Product Overview: The H 308 Adapter Sleeve
The H 308 adapter sleeve is an indispensable component for securely mounting tapered bore bearings onto cylindrical shafts. As part of our comprehensive H Series and specifically the H 300 Series Adapter Sleeves, the H 308 is precision-engineered to provide a firm and concentric fit, ensuring optimal bearing performance and extended service life. It is commonly used with spherical roller bearings and certain types of deep groove or cylindrical roller bearings that feature a tapered bore.
Our H 308 adapter sleeves are manufactured to high industrial standards, guaranteeing dimensional accuracy and reliability. They simplify the mounting and dismounting process of bearings, making them a preferred choice for applications where frequent maintenance or replacement might be required. When paired with a compatible lock nut (such as the KM 08 or MB 08) and lock washer, the H 308 provides an exceptionally secure and stable bearing arrangement, crucial for heavy-duty industrial machinery. Its design allows for easy installation without the need for additional shaft machining, saving both time and cost.
Key Features of the H 308 Adapter Sleeve
- Precise Tapered Design: Ensures an accurate and tight fit between the bearing's tapered bore and the cylindrical shaft.
- Easy Mounting and Dismounting: Facilitates straightforward installation and removal of bearings, reducing downtime for maintenance.
- High Concentricity: Provides excellent concentricity of the bearing on the shaft, which is critical for smooth operation and minimal vibration.
- Robust Construction: Made from high-quality materials to withstand demanding industrial environments and heavy loads.
- Versatile Compatibility: Ideal for use with a wide range of tapered bore bearings, including spherical roller bearings like the 22208 and 22308.
- Cost-Effective Solution: Eliminates the need for step shafts or expensive shaft machining, offering an economical mounting alternative.
- Secure Axial Location: When used with a lock nut and lock washer, it provides reliable axial positioning of the bearing.
Common Applications for H 308 Adapter Sleeves
- Conveyor Systems: Ensures secure mounting of bearings in material handling systems where shafts are subjected to varying loads.
- Textile Machinery: Provides stable support for rollers and spindles, contributing to precise and consistent operation.
- Mining Equipment: Used in heavy-duty machinery for robust bearing installation in harsh, dusty conditions.
