Product Overview: The H 2318 Adapter Sleeve Assembly
The H 2318 is a high-quality adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a diameter of 80mm. As a crucial component in our Adapter Sleeves category, it is part of the versatile H 2300 Series. This complete assembly, which includes the adapter sleeve, a corresponding lock nut (KM 18), and a lock washer (MB 18), provides a simple, reliable, and cost-effective method for locating bearings on plain shafts. The sleeve's split design and tapered outer surface ensure a tight, concentric fit when the lock nut is tightened, securely fastening the bearing in place.
Our H 2318 adapter sleeves are manufactured to precise industry standards, ensuring interchangeability and consistent performance. They are essential for applications where stepped shafts are impractical or not cost-effective, offering a straightforward solution for a wide range of industrial machinery.

Key Features of the H 2318
- Complete Mounting Solution: Supplied as a full assembly including a slotted sleeve, a lock nut, and a lock washer for convenient installation.
- Facilitates Easy Mounting: Simplifies the process of mounting tapered bore bearings onto cylindrical shafts.
- Secure Bearing Location: Provides a strong and reliable interference fit, preventing axial movement of the bearing on the shaft.
- Use on Plain Shafts: Eliminates the need for expensive shaft shoulders, keyways, or other special machining.
- Compensates for Shaft Tolerances: Can be used on commercial-grade shafting, allowing for wider diameter tolerances compared to direct bearing fits.
- High-Quality Construction: Made from durable steel to withstand high mounting forces and operational loads, ensuring long service life.
Common Applications
- Conveyor and Pulley Systems: Used to mount bearings on long shafts where stepped machining is difficult.
- Industrial Fans and Blowers: Provides secure mounting for fan shaft bearings, ensuring stable and balanced rotation.
- Agricultural Machinery: Ideal for equipment such as combines and balers, where robust and simple bearing arrangements are required.
- Mining and Construction Equipment: Supports heavy-duty bearings in crushers, screens, and conveyor drives.
- Pumps and Gearboxes: Enables precise positioning of bearings on input and output shafts.
- Textile and Printing Machinery: Ensures accurate alignment and secure fitting of rollers and cylinders.
Benefits of Using the H 2318 Adapter Sleeve
- Reduced Machining Costs: Saves time and money by allowing the use of less expensive, un-stepped commercial shafts.
- Simplified Installation and Dismounting: The sleeve design allows for bearings to be mounted or removed quickly without causing damage to the shaft or bearing.
- Enhanced Rigidity: Creates a solid, 360-degree contact between the bearing and shaft, improving the overall stiffness of the assembly.
- Versatility: Allows the same bearing to be used on shafts of slightly different diameters by simply changing the sleeve.
- Improved Maintenance Efficiency: Speeds up the process of bearing replacement, minimizing machinery downtime.
- Reliable Performance: Ensures accurate and secure positioning of the bearing, contributing to smoother operation and extended component life.
