Product Overview: The HE 317 Adapter Sleeve
The HE 317 is a high-quality adapter sleeve designed for securely mounting bearings with a tapered bore onto an 80mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection, it belongs to the robust HE 300 Series. This sleeve simplifies the installation process, allowing for the use of standard commercial shafts and eliminating the need for special machining. The HE 317 is supplied as a complete assembly with a corresponding lock nut and lock washer, ensuring a tight, concentric fit that prevents slippage and enhances the operational life of the entire bearing arrangement.
Adapter sleeves are a cost-effective and reliable method for locating bearings on a shaft. The HE 317's design facilitates easy mounting and dismounting, making it an essential accessory for maintenance and assembly in a wide range of industrial machinery.

Key Features of the HE 317
- Complete Mounting Solution: Supplied with a precision lock nut (KM 17) and lock washer (MB 17) for a secure and complete installation.
- Facilitates Tapered Bore Mounting: Enables bearings with a 1:12 tapered bore (e.g., 1317, 2317, 22217) to be mounted on standard 80mm cylindrical shafts.
- High-Quality Construction: Manufactured from durable steel to withstand high loads and ensure long-term reliability.
- Slit Design: Features a longitudinal slit that allows for effective clamping and a tight grip on the shaft when the lock nut is tightened.
- Simplified Installation: Allows for easy positioning of the bearing anywhere on the shaft without the need for shoulders or locating rings.
- Protects Shaft Integrity: Prevents direct contact and wear between the bearing and the shaft, simplifying dismounting and reducing potential shaft damage.
Common Applications
- Conveyor Systems: Used to mount bearings on head and tail pulley shafts, ensuring reliable operation.
- Industrial Fans and Blowers: Provides a secure mounting for fan shaft bearings, accommodating high rotational speeds.
- Agricultural Machinery: Essential for mounting bearings in equipment like combines, balers, and tillers where robust performance is critical.
- Mining and Quarrying Equipment: Used in crushers, screeners, and conveyors that operate under heavy loads and harsh conditions.
- Pumps and Compressors: Ensures precise and secure location of bearings on pump shafts and in compressor assemblies.
- Paper and Pulp Machinery: Applied in rollers and presses to facilitate reliable bearing performance and easy maintenance.
- Construction Equipment: Utilized in mixers, cranes, and other heavy machinery requiring strong and dependable bearing arrangements.
Benefits of Using the HE 317
- Cost-Effective: Eliminates the need for expensive, custom-machined stepped shafts, allowing the use of standard, lower-cost shafting.
- Enhanced Reliability: Provides a secure, 360-degree grip on the shaft, ensuring concentricity and reducing vibration.
- Ease of Maintenance: Simplifies both the mounting and dismounting of bearings, significantly reducing downtime and labor costs during maintenance.
- Increased Bearing Life: A proper and secure fit minimizes fretting corrosion and internal clearance issues, extending the service life of the bearing.
- Versatility: Allows bearings to be accurately positioned and adjusted along the length of a shaft, offering greater design flexibility.
- Accommodates Shaft Tolerances: Can be used on shafts with wider commercial tolerances compared to bearings with cylindrical bores.
