Product Overview: The H 217 Adapter Sleeve
The H 217 is a high-quality adapter sleeve from our H 200 Series, designed to facilitate the mounting of bearings with a tapered bore onto cylindrical shafts. Specifically, this sleeve allows a bearing with an 85 mm tapered bore to be securely located on a 75 mm diameter shaft. As a crucial component in our range of Bearing Accessories and Adapter Sleeves, the H 217 provides a simple, reliable, and cost-effective method for bearing installation, eliminating the need for complex shaft machining. The assembly includes the slotted sleeve, a corresponding lock nut (KM 17), and a lock washer (MB 17) to ensure the bearing is firmly fixed in its operational position.
Key Features of the H 217 Adapter Sleeve
- Simplified Mounting: Allows for easy installation of tapered bore bearings on plain or stepped cylindrical shafts.
- Complete Assembly: Supplied as a complete set with a precision-engineered sleeve, a KM 17 lock nut, and an MB 17 lock washer.
- Secure Fastening: The lock nut and washer mechanism provides strong axial clamping, preventing loosening due to vibration or operational loads.
- Precision Machining: Manufactured with tight tolerances to ensure excellent concentricity and minimize run-out, contributing to smoother machine operation.
- Durable Construction: Made from high-strength steel to withstand mounting forces and operational stresses, ensuring a long service life.
- Easy Dismounting: The design also simplifies the process of bearing removal for maintenance or replacement.
Common Applications
- Industrial Fans and Blowers: Used to mount bearings on motor shafts, ensuring stable and reliable fan operation.
- Conveyor Systems: Essential for securing bearings on conveyor rollers and drive pulley shafts.
- Agricultural Machinery: Widely used in equipment like harvesters, combines, and balers where robust bearing mounting is critical.
- Pumps and Compressors: Provides a secure fit for bearings in various pump and compressor assemblies.
- Mining and Construction Equipment: Suitable for heavy-duty applications where machinery operates under harsh conditions.
- Paper and Textile Mills: Ensures precise and secure location of bearings on rollers and shafts in processing machinery.
- General Industrial Gearboxes: Facilitates the mounting of bearings on input and output shafts.
Benefits of Using the H 217 Sleeve
- Cost-Effective: Eliminates the need for expensive and time-consuming shaft machining, allowing the use of standard commercial shafts.
- Enhanced Reliability: Provides a secure, 360-degree grip on the shaft, ensuring the bearing is firmly positioned and reducing the risk of slippage.
- Improved Bearing Life: Proper and secure mounting helps to achieve the full operational lifespan of the bearing.
- Maintenance Friendly: Simplifies both installation and dismounting procedures, reducing downtime and labor costs during maintenance.
- Versatility: Can be used on any part of a smooth cylindrical shaft, allowing for flexible positioning of the bearing.
- Reduced Inventory: Allows a single tapered bore bearing to be used on shafts of different diameters by simply changing the adapter sleeve.
