Product Overview: The HE 216 Adapter Sleeve
The HE 216 is a high-quality adapter sleeve designed for securely mounting bearings with an 80mm tapered bore onto a 75mm cylindrical shaft. As a crucial component in our Bearing Accessories collection, this sleeve simplifies the installation and removal process, providing a reliable and concentric fit without the need for specialized shaft machining. Part of the versatile HE Series, the HE 216 assembly includes a precision-engineered sleeve, a corresponding lock nut (KM 16), and a lock washer (MB 16) to ensure the bearing is firmly fixed in its operational position.
As a leading supplier of industrial components, we provide Adapter Sleeves that meet stringent industry standards for dimensional accuracy and material quality. The HE 216 facilitates the use of standard commercial shafting, reducing overall costs and simplifying assembly, making it an indispensable part for a wide array of machinery.
Key Features of the HE 216
- Complete Mounting Solution: Supplied as a complete assembly with a sleeve, lock nut, and lock washer for straightforward installation.
- Facilitates Easy Mounting: Allows bearings with a tapered bore to be mounted on plain or stepped cylindrical shafts.
- Precision Machined: Manufactured with a precise taper to ensure a tight, concentric grip on the shaft and a secure fit with the bearing's inner ring.
- Slit Design: The sleeve is longitudinally slit, allowing it to contract and grip the shaft firmly when the lock nut is tightened.
- Durable Construction: Made from high-strength steel to withstand high mounting forces and operational loads, ensuring long-term reliability.
- Simplifies Dismounting: Greatly simplifies the process of dismounting bearings for maintenance or replacement.
Common Applications
- Conveyor Systems: Used in pulley and roller assemblies to secure bearings onto long shafts.
- Industrial Fans and Blowers: Provides a stable and reliable mounting for fan shaft bearings, accommodating high rotational speeds.
- Agricultural Machinery: Ideal for equipment where bearings need to be mounted securely on non-precision shafts, such as in harvesters and balers.
- Mining and Construction Equipment: Essential for heavy-duty machinery where robust and secure bearing mounting is critical.
- Plummer Block Housings: Commonly used with split plummer block housings to create versatile and serviceable bearing units.
- Textile and Paper Mills: Ensures precise and secure mounting of roller bearings in processing machinery.
Benefits of Using the HE 216 Adapter Sleeve
- Cost-Effective: Eliminates the need for expensive and time-consuming precision machining of shafts, allowing for wider shaft tolerances.
- Enhanced Reliability: Provides a secure and uniform grip on the shaft, preventing fretting corrosion and improving the operational stability of the bearing.
- Increased Bearing Life: Ensures correct radial clearance and a secure fit, which are critical for maximizing bearing service life.
- Simplified Maintenance: The design allows for bearings to be easily installed and removed from shafts without causing damage.
- Versatility: Enables a single bearing size to be used on shafts of slightly different diameters, increasing design flexibility.
- Global Standard: Manufactured to internationally recognized standards, ensuring interchangeability and consistent performance.
