mounting in high-speed rotational equipment.
- Agricultural Machinery: Ideal for applications in harvesters, tractors, and other farm equipment where reliability is key.
- Pumps and Gearboxes: Provides a stable and precise method for mounting bearings in power transmission systems.
- Mining and Construction: Suitable for heavy-duty machinery that operates under demanding conditions.
- Paper and Pulp Mills: Used in roller and press sections where secure bearing fixation is critical.
- Textile Machinery: Ensures smooth operation by providing reliable support for rollers and shafts.
Benefits of Using the HE 211
- Enhanced Machine Uptime: A secure mounting reduces the risk of bearing failure, leading to less downtime and more productive operations.
- Simplified Maintenance: The ease of mounting and dismounting reduces the time and labor required for bearing replacement.
- Increased Versatility: Allows bearings to be positioned at any point along a smooth shaft, offering greater design flexibility.
- Improved Bearing Life: Ensures correct and firm seating of the bearing, which helps in achieving maximum operational life.
- Reduced Costs: By enabling the use of less expensive straight shafts, it lowers overall machinery manufacturing and maintenance costs.
- Reliable Performance: Guarantees a secure and stable connection between the bearing and shaft, even in applications with high vibration.
