Product Overview: The HE 217 Adapter Sleeve
The HE 217 is a high-quality adapter sleeve designed to securely mount bearings with a tapered bore onto a standard 75mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection, it simplifies the assembly process, providing a reliable and concentric fit without the need for specialized shaft machining. This sleeve is part of the HE Series, which offers enhanced mounting capabilities for various industrial applications. Each HE 217 assembly includes the slotted sleeve, a corresponding KM 17 lock nut, and an MB 17 lock washer, ensuring that the bearing is properly secured against the shaft.
Key Features of the HE 217 Sleeve
- Complete Mounting Solution: Supplied as a complete set with a lock nut and lock washer for immediate installation.
- Facilitates Easy Mounting: Enables bearings with an 85mm tapered bore to be fitted onto 75mm cylindrical shafts.
- Precision Machined: Manufactured to strict tolerances to ensure a secure and accurate fit, minimizing vibration.
- Slotted Design: The sleeve is slit, allowing it to contract and clamp firmly onto the shaft when the lock nut is tightened.
- High-Quality Material: Constructed from durable steel to withstand high mounting forces and operational stresses.
- Versatile Compatibility: Suitable for use with various bearing types, including self-aligning ball bearings and spherical roller bearings like the 22217.
Common Applications
- Industrial Fans and Blowers: Provides secure mounting for fan shafts, ensuring stable and balanced rotation.
- Conveyor Systems: Used to mount bearings on head and tail pulleys, facilitating reliable material handling.
- Agricultural Equipment: Essential for mounting bearings in machinery such as combines, balers, and tillers.
- Pumps and Gearboxes: Ensures precise and secure positioning of bearings on shafts within power transmission systems.
- Mining and Construction Machinery: Offers a robust mounting solution for equipment operating in harsh and demanding environments.
