Product Overview: The H 3138 Adapter Sleeve
The H 3138 is a high-quality adapter sleeve designed to mount bearings with a tapered bore onto a 190mm cylindrical shaft. As a crucial component in our Adapter Sleeves collection, this sleeve simplifies the installation process, providing a secure and reliable fit without the need for complex shaft machining. Part of the robust H 3100 Series, the H 3138 is supplied as a complete assembly, including the corresponding lock nut and lock washer, ensuring you have all the necessary components for a successful mounting.
Adapter sleeves are one of the most commonly used methods for locating bearings on a shaft. They allow for wider shaft tolerances compared to direct mounting, making them a cost-effective and versatile solution for a vast range of industrial machinery. Whether for new installations or maintenance, the H 3138 provides a dependable method for achieving precise bearing positioning and securement.
Key Features of the H 3138 Adapter Sleeve
- Complete Assembly: Supplied with a precision lock nut and a secure lock washer for a full mounting solution.
- Facilitates Easy Mounting: Enables bearings with a tapered bore to be fitted onto smooth or stepped cylindrical shafts with ease.
- Secure and Reliable Fit: The tapered design ensures a strong, concentric grip on the shaft when the lock nut is tightened, preventing slippage.
- Versatile Application: Suitable for a wide range of industrial applications, accommodating various bearing types like spherical roller and self-aligning ball bearings.
- Cost-Effective Design: Eliminates the need for special shaft shoulders, keyways, or heat treatment, reducing manufacturing costs and complexity.
- Simplified Dismounting: The design allows for straightforward removal of the bearing for maintenance or replacement.
Common Applications
- Large Industrial Fans and Blowers: Securely mounts large bearings in air handling units, ensuring stable and long-lasting operation.
- Conveyor Systems: Used to mount bearings on long conveyor shafts where precise machining is difficult.
- Mining and Construction Equipment: Provides robust bearing mounting in machinery subjected to heavy loads and vibration, such as crushers and screening equipment.
- Pulp and Paper Mills: Essential for mounting bearings in rollers and drums where reliability is critical for continuous production.
- Agricultural Machinery: Employed in heavy-duty equipment like combines and balers for secure shaft and bearing arrangements.
- Power Transmission Systems: Widely used in gearboxes, plummer blocks, and other power transmission assemblies.
Benefits of Using the H 3138 Sleeve
- Enhanced Installation Efficiency: Significantly reduces the time and effort required to mount or dismount bearings.
- Improved Machine Reliability: Provides a firm, 360-degree grip that enhances rotational accuracy and reduces vibration.
- Reduced Maintenance Costs: The ease of dismounting simplifies bearing inspection and replacement, minimizing downtime and labor costs.
- Accommodates Shaft Tolerances: Allows for the use of commercial-grade shafting, which can lower overall assembly costs.
- Increased Bearing Life: Ensures proper interference fit and support for the bearing's inner ring, preventing premature wear and failure.
- Flexible Positioning: The bearing can be located at any position along a plain shaft, offering greater design flexibility.
