Product Overview: The HE 213 Adapter Sleeve
The HE 213 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 60mm diameter. As a crucial component in our Adapter Sleeves collection, it simplifies the installation process, providing a secure and precise fit without the need for complex shaft machining. This sleeve is part of the HE Series, known for its reliability in demanding industrial applications. It is typically used with a corresponding KM 13 lock nut and MB 13 lock washer to firmly secure the bearing in its designated position on the shaft.
Key Features of the HE 213 Sleeve
- Simplified Mounting: Allows bearings with a tapered bore to be mounted on standard cylindrical shafts, eliminating the need for a shaft shoulder or other locating features.
- Secure Fitment: The tapered design ensures a tight, concentric grip on the shaft when the lock nut is tightened, preventing slippage and vibration.
- Compensates for Shaft Variations: Can accommodate minor variations in shaft diameter, ensuring a reliable fit even with commercial-grade shafting.
- Durable Construction: Manufactured from high-strength steel to withstand high mounting forces and provide long-term durability.
- Slotted Design: Features a longitudinal slot that allows for contraction, ensuring a firm grip along the entire circumference of the shaft.
- Easy Dismounting: Greatly simplifies the process of removing the bearing from the shaft for maintenance or replacement.
Common Applications
The HE 213 adapter sleeve is versatile and used across various industries for mounting bearings in equipment such as:
- Conveyor Systems: Secures bearings on drive rollers and pulleys.
- Industrial Fans and Blowers: Used in large ventilation and air-handling units.
- Agricultural Machinery: Found in harvesters, balers, and other farm equipment where components are subject to heavy loads.
- Mining and Construction Equipment: Essential for crushers, screens, and conveyor drives.
- Pumps and Compressors: Ensures stable and secure mounting of bearings on rotating shafts.
- Paper and Pulp Machinery: Used in rollers and processing equipment.
Benefits of Using the HE 213 Adapter Sleeve
- Cost-Effective Installation: Reduces manufacturing costs by allowing the use of less expensive, straight cylindrical shafts instead of stepped ones.
- Enhanced Reliability: Provides a 360-degree contact surface, improving the concentricity of the bearing on the shaft and leading to smoother operation.
- Reduced Downtime: The ease of mounting and dismounting bearings significantly cuts down on maintenance time.
- Increased Bearing Life: A secure and properly aligned fit minimizes stress on the bearing, helping to extend its operational lifespan.
- Versatility: Allows a single bearing size to be used on shafts of slightly different diameters by using different sleeve sizes.
- Improved Assembly Accuracy: Simplifies the process of achieving the correct internal clearance in the bearing during installation.
