Product Overview: The H 31/670 Adapter Sleeve
The H 31/670 is a precision-engineered adapter sleeve designed for mounting bearings with a tapered bore onto a cylindrical shaft with a 670mm diameter. As a vital component in our Bearing Accessories range, this sleeve is part of the robust H 3100 Series, which falls under the broader Adapter Sleeves category. Adapter sleeves simplify the mounting process, allowing for a secure and accurate fit on plain or stepped shafts. They are supplied complete with a corresponding lock nut and lock washer, providing a full assembly solution for demanding industrial applications.
Manufactured from high-quality steel, the H 31/670 ensures excellent durability and reliable performance. Its slotted design and tapered outer surface allow for a powerful interference fit when driven into the bearing's bore, preventing slippage and ensuring concentricity. This method of mounting is not only secure but also facilitates easier dismounting for maintenance or replacement, making it a preferred choice in heavy machinery.
Key Features of the H 31/670
- Precise Shaft Fit: Designed specifically for 670mm diameter cylindrical shafts.
- Simplified Mounting: Allows for easy installation of tapered bore bearings without the need for special shaft machining.
- Secure Locking: Comes as a complete assembly with a lock nut and lock washer to firmly secure the bearing in position.
- Durable Construction: Made from high-strength steel to withstand high radial loads and harsh operating conditions.
- Facilitates Dismounting: The design allows for straightforward removal of the bearing from the shaft, reducing maintenance time.
- Concentric Grip: The sleeve's taper ensures a tight, 360-degree grip between the bearing and the shaft, minimizing vibration.
Common Applications
- Mining and Quarrying: Used in large conveyors, crushers, and screening equipment where robust shaft mounting is critical.
- Pulp and Paper Mills: Essential for mounting bearings on large rollers and cylinders in processing machinery.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other heavy-duty equipment.
- Power Generation: Suitable for securing bearings in large turbines, generators, and industrial gearboxes.
- Marine and Offshore: Utilized in propulsion systems, winches, and deck machinery that operate under extreme loads.
- Industrial Fans and Blowers: Provides a stable and reliable mounting solution for large-scale ventilation systems.
Benefits of Using the H 31/670 Sleeve
- Cost-Effective Assembly: Enables the use of commercially available cylindrical shafts with a looser fit, reducing overall manufacturing costs.
- Increased Operational Reliability: The secure fit prevents fretting corrosion and shaft damage, extending the service life of both the bearing and the shaft.
- Reduced Downtime: The ease of mounting and dismounting simplifies maintenance procedures, getting machinery back online faster.
- Versatile Application: Can be used to position a bearing at any point along a smooth cylindrical shaft.
- Improved Equipment Performance: A firm, concentric mounting reduces vibration and noise, leading to smoother and more efficient operation.
- Full Mounting Solution: Supplied as a complete kit, ensuring all components are correctly matched for optimal performance.
